i saw somewhere on this discussion that someone converted their ac/dc stick machine to TIG. i did not know that was possible, but would sure like to know how if someone could tell me. also does it have to be ac/dc or can it be done on ac only stick machine?i have a miller thunderbolt ac stick welder and it is great for my farm use, but a tig would allow me to expand my capabilitys. any help would be greatly appreciated!

HAYBINE...............WELL YES IT CAN BE DONE IT IS A CONSTANT CURRENT MACHINE.............IF YOU USE A TIG TORCH, A GAS INLET, A REGULATOR, A BOTTLE OF GAS...............YOU CAN DO SCRATCH START TIG ON MILD STEEL, STAINLESS, AND ALUMINUM........ NOT WELL BE ADEQUATE ENOUGH TO GET YOU BY..............YOU WILL HAVE NO LOW END MOST STICK MACHINES (BUZZ BOXES) HAVE A MINIMUM OF 30 AMPS CURRENT OR 40 AMPS MINIMUM DEPENDING ON MODEL ETC.................. YOU WILL HAVE NO SLIDE AMP CONTROL NOR WILL YOU BE ABLE TO INSTALL A FOOT PEDAL...........BUT YES IT CAN BE DONE............... IT IS SCRATCH START SO THE TUNGESTON'S GET CONTAMINATED ON A REGULAR BASES......................ROCK..........[email protected]

Sorry, I have to disagree with Rock on this one. Haybine for this to be successful you need a machine with a DC side. As Rock stated you will scratch start the tungsten. On the DC side you will be able to weld steel and stainless steel. It is definately not as easy to TIG weld with this setup as it is with machine that is equipped with a remote current control. Now I wouldn t even worry about trying aluminum with such a setup. To weld aluminum you want to use AC with a high frequency unit to help stabilize the arc. Problem with aluminum though is that it builds up heat in the entire part quickly and you really need a remote current control so that you can slowly reduce the welding current to compensate for this build up of heat. With out this current control you will lose total control of the weld puddle. If you over heat an aluminum weld it is almost guaranteed that it will crack.Last edited by Dan; 03-12-2003, 11:03 AM.MigMaster 250- Smooth arc with a good touch of softness to it.

HAHAHA.............DAN.............YOUR RIGHT ABOUT THE ALUMINUM THING, YOU DO NEED HF...........SORRY MAN WAY TO MANY THINGS GOING ON AT THE SAME TIME...............DISREGARD THE ALUMINUM COMMENT...........I WILL TRY AND GET BACK TO EDIT IT AS I GET OTHER PROJECTS FINISHED UP....................... HAYBINE YOU GOT SOME BUM INFO FROM ME THIS TIME...............ROCK[email protected]

Aluminum was welded with DC TIG long before they were able to sustain AC TIG arc with constant high frequency, had Square Wave AC welder or had AC balance control. That is short list of what modern TIG weldors expect Aluminum TIG welding machine to have. Still possible to TIG weld aluminum without modern "necessities" but not considered practical. It's also possable to swim english channel but not practical or even possible for most people.Last edited by Guest; 03-12-2003, 12:04 PM.

ROGER.............THE LAST POWER MIG 300 I SEEN THE FAN BLADE WAS TURNING SO F AST IT LOOKED LIKE A BOAT MOTOR PROP........THAT SHOULD GET SCOTT GOING..................ROCK[email protected]

Power mig can't swim no matter how fast fan turns. I thinks they weld ok if color doesn't clash with your decor.
How did they get side tracked to MIG?
In my original post on this topic I mistakenly put DC MIG in first sentence and edited it to correct DC MIG within 5 minutes. This darn computer displays what I type not what I meant to type.

I would have to agree with Dan on some of his reply(dc mach&ac with high freq.) But dissagree about ease and quality of DC straight polarity for tig. I have x-rayed high pressure tubes with gas,diesel,buzz box machines on DC straight polarity. revpol.

And by no means is a buzzbox TIG for X ray quality work. A buzzbox tig is strictly for non critical work.MigMaster 250- Smooth arc with a good touch of softness to it. Good weld puddle wetout. Light spatter producer.
