i started on 230 the lowerd to apx 180. ac balance 95%en 60Hz freq. 120Hz is a good all around seting, i use higher onli on 1 mm and evan than mostly if its corner joint. 1 mm is hard on low Hz. foot control. not a must but helps alot!!!!!! try 180 190 when its cold and u can lower the amp for the b...

the position of the pieces is relavant to your comfort. do on verticl and on horisantal.... and one 45 :) .....see what works for you. no one true way. as far as filler i would stay with 2.4 if u have better beeds on longer runs try to go extre slow at first, dab filler only to keep the puddle stabl...

the reason u dont want gray in the weld is because u cant always tell if it wiil clean up. aim high its ok,
its what i do anyway. and in some jobs i loosen up.

i always keep 5 elctrodes sharp and ready but i think he ment what can to not contaminate in the first place.
try to set shortest stick out u possibly can and be able to se the tip when u weld.....

when u dip youe tungstan in the puddle it changes the way the arc flows trough it. so insted of focused arc it spreads al over and u have to put more amp which heats up the metal way more than you should. as jody says in on of his videos "in order to get better, get as much "under the hood...

Yes its supposed to replace purging. A tin of the stuff is cheap so I thought I try it out that's all otherwise I would have welded like you say. In this case its an r&d item for use in the shop, not for customers so the finish really does not matter. But its good to explore new ideas and techn...

had the same problem this week. 15 mm plate to 3 mm tube. couple of things i do before i weld (learnd from weldingtipsantricks.com ). 1) dry run and position so u can run all the way stedy. 2) try to move 3 mm every second. 3) focus the arc on the thick part. if the thick part is the verticl one the...

whats does it supose to do? replace purgging with argon? for somethin this size if i wasnt into purgging i would weld from the inside (more important to the surface the food touches, and clamp a piece of copper or aluminum from the other side. seems to me like the mith of aluminum welding rods nice ...

i just bought a tig 200 square wave brand new ,problem is im welding .060 square tube even at 10 amps it blows a hole the size of a dime just tapping the foot control even with 15 - 25 cfh of argon .anyone have this problem ? had the same problem once with an old welder although i bought mine used....

thanks for the tip noddybrian. ill try 75% ar/ 25% he i hope it will work. btw i used 5356 filler wire i dont know what the part is for, it a welding job i do for a big fab shop, they work with the big name companies so i didnt ask. i get about 5% of the welding jobs they have, they do almost all th...

for argon its ok. but helium 240$ a tank??? i figuerd it has to be atleast double than argon but not 240. well If its the same over where you are than i must be mistaken........

If you have access to a cylindet of helium to mix with your argon you will achieve a hotter arc and puddle so you can weld easier and also be able to introduce more cleaning action. Jody shows how to do this and there is plenty of discussion on the forum too. Search helium. i bought a small cylinde...

thank you all for your answers.
the plate and the suports are 6061 and the tubing is 6063.

my welder is vary borderline on this thick aluminum so i'll probably go for a 350amp one.

hello everyone first time posting here so first of all thank you jody for this exelant site and forum, learned alot. sorry in advance, i dont know how to explain in short..... im from israel and have been welding with tig mostly stainless steel. from time to time i welded some aluminum mostly up to ...
