Posts: 2888 (03/16/06 6:42 PM) Senior Member Reply Quote More My Recent Posts Message Me Connection Blocking Invite Ignore User's Posts	I am wanting to convert my arc welder to tig...I have a 250A ac/dc reversible supply. From what I can tell all I need to do is get an argon/co2 tank, flexhead torch with reg., flow reg. for the tank, and the dinse to attach the tig torch to my rig and then run it all as DCv....does this sound right or do I really need to buy a conversion kit like whats on tigdepot.com? yes I know I wont have a foot pedal...dont care. The kit is 260$ without the tank...I can buy all the parts mentioned for $250 WITH the tank if I do it on my own. does all this sound right?

Their Argon tanks go for $60 by themselves. I've been thinking of the same thing for my Lincoln 230/230, and I know Sawsall did it before he lucked into a HF setup.

When useing TIG you control the heat by the foot pedal. It is not like mig where you can just set the heat and weld to do it right you need full control of the heat at all times. jason

Sucks, cuz I wanted to do that too. As far as heat- I suppose you have to guess, and try a short run before raising or lowering, and hope you didn't do much damage.

You have to use the judgement & practice to determine heat & set it on the machine... General rule I used was the thickness of metal was the amperage I used... then adjust from there... while welding if you burning through move faster or stop & turn down the heat... not hot enough, move slower or crank up the heat... You don't need high frequency unless your going to weld aluminum... you will have to scratch start.... You can find tig torches on ebay... But you can get as good of deals at you local welding supply... sometimes they will have used stuff... Tell them what you want to do... They will have the tank, argon power cable, torch, tungsten etc I leased my tanks...
