i know pics sucks and welds but that's what i havent right now.

Is that using the HF tig?

walter · « **Reply #2 on:** March 31, 2009, 04:22:11 PM »

yup , im waiting for new argon regulator and more argon..

be sure you're brushing that pipe off good when you go to making your real welds.
just cause that filler rod says itll handle some scale and light rust dont mean you want it too

that one bead doesn't look too bad.

Try to keep your ripples closer together, you're spacing out too far. You want to advance forward say 1/3 the width of the weld at a time. (that's what I visualize) - you don't want the ripples strung out real far apart or too close together. makes weak spots in the weld and the surface invites stress cracking later on.

Punch me in the damn face, you dont move in one smooth motion accross the part? maybe thats what im doing wrong.

i have never had any tig training but i used to play with it at work some and i came out with some decent stuff. i didnt do it for a few years and now i got my own and i cant seem to get it back.

dip, move, dip, move, dip, move
that is what i've always been told

Can we get any video of some of you more baller members. I would love to see how fast and or slow you are moving and your technique in walking the cup vs dip move dip move dip move

did that video along time ago for someone on hmt

SirDragsAlot · « **Reply #9 on:** April 01, 2009, 09:37:49 PM »

why are you using hf to weld steel? you use hf to weld aluminum. to weld steel and stainless, you use dc straight polarity. to weld aluminum you use ac reverse polarity hf

SirDragsAlot · « **Reply #10 on:** April 01, 2009, 09:39:11 PM »

i could do some video tig ing some stainless. ill see what i can do

Toysrme · « **Reply #11 on:** April 01, 2009, 10:37:40 PM »

harbor frieght, not continuous high frequency

walter · « **Reply #12 on:** April 02, 2009, 08:55:12 AM »

i got today argon + regulator argon (i was using a not gauge cheap regulator ;D).

this is pics with little brother's camera (i dont know use it good as my brother does.

Argon + new regulator..

ill begin to practice today , a bit more, how many Litres/minute do you use for welding? ill use today number 5 with 1.6mm (i dont know how the hello is english names of parts of tig lol)

slappynuts · « **Reply #13 on:** April 02, 2009, 09:12:44 AM »

Turn it down a little and whats your gas flow set at?

walter · « **Reply #14 on:** April 02, 2009, 09:30:58 AM »

it hasn'tt gauge regulator lol that's why i got new one regulator.

what gas flow i should set it up?

CSaddict · « **Reply #15 on:** April 02, 2009, 09:35:55 AM »

I run 18-20 on just about everything.

I concur with 18-20 unless you have your tungsten pulled way the fuck out to weld up a bugs asshole. ;D

To get a better idea of the proper heat setting look at the backside of the weld.

walter · « **Reply #17 on:** April 02, 2009, 12:15:55 PM »

ok, im practicing like 25-30 i think, trying differents flows and currents..

this is the last one "setup" i tried and looks ok to me..

what do you think guys, the pipe im using isnt ss, it's just normal steel.

ill begin to cut pipes for make log mani already

thx

walter · « **Reply #18 on:** April 02, 2009, 12:19:22 PM »

better pic of the last one..

malichite · « **Reply #19 on:** April 02, 2009, 01:54:47 PM »

How thick is the pipe you are welding? Also what are you cleaning the material off with? Looks like there is still something on the surface causing contamination. Turn the heat down a little more. I usually weld Sch10 a little over 4 and thin stuff like that around 2. These numbers make no sense to regular tig guys as they go by amps and we are stuck with this arbitrary numbers. Meh. Keep it up though. Youll get there. Practice on your starts with that machine. That will help a ton. Keep the tungsten sharp. If it ever sticks, pull it out and regrind it. Your starts will get harder and harder the more crap that builds up on the tungsten.

walter · « **Reply #20 on:** April 02, 2009, 02:03:32 PM »

2mm tickness , yes, i know , im not cleaning it, right now i have better use on starting. tomorrow ill tryng with sch10 already for my log mani. :yes: , i order already more rods since really i havent.

thx for your advice bro. :yes:

malichite · « **Reply #21 on:** April 02, 2009, 02:15:45 PM »

Yeah, clean your material really good. It makes a HUGE difference.

walter · « **Reply #22 on:** April 02, 2009, 02:25:57 PM »

yes, i know, i just was practicing for to know how works this TIG..not bad for what it costs..

tomorrow, ill begin to make my first mani

malichite · « **Reply #23 on:** April 02, 2009, 11:55:53 PM »

Here some motivation. This was done with the same tig. Keep practicing man. You'll get there.

walter · « **Reply #24 on:** April 03, 2009, 07:49:04 AM »

thx mike!

wow!! looks awesome! what rods did u use? what cup #? what flow/current setup?

walter · « **Reply #25 on:** April 03, 2009, 07:50:37 AM »

some progress...

walter · « **Reply #26 on:** April 03, 2009, 12:36:53 PM »

i have a problem right now with turbo, does 2mm thickness steel with works ok with log manifold? i have to extend it a bit..

confUsed · « **Reply #27 on:** April 04, 2009, 08:19:31 AM »

I built my log out of 2mm stell. It cracked a couple times, so I had to make some braces. After the braces its been fine

walter · « **Reply #28 on:** April 04, 2009, 09:46:24 AM »

oh yep, ill brace it of course thx

i think i was using a high flow setup since you use cfh and here we use lpm, so if you use 18-20 cfh, i was using 18-20lpm, in cfh is i think more than 30 ,kinda high.. ill try with 9-10lpm next week. :yes:

walter · « **Reply #29 on:** April 07, 2009, 10:11:13 AM »

fucking hard to weld to flange...

to got 1.6mm ss rods today and im practicing today ,well really im making the log mani and it's hard to weld good to the head flange..i dont get it get moves forward.. $:-\$

i was checking some vides last wee 70Âº for toch and 20Âº or so for the rod..any input..
