Welcome to the extreme TIG Channel for today's video I'm going to show you walk the cap
technique, especially for beginners so we're going to start with a basic step it's on a plate
try to remove the mill scale and drop some lines they can be a different width
and for a cup, I'm gonna use cup size 8 tungsten 1/8 stick out up to 10 mil so the
basic and most important thing here on a plate is learn how to roll that cup how to walk the cup
with the tip of the tungsten then you're gonna stretch that puddle from Line to Line you don't
want to cross that lines so you can use different techniques here, for example, a free hand
but the main thing is to keep that puddle in between the lines that's how you're gonna learn how
to control that puddle you can also change, try a different size of Cups 6, 8, 10, 12.
play with the settings, play with your amperage, you can go faster, you can go slower, stretch, go wider
steps, bigger steps, try to switch different filler wires 3/32, 1/8, 5/32
that's how you're gonna learn that's how you're gonna control the puddle
and to maintain the same straight edge on both sides, this is how it should look
like, okay now let's go on a pipe so once you do want to play it, try to do it on a pipe on the root
pass so you can you can use a couple different techniques, here you can switch on a cup size 6
that's what I like to use sometimes so you can actually wiggle that cup inside the groove it's
a really fast and easy-to-put root, so I'm gonna show you an example here on a six-inch pipe sch. 80.
this is how I sharpen my tungsten it's in the field, it's not recommended usually we use the
a bench grinder with the diamond wheel here I gotta use an angle grinder, okay as I said cup 8
tungsten stick out up to 10 mil , cup size tungsten1/8
okay this is a little example of the root so I got a cup 8 here, we are actually
wiggle, walking the cup on a root with the lay wire technique or a constant feed
with a smaller cup, you can actually go inside that the bevel and
you just wiggle it's easier it's faster this is one of the advantages of walking the cup
on the root, you can really weld that pipe fast
smooth as you can see from the outside you can see that you actually walk the cap on a root pass
just by looking at that pattern that is from the outside that outside appearance
that's how we know, that's walk the cup, okay so for a hot pass the same thing walk in the
cup, walking the cup gives you better control makes welding a little bit faster than if you freehand
for example, you know for a free hand you have to go slow, you have to go side to side motion
with walking in the cup, you actually gain better control over your weld puddle
and it gives a little bit more advantage
as you notice the cups are the ones I'm using in all my videos pretty much they're pink
the reason why they are pink because they're made from alumina oxide that's why they got that pink color
I don't know if you know about alumina is a high temperature non-conductive pink ceramic material
and, it's mass-produced which is why alumina nozzles are less expensive and
then the other one they're made from different materials, those fancy ones, so basically walking
the cup is as you can see here is actually like, theoretically walking the cup should be
a technique that you actually walk in that cup on the material that you deposit in
but we like to use the term walking the cap on the root , hot pass, fill and final pass so
the main thing with walking the cup I wanna I wanna on a final pass or on a cap is an inclination
the inclination of your tig torch inclination of your rod filler wire, is there any particular
exact inclination!? No, inclination changes you know is especially if you're in the field so
it's always vary you go from extreme angles to like 15 degrees 30, 33 so it doesn't really matter
that's why it's really important to catch some Basics at the beginning so you got a good start
especially as I said if you're a beginner that's why practice on a plate or on a angle
iron or something like that you know you just try to get your hand familiar with it.
know to that motion to that walk in the cup what I think usually What It Takes uh it takes
six to seven months of really constant practice to really be good at walking the cup technique
and this is the final product with the walking the cup as you can see straight edges
on both sides of the weld bead, equal steps and the final product looks, good and that's one of
the advantage okay now we're gonna show you a cup size 10. what is the advantage of the different
cups, different that just means more gas coverage for that weld puddle for the weld Zone
also with a bigger Gap also with a bigger cup
you can have that wider step you know you can stretch that for example cap here I'm gonna do
it's gonna be wide, which wouldn't be possible with probably with a cup 8
that's why on big heavy walls on heavy Pipes big pipes you want to go with the bigger nozzles
usually, guys ask me if is there any difference of or is it important about a gas flow that goes
through your torch? Yes it is, of course what I like to go with 20
25, 30 sometimes it all depends on the form the pipe from the Weld, from the material and
the application more gas cleans your weld gives nice good protection
and especially when you're running hot
so as you can see here the control side to side motion with The Walking The Cup
tungsten always got to be a Sharp that's one of the important things
the sharp tungsten gives you good really good control over that weld puddle and
the rest is you, the rest is your how focused you are while you're welding
you know there are lots of things that can be you can be distracted especially where when
you're holding that torch close to that weld it's getting hot you know your tip of your
fingers, if you hold that filler wire too low you can start burning your fingers
and this is one example just want to show you the walking the cup is actually the motion of your arm
not the wrist, the wrist is the motion when you do on, when you do wiggle on for example on
a groove, on a root pass, when you wiggle inside that Groove, okay another example is cup size 12.
this is for, this is 16-inch pipe
heavy wall as you can see that groove here, that bevel is big, wide, that's my bigger bigger
cup, it's perfect, lots of gas going through that cup so it's gonna cover your weld zone
a little bit bigger than 10 mil
so the big pipe like that can be welded very, very fast
especially if you use 5/32 and you can continue like from once you start to fill
passes you know fill to flush and you can do cap pass with the cup size 12 as well
160 amps on this cap High amps you know gives you more control you can go
faster you know with the big with a big cup you can have a wide step you can go wide
with your each step so which uh which will help you you know to move from
especially from some positions, they are really uncomfortable and awkward especially at the bottom
it'll help you you know to start moving faster and going up all the way to the top and that's
it pretty much uh as always as I said you gotta burn to learn there's no other way around guys
I hope this video is going to help you you know , to sharpen your skills to
get better in Walking the cup technique and I hope you guys uh enjoy it like it uh give
a thumbs up , always feel free to comment send me an email. I"ll try to respond if when I got
time usually I do and that's it take care guys play safe and see you in the next one
