so welcome to well.com today we're going to do the flux core basics with frankenfab bob
frankenfat bob has done some flux core work but non-gas without the gas non-gas so we're
going to do it with the gas today and we're going to use the everlast multi-process lightning
mts275 and we're going to use 7525 and we're going to use right at 20 cfh on the gauge
and the wire we're going to use is the bowler diamond spark 50 trc o45 seamless flux core
welding wire with an aws spec of 5.36 so this is a a very very basic course to get the beginner
started and understanding how to weld flux core so what do you think about it bob i'm
excited man uh we've done like you mentioned we've done a lot of little little mini uh
flux core things we've got a little small buzz box in our shop and we do little hobby
welding things but i've never done big wire we're using 0.45 wire and shielded gas as
well so i'm excited to get out here and test some coupons out and get a get a better knowledge
for some flux core mig welding so i'm gonna show the settings on this everlast multi process
you know lightning mts275 machine it's a multi-processed machine so it'll tig stick and mig so we're
going to do the mig process today so you see it's got a selection up here you have mixed
steel c25 but reason why i'm using the mix dlc 25 is because we're using 75 25 today
with the flux core wire that we're using just carbon steel you don't really need a lot of
pre-flow it's not like you weld stainless or any hassle or anything like that so we'll
just use go up to one and then we'll go to the next setting and it's the wire feed speed
to start at 60. we'll start there upslope we i got up slopes i'll go up to it goes up
to or 1.010 so i'll go we'll try we'll try three so then we'll go down to the burn back
which i like to set to burn back about halfway [Music] so it goes up to two so i'm not even
gonna go halfway i'm gonna go a quarter i'm gonna go to point five so there's point five
on the burn back so the down slope i'm gonna go back like i said it goes all the way to
one and i'm gonna go to five so we'll go to the next one wire feed speed at the end we'll
keep it on 60 go to the post flow since we're not like i said we're only welding carbon
steel i'll set it on two and then of course your abductance i like the inductance about
35 so that's what we'll do on that
and of course we're on 2t so we're going to start off with with a wire feed speed i'm
going to start off about 360
360 and then we're going to start at 22.5 volts and what we'll do is we'll we'll go
to 22 and a half and me and bob will burn some burn a couple passes or one pass and
bob will burn a pass and then we'll talk about it but we're going to try to we're going to
go down on the bolts and same wire speed and we're going to go up on the bolts with the
same wire speed and we'll compare it so as you can see we got our 2 8 36 3 8 stick plate
with both 30 degree bevels with a 1 8 landing and at 332 gap bob wants a 332 gap so guess
what bob gets 332 gap so we're going to go from there and um just like i said he's going
to push it pushing it or pulling it whatever you do 15 degrees with about a 5 8 stick out
5 8 stick out yup i'm going to run some of these uh i'm going to run this first set of
passes i'm probably going to drag this backhand and we're going to get it tacked up and i'll
i'll pull it this way but i think this is a good start for uh anybody looking to get
into flux core if you know mig this is a very similar concept but i don't know much about
flux core so this is where we're getting started and this is gonna be a good process for us
[Music]
so you can see frankfort bob ran that route and it looks pretty it looks really good and
consistent but we'll find out how consistent it is when we turn it around look at the root
well here it is so he started out really good of course that was his tack up here so so
he started out really good going really good going really good going really good did wham
something changed and what i can just figure out what do you think bob just instead of
instead of putting a wire dead in the v-groove you might have just built up on the on the
on the bevel yeah and then it didn't break it down as well i agree i didn't i didn't
keep that penetration and i must have stepped off somehow and then i stayed on top of uh
my impurity and i carried it all the way to the end of the plate so so they live and you
learn yeah right so just like bob explained before you know this is just basics for flux
core welding so this is what this is what happens this is the basics you know that you
want to learn out there in the audience of what to do and what not to do don't do this
[Music] so so as you can see bob ran a nice filler pass in there it filled in the sides
tied in real good had little babies here that he knocked off with a grinder which is fine
but both the sides are tied in really nice it looks really good we turned it up a little
bit we turned up the bolts like 10 volts we started put the root in at 22 and a half or
22.5 we put the fill in at 23.5 but kept the same wire speed at 360 for the route and the
field it looks really good bob for someone that said you don't know how to flux score
weld yeah it looks pretty good thanks and another thing is that well looks so good and
so tight it's like my welding cap them como caps they're like i mean they fit good look
how good this thing fits it's nice it's slick nice and snug and slick reverse i like it
reverse your ears they're nice man so uh shout out to como thanks for the hats and anybody
out in the audience ever ask about what kind of welding cap you should buy come hoes of
cap to buy get them local welding shops approved yep so we're going to go on to the to the
first pass of the cap we're going to leave it on 23 and a half volts are you going to
go up a little bit what do you think let's try kicking it up a little bit and we'll see
how it runs and then we'll be able to adjust it we'll have a good idea of what our temperature
settings is and and then we'll determine whether we need to come up or down for our last cat
pass so we'll go to 24 on this one yes sir 24 volts and leave it 360 wire speed let's
do it all right let's do it fire no
[Music]
[Music] look at that slash
that's my first flux core slag peel everybody
so as you can see we turned to turn the volts up five so we're this is at 24 volts and um
360 on the wire speed and come out really nice you might threw a bb here and there you
take a grinder wipe that off but as far as as far as the overall cap looks the profile
looks really good and another thing is this is why we like these bowler products look
at the flux it falls right off in one piece so that's a good thing and that also tells
you that your heat your angle and your speed is right on point because that's what happens
when it when everything falls together your flux falls off just like that and a few beginners
out there just like bob walked in here and said i've hardly ever done any flux core welding
so this just goes to show an experienced stick welder you can make him a really good flux
core welder and that proves it right there i dig it i like it bobby did a really good
job i appreciate it man it uh you know for anybody out there that's just getting into
flux core over mig welding it has a lot of similar characteristics you know it's still
you know a mig gun but it also carries that same characteristics like a stick welder and
has you know slag peel type of thing
it's different it's another process i really like it i really appreciate paul you're bringing
me out and let me try this anytime my pleasure obviously i still got some more practice to
do i'm not going out and selling flux core weld jobs just yet you know i definitely need
some some more practice obviously got to work on my roots too but i'm excited i'm excited
for the new process i'm excited to get out and try it in my shop and in the field and
then you know end up selling some work in the future with it
[Music] you
