as mark on today's rd corner we're going to teach you how to make well show your
real-world application by preparedness door skin here we're going to show you
the performance of value of these units and how they can pay for themselves in
the first job
let's get started
all right before getting to repair in that door teach you how to make well
real quick first thing comfortable position second is holding your torch
I'm right-handed or left-handed to be the opposite hear what you want to do is
get your left hand almost like you're holding a pool cue
this thing's going to steady your got it's going to keep that correct work
distance from your piece that steady hand they'll keep it a nice steady
movement here the other thing your ground clamp what you want to do is try
and get that as close as possible to the weld area machine setup very easy inside
the door here we have your chart come across the top to your material you'll
see 20 gauge the setting is voltage on e wire speed on for and what I like doing
on the sheet metal is just running a little bit hotter i'll just take it up
another notch on the voltage they're all right the first thing you want to do cut
the wire so you've got about a quarter inch stick out
now we're going to get in position like we talked about before your free hand is
your steady rest get the torch down there and what we're going to do is a
spot well it's just going to be a one-second blast this is what you want
to see a nice spot weld on about fifty percent each of the panels and a real
nice shallow crown there this will require almost zero blending they're
just a couple hits with a flap discs you're good to go now what we're going
to do is take that spot well take me we just learned turn into a stitch well
basically stitch welding is taking a series of spot-welds putting about fifty
percent overlap together this is what you use for your patch panel your
quarters
let's show you this technique
what you see is our initial spot and then our stitch welding which is
essentially a series of spot-welds about fifty percent overlap right here nice
low-crown make that well very easy to blend final one you're going to use for
the sheet metal is plug welding what we have here is a piece of metal
we got some three sixteen holes that we drilled or punched into what allows you
to do is take two pieces of metal together join them
we're going to weld right through that hole there
all right now what we're going to do show you some heavier stuff we've got
some 316 play here just some cold rolled steel what we're going to do is put
these the other and T well and also a lap well we're going to do is show you
the gun movement here that all short proper penetration a typical government
will be a standard push in a straight line here but to assure proper
penetration is having material we're going to do this it's exaggerated we're
going to do about a 50-percent overlap dragon that puddle the wire back throw
all right now what we just did there
that was what we talked about earlier just a straight gun movement reason I
don't like using this one on the heavier materials you can see we're not assured
of any undercut in here and proper penetration we're back here we did the
circular motion that we learn this you're carrying that whole puddle in
there making sure you got proper penetration between both your vertical
and horizontal piece
alright this is our lap world as you can see again circular motion that we've
been using fisher's you got about fifty percent penetration your top piece and
then your bottom piece for a structural world now we're going to do is show you
some of the common mistakes and how to correct them
let's move on to that
when you experience this
no penetration almost a raised crater that's too low of a gas setting or no
gas flow at all
check your tank pressure in your regulator setting went ahead just the
regulator to the settings in the manual and we have very nice spot welds what
this is typical to high voltage setting you can see the very large bead that's
here obviously blow through right there
so what you want to do is back down your voltage again set the machine back up
again for the 20 gauge so we went back set up the machine as per the chart
inside of the welder door is some very nice consistent spot-welds this is
typical too high of a wire speed you see your be very proud and domed up on each
of these actually is piece of wire right there
so you want to go back to your setup chart inside the welder door again
adjust for your material thickness so now we went back set up the machine as
for the reference chart you can see that we have very consistent low-crown spots
here now we're back to our door here we've cut out the corroded area there we
have some of our rust encapsulator treating some of the rust behind it and
we've taken a patch want to show you a tip one here to make it a little bit
easier so the panel's don't line up exact we saw the sheet metal kit that
gives you these doubler strips so 1-inch pieces of aluminized steel just in case
it isn't cut correctly or you need to shift something as you're going on there
alright as you can see we finished the repair here and what we've done is we've
shown you how easy it is to make well show you a couple little tips on there
but want to talk about is to performance in the value of these units what you're
getting is a unit that's equivalent to professionals that are out there about a
third to half the price the value of this is going to pay for itself on the
first job this store about 300 bucks about the cost to that unit on their
everything here forward is going to pay you back on this unit so by the eastwood
make 135 today start doing your own metal fab and welding saving money
