welcome to well.com today we're going to do tig welding for beginners and frank and fab
bob i'm going to use as my apprentice but bob's got a pretty good handle on what he
needs to look at and how he needs to control his wire and everything he's a tig welder
but just beginning so we're going to get him up to speed today and get him going on this
thing so what i'm going to do there's i got three different tig rigs and consumables on
the table here because i'm i'm going to explain every one of them and i'll put one together
that we're going to use for bob to demonstrate some t-joints or a t-joint and a corner joint
what do you think bob i i'm excited man i'm ready to try it i am not a tig welder though
but i do have a little bit of some practice we have a little small rig at the shop but
it's pretty uh it's pretty different from out here we don't have any flex heads we don't
have a foot pedal uh so i'm using paul's knowledge he's gonna teach me how to control that filler
rod and he's gonna he's gonna help me with getting the basics of this stuff down so at
least i can uh have a better view of what's going on bob will be a tig welder by the end
of the day that's the dream anyways well i got like i said i have three different tig
rigs here and this is wp9 everybody knows this as a mini rig a little cutie and she's
a cute little thing isn't she and i have a 17 f v anybody wants to know what fv is which
everybody does want to know and if they don't know it f means flex and v means valve that's
simple yeah which i don't have any of that in my shop either so you will it's kind of
cool to check out so then we have a 26 which is a bigger amperage welding tig rig and it's
a 26 f why is it a 26 f bob because it's got a flex but no v no valve simple as that simple
as that so what we'll do is i'm gonna go ahead and assemble assemble the rig that we're gonna
use that bob's gonna demonstrate with swivel head i don't have one of those either so i'll
take take the cap back off this and go to assemble it so what we'll do is we're going
to use the gas lens a medium gas lens and of course an insulator so the rig insulator
and the gas lens
so what i'll do you put the insulator on on the gas lens screw it into the tig
rig put in this is a number eight cup
c8 on it screw it onto the gas lens just finger tight you don't have to take a wrench or anything
just spin your tight then we'll insert the collet 332 collet for 332 tungsten and put
tungsten in it
you have three different selections for the cap back you have the full-size cat-back which
we're going to use because we have the full full stick of tungsten and i'll assemble
it it's that simple then we have the shorter cap back where we have the shorty cat-back
out in the field all welders call them buttons remember that butt button half rooster tail
full rooster tail so we're gonna get started let's do it let's get it welded out so you
see we got our plates tacked up this is stainless so he'll fuse this one with no backing gas
and then we have a corner joint carbon that we're going to use the bowler 70 s2 332 diameter
with aws spec of 5.18 and then he's going to demonstrate the same filler wire 332 on
a t-joint we'll get started doing that but look at that tight fit that's a nice tight
fit so we're these como hats that we're wearing tight fit nice soft bill durable 100 cotton
great hat just give a little shout out to como we really appreciate your products appreciate
it so you ready to do well now let's do it so i'm going to show you the setup on this
everlast mts-275 multi-process machine we're going to fuse some stainless together some
14-gauge stainless is what it is so we set the machine up for 34 amps and so the pre-flow
set on point two which is two seconds 20 for the starting amps 20 for the end damp 2t control
foot pedal so the up slope i'm going to leave that zero and the downslope i'm going to leave
it at zero so what we're going to do is fuse these two together and see how it runs you
ready all right paul so now i touch i mean i turn my gas on then i touch and lift off
or touch gas lift off yep touch first then gas then lift down foot pedal then lift up
yeah all right
a little too fast point the rig straight up point it straight up and down there you go
now roll with it just fuse it just fuse it just go real slow and steady i don't even
have to weave it huh nope go down a little bit lower to your puddle there you go and
just fuse it all right is it hot enough i mean it looks like it is doing good it looks
like it is in the back here
looking good there bob oh thanks man yeah i could tell you already from the start just
from being in my shop i already started doing it wrong i was trying to like make some beads
and right yes i i was going to a little bit yeah i see it let the puddle widen a little
bit there you go there you go i need to focus more
yep
what do you think about it i like it i definitely need to work on uh consistency
my favorite word
yeah you really don't have to oscillate it much you don't think just hold it you know
yeah so bob you see where you started off and then i you so i had that wide angle right
so you started rolling with it a little bit it looks good but then i told you to point
it point it straight down into it pretty much and that's where you picked that up yeah started
really rolling pretty good but too fast and kept going pretty fast and i said slow down
a little bit yeah i see how i thinned out a lot then it got thin a little bit and then
it got a little wider when you slowed down and then at the end of course that's my fault
get off the gas i mean the pedal yeah so i should have took my foot off the pedal versus
lifting off the plate but it's all right that's your first plate i'm sure the next one will
be better but just like i'm saying you show you know showing the audience about getting
started tigging kind of self-explanatory with with the with that fusion oh yeah i mean well
with you explaining it because i i would have passed that so we're going to go the t-joint
now so this is carbon so what i'll do is i set it up on 85 amps which should be nice
and warm but what i am going to do we don't need any really a long post flow like you
do on stainless or titanium or anything so i'm going to lower it down to point to point
one
so the down slope i set up zero up slope set on zero no pulse pulses off two t control
foot pedal so the end and the start are both on 20 amps so the pre-flow i'm gonna go to
point one second so set it on point one and now we're ready to weld the t-joint [Music]
[Laughter]
get it nice and hot and you can always just dip the wire you know what i'm saying just
dip a little wire move dip and move or you can just run right over the wire depending
on how it is you know yep
there you go just oscillated a little
bit
i'm losing it man what are you losing i don't know i feel like i need to get hotter feel
like you need a little hotter all right let's pull out then hold on another weight yeah
come on out
pedal there you go let me turn it up just a little bit what do you think it could be
me no let me turn it up a little bit
how that heat now seems a better no better good [Music]
yeah with something like you're doing i just go ahead and just dip it get it hot dip it
move dip it move you know what i mean yeah i think you're right i just gotta dip it like
that huh yeah so that's part of my major problem is dip and i have a i have a dip issue
yeah there's all kind of different techniques every welder is different so they pick up
what they like to do or what works best for them you know right i mean you could turn
that thing up to 150 and just lay the wire in the weldment and just run right over it
and it'll come out nice and slick or or you can just dip it you know and manipulate the
metal around to uh tie both sides you know
so there's a couple different processes with how you get your filler onto the material
right different scenarios for different techniques you know yes sir you know it's always good
to learn all the techniques so
after we welded the stainless we went from 34 amps and we went to 85 amps for this carbon
t-joint and you can see he started out a little trouble you know barely getting the wire in
there and getting the puddle wide enough and then he picked up the pace and and the puddle
started and the material started picking up the heat and he started dipping the wire so
i think i think bob's a dipper i need i need definitely need some dip in practice for sure
um yeah he's a dipper so he was dipping the wire going along pretty good and i guess he
got out of comfort zone right here and forgot to dip a little bit and didn't move enough
metal around so practice practice practice practice practice right so anyway he finished
out pretty good but i mean for a beginner i think bob's doing very well but if you for
the audience out there that does the same thing that's why i'm telling you you know
get it hot first and then dip the wire because a lot of beginners are people that that aren't
used to tig welding yeah especially me to get it hot and run right over the wire yeah
i had that i had that issue right here i got i got in and i started to set it i thought
it might been hot enough and i tried to get some wire in there and it just balled up on
the end of the on the filler and obviously that's when i found out i was not hot enough
uh ball helped me adjust and we got set up and then it started to lay in there nice except
for that uh that little weep hole there i i left that on purpose i didn't know you left
it he took the drain hole i left the drain home [Laughter] but that's that's part of
being a beginner you know what i'm saying so yeah but as long as you progress every
time after you pick up that tig rig it progress better absolutely that's what it takes you
know absolutely so so what we're going to do next is we're going to go move to the t
we're going to move to the corner joint now i'm going to turn him up about 105 this time
and see if he really smokes it in there this time so third chance is the charm now i know
you got it in you bob come on i know it's gonna work i just know it
slow down a little bit there you go keep that pace right there put the wire in there there
you go roll with it now
looking good bob thank you sir i told you gonna be a tig welder by the end of the day
looking good
nice even speed
looking good
so bob looks like you're getting the hang of it started out you know this is at 105
amps so started out going really good keeping up the good pace the consistency the profile
looks good slowed down a little bit at the end which was good getting a little hotter
sped up slowed down made you made the end come out really slick and pulled out yeah
thanks man i see a little spill off a little bit you know that's all practice right exactly
i mean 105 amps is fused well we ran wire this one so you run right over the wire it
looked really good great penetration
great penetration a little push through there but it's just practice but anyway we're going
to compare all of them and just like you know starting off using the plate
you know you had a couple little hiccups yeah not big ones but just improvements then we
went to the wire
and just like i said you had a couple hiccups and approved then you went to the third one
[Applause] and really improves but just like you're saying you know just all practice next
time we'll have to go with like 1 16th wire or something yeah yeah that's probably what
was wrong that's why it's got a little bit overspill but you know this is all practice
so i think bob's gonna make a really good tig welder i appreciate it man i i appreciate
the help i wanna uh i just need to work on my my hands and my feeder you know like getting
that hand movement i know it's all you know muscle memory over time and you know it'll
come to me i'll get it for sure
