hey guys welcome back to wall comm so in a previous video we did some flux core on
what I considered to be thin gauge material and it was eight inch now in my defense I'm an iron
worker eighth inch is pretty damn thin but the comments section went a little haywire some of
y'all got blew out and said that that's not thin gauge material so hopefully today I'll be able to
redeem myself a little bit I have some 18 gauge material or o5o and I reached out to our good
buddy Jerry masters and let's elect arc okay this is our second pass I did it a full weave to find
out his recommendations for thin gauge sheet metal so today we're gonna be using some 700 GS it's
specifically designed for the 115 applications in your garage so you can use this on body panels and
things of that nature of 22 gauge material all the way up until 3/16 and it works well on galvanized
so for those of you that we're asking how do I walk galvanized material try switching this
wire and you know get back with us on the results so let's go ahead and get into it we're gonna run
about 150 inches a minute on wire feed speed and 15 volts so we'll do a couple laps t-joints and
then maybe a little bit of a thin gauge sheet metal for y'all 18 gauge to some thick material
which is a 8 inch so we'll try to do a lap joint on that see how it turns out it's good get into it
[Music] ice other than the the small wormhole that I got here from hold my contact tip to
work distance to close initially on my tack everything else went pretty good very smooth
running wire very surprised that we could do that on 18 gauge with flux core let's go ahead and
run a T joint configuration same two two piece of eighteen gauge and then we'll do the thick to thin
right after that all right so as you can see I'm moving a little bit faster than my travel speed
that's because the previous coupon that I did I didn't account for that I ranted like I normally
do and I just kind of blew a hole in that piece so this is my second second attempt here and go
through moving a little bit faster just watching the puddle make sure it's wetting in you'll notice
that I point a little bit higher up on the vertical leg and that pit that's because this
stuff runs a little bit more fluid and it likes to Sag a little bit so just point a little bit higher
on that vertical wall moving a little bit faster you shouldn't have any issues you can also see on
the back side camera that you know we're getting amplify nitration we're not blowing holes in this
stuff overall it's a really good running wire alright so went in there pretty good yes it's
pretty smooth overall you got to move a little bit faster than you typically you think you should
didn't get a obsessive amount of penetration on the back we got good penetration through
and through as I said you want to make sure that you're moving quick just the second piece that I
did the first one is here I blew about a half inch hole in there traveling you know snow is slow like
I normally would so you just got to pick up your travel speed just a little bit and you know the
results are much greater that way let's go ahead we'll do a thin to thick on a eight inch and 18
gauge alright so we have the thicker plate on the bottom thinner plate on the top so that's
the eighth inch on the bottom 18 gauge on top anytime you're doing thick to thin you want to
try to concentrate the majority of your heat on the thicker part and just kind of wash that weld
up into the center component so as I was going through there I was just washing the edges of
that puddle right up onto the 18 gauge give me a nice good tie-in everything's nice and clean well
you know the wire flowed very smooth you're gonna notice that once again I'm traveling a little bit
faster because if you hang out too long and watch too much that puddle over you're gonna
start developing openings right there at the toe of the weld and you want to avoid that at all cost
so just watch your travel speed watch your travel angle and you shouldn't have any problems alright
so hopefully I was able to being myself by welding on some gauge material instead of eight-inch as
what's you know that's what I considered thin but apparently I was wrong so hopefully that helps you
guys out for those of you are asking how to weld on thinner material with flux core so if you have
a 110 machine at your house don't feel defeated because you got some bodywork that you want to do
you got some pans you got to put in the old car whatever you're you know you're attached to some
new floorboards in the hooptie you shouldn't have any issues go get you some 700 GS you can run it
on any or 110 machines at the house you shouldn't have any issues whatsoever remember watch your
travel speed and travel angle and you shouldn't have any issues hope you guys enjoyed the video
I hope you learned something a long way and until next time make your world better than your last
