so that's where we're going to set the wire speed here so it basically just
went up heat 1 heat range where button the flooding the two of these together
one thing you want to check as well just looking at you want to make sure that if
you do your spot welds and stop a lot of times there's a little ball on the end
of this is a little bit of multi metal that was left on the end of the the
welding wire because that is thicker than the welding wire takes a little
more heat to get that melted in so your first little bit of weld may actually be
a little cold because you can't get it to flow out so I like to try and flip
off the ends to get a fresh piece of wire before we start again
so we have a piece here
and i'm going to do another another spot weld or stitch weld on here
so that
that's how i like to do it and show you guys we got a hundred percent
penetration
that's the backside and what I really want to show you guys this is really
killer
this is what i love you out of joke and get that on there
look how flat that that well it is flat man I mean that's that requires almost
no no grinding turn it a little bit so you can see it's nice and flat and you
don't have a lot
raised up over top of the panel that's because i turn the heat range up to get
it a little hot
a little a little hotter so i could really melted in there melt the two of
them together so that's what you want I mean that's almost a factory factory
work and spot-weld if you do that on you know if you're putting together a pinch
weld or something you can get your machine setup like that you could you
could pull some guys with that
so i'll tell you what i like to set it together
I'm sorry set up the machine and weld it together to get there is nice flat flat
wells like that and again that's that's part of the key of set your machine up
ahead of time you sit there and play with your settings get it just right and
save you some hassle you know you start off with it with the machine setup just
on point in your life you have like 12 like that
so that's a hundred percent penetration one well that we did earlier and i just
wanted to show you guys I set the Machine up incorrectly
there's a one on this one I set up too cold
this is either from holding the big gun too far away or maybe the settings on
the machine were incorrect or you could have had that little ball on the end of
the wire like I was talking about and you can see that it's kind of raised
really far up above is like a ball and a raised over top of it
so you want to try to avoid that we did get penetration through sort of but
you're gonna have to grind almost your welds on top of the paddle so you're
going to grind ninety percent of your weld away because of that you're going
lose your virginity because it's not really melted into the into both pieces
its kind of sitting on top
so if your if your welds are looking like that we're sitting real proud or
you know sitting tall on top of the panel . a machine and get it a little
turn it up the heat up a little bit return your wires feet down a little bit
to get it just right cause that's that's not what you want that's what you're
gonna have to put extra excessive heat into the panel by grinding that
so that's a cold weld next thing I was going to show and I'll do it on this one
we have with no gap here just to show you the process when you're welding a
panel together you're going to be doing what's basically called stitch welding
so you're going to be you're going to be welding a bunch of these little spot
welds over top of each other you're going to be overlapping them when you're
doing a panel repair
especially if it's an exterior repair the most anywhere you want to completely
seal up that gap your welding together
so if you leave a gap or a pinhole that you don't weld up
that's an area that moisture can get in ruskin start
and even though you're going to prime it or your coat it still could be some
moisture that can get in there and rust out from the inside so i would try and
well the whole entire panel
I do the way to do that is with stitch welding you're going to weld a few in a
row and then you're going to jump around to another spot and let it that area
cool and you jump to another spot weld a little more and jump around so I'll show
you I'll do three or four here in a row and then we'll show you what it looks
like on this on this piece here
yeah
that's a little hot but quick
here we go so you can see there's no gap in between ours overlapping step back
step in each of my welds that I'll turn it again
we're pretty flat you know those welds aren't sitting up real tall like they
were on that other piece we just showed you
they're still pretty flat not much grinding you're going to have to do that
you're not gonna have to do it on a grinding to get that smooth you know and
go over that couple passes between it'll be pretty smooth out and then from there
you can move on and and you know your next piece now one one thing you want to
actually show you here as well as your backside getting a hundred percent
penetration and we're talking about these pieces are completely fused
together they're not the world's not just sitting on top or nice and fused
together
one thing you have to remember though is you're fighting a war pitch the whole
entire time will turn this off here so you can hear a little better
so you're fighting the war pitch the whole entire time you're you're doing
this
so when you're walking like that you're going to do
maybe two three maybe four quick stitch welds like that and you're gonna want to
let that cool going to jump to the next spot a trick you can do if you're trying
to keep the panicle have to do those couple of stitch welds you can use a
little air nozzle and took their lineup and just blow off that area we're doing
what that's doing is you're going to keep the peace back down you're keeping
the heat soak from spreading
there's sort of minimizing the warpage a common misconception that a lot of
people have is that they think that if they quick
cool the piece down or if they put water on it or something like that they can
completely stopped warpage and that's it's just not possible warpage happens
no matter what
it's just a matter of how much warpage will happen if you're walking onto flat
pieces like this with no structural rigidity around them
you're going to get warpage no matter how much you try with
and the cool each piece you're going to get a little bit of warpage you can
reduce it by using this
I do not suggest using water if it's especially if it's something that's bare
metal because what are you doing we're trying to fight roster trying to stop
rust
well by introducing water onto a bare metal part and a well bits of virgin
clean metal weld already putting moisture into and starting the rusting
process even on a molecular level
you're still starting that so i like to use compressed air because it's
generally if you have a good drying system you're not going too much water
in the air and you're just calling it down and then you can move on
so you can cool the area down or you can just let it cool on its own depending on
what you put into it
jump over to an area that's pretty far away we usually the way I do is I take
my gloves off and if I can touch the panel and it's not hot to the touch and
I can i can do a little bit of welding if it's just barely you know luke warm
you'll be ok but if it's hot to the touch do not start welding back on that
piece again you need to let it cool down you need to walk away in the court with
the air nozzle or do something to get that panel back down this you keep
welding on and he effect of the heat affected zone is going to go route going
to go out like that and then your whole panel is going to be working you gotta
mess on your hands
so last couple of things it's just some tips and tricks or some tools that I
like to use that are really helpful
other than the ones we just carry talked about one of these little dramatic angle
grinders like this so really great
I keep one of these handy at all times i really like these for standing well so
i'll throw a little 36 grit sanding discs on it and what I do is when you're
standing your welds you want to be standing across the world like that
just knock down any high spots so you want to try not to be gouging if you can
if you have a sanding disc that's really go to fresh one
you can get in and sand just on the world
you've got to be really careful because you get off that well a little bit then
you're standing in your fresh metal on either side
i'm going to start making the metal really thin and
it's going to crack around itself a lot of times I'll quickly hit it like this
across the world
it will show me where there's any high spots sandoz down and but yeah this
guy's really handy to use another thing that if you're just learning or your
beginner and you want to a your your little intimidated about doing that
doing the stitch wedding spot welding
we have a spot weld kit that has this cool little nozzle here you can put on
to this and what this does it has these little legs here
that's the key what you do is you you want to thread your standard nozzle and
this fits any tweco style porch
so if you have a if you have a make water other than Eastwood that has tweco
consumables
he should be able to use this this tip here you thread it on like that and cut
the excess off here and I will cut this down just a little bit so you thread
this guy on in place for the tweaker nozzle this fits any any well do even if
you don't have an East what it has to go consumables you can use this what you do
with this it's that's the perfect height for doing a spot weld just like this so
I'll turn this so you guys can see there and video land
so you can see the you know this sets your your height and you can hit the
trigger and get a get a perfect spot well 20 or stitch one every time
so you don't have to think about it you know you can jump around to your height
set to him your height set
that's a big issue that beginners have is setting their their height there's
they're too high or too low and they're melting the wire to the tip so this get
that perfect height and push down on the piece like that your trigger boom is
that you've got a really nice spot weld
so she uses the same settings just it's a cool way to set your your height off
of the paddle and you can just swap back to your normal one if you're doing
normal or welding or you don't need it
so the the other part of that kit
that's handy there's these spotlight pliers
so what these are good for is if if you're welding two pieces together what
you're doing like a pinch weld or something like that what you're doing a
true spot weld or plug well when you're drilling a hole through the top piece
you can use these it clamps the two pieces of metal together tightly and the
cool thing we've done is we've made this
it's not so we're talking about it fits right inside like that
so you can fit inside you can set you could pretty much it's a no brainer at
that point you just hit the trigger boom you got a perfect spot well so please
come separately or you can buy this all in a kit but these are a cool one for
doing consistent spotters stitch welds next thing we have
we didn't really show up in this video but these are really great for setting
up your panels these little pinch weld clamps a little thumb screws on the top
and have a ton of clamping force you
it's incredible how much they have so with these you can you can do the edge
of a panel and tighten it down the whole pieces together
I got a ton of these my box that I used to mock up a panel use these for the
edge of the panel to keep everything kind of tight or where it needs to be
these are really good to have not just for pinch welds but just for general
fabrication and set up a panel for trying to mock something up you can use
these to set a panel in place and see what you need to do
they're extremely handy you can use them for cheap metal welding with your big if
you're setting up a panel on the edges here like this one I use that clamp the
ends with the pinch weld clamps and i was able to do this is his first couple
tack welds the other two things are going to show you is
these panel clamps here he's walking paddle clamps
he's a really handy we offer them a bunch of different sizes these are my
two favorites here
these are great for clamping a panel in place so if you're doing something large
like a quarter panel
we're doing a big patch you need to kind of check your check your progress to see
where it's at
it's fitting correctly or if you're just trying to get a panel
you know panels parallel and flush you can use those the virtual few pieces you
clamp them together again they have great holding power
I keep i would suggest getting as many as you can afford because you know an
old saying is you can never have too many clamps
when you're when you're working on an old car doing fabrication last thing is
if you're doing small patch panels
you don't want to buy a huge sheet of sheet metal we do at Eastwood offer a a
patch panel repair kit in both steel and aluminum that these here is our this
here is our steel get this is actually aluminized steel
so if you think of the exhaust if you ever got exhaust tubing at a coffee shop
or at a local parts store has that still rich coating on it
that's exactly what this has on that's for a corrosion that keeps it from
rusting so that way when you're doing the repair
you only need to grind on just the edge you can well just on the edge and it's
only the area that you're welding you have to worry about any type of rust
form that's already got a coating on it that keeps it from flash rusting
so that's really great extra benefit of buying this
it comes with a bunch of different pieces that you can do most general
repairs with you start getting into larger things that quarter panel door
skins things like that
this might be not quite large enough but this can take care of most any patch
panels that you need to make you can easily do it with that
it also comes with these strips here you can use you can use these that backers
we're using them today just to show you know what we're welding together
you can use these pieces to back up back of a of a piece if you're welding
similar what we get with the backing plate
you can actually weld wanted backing strip to it -
up to help you out if you're a beginner so that's everything I got today for the
basics on a MIG welding sheet metal
