Hello again . I have a question. I know you can hook a tig torch to a stick machine but was woundering if you can hook one to a mig machine like a miller250? If so how ?
Thanks

Sure you can hook TIG torch up to a MIG welder but Best case you end up with very hard to use welding system. Might not be good for your welding equipment.
MIG welders are Constant Voltage welders.
TIG and stick welders are Constant Current welders.
Each Volt/ Amp curve is tuned to make welding easier for that welding process.

Why sure you can "hook a tig torch up to a mig machine".

Gonna play heck pushing that little wire through the collet at the proper speed though.

Bottom line.

Not going to happen, mainly for the reasons outlined in the previous post.

Hi All,
I just found this great site and wanted to get in on this question,

I havent purchased a Mig yet but I was wondering about using the Tig handle with cut off "sticks" of mig wire, I was figuring that I can get in close to do some "spot" welding on AK47 receivers, some of the rivet holes are off and I just need to get them partially filled instead of a complete weld up and re drill.

I havent mig welded much except for using a friends spattering flux core Easy Handler 125; it made such a mess on an HK receiver I knew I needed to go Gas.

Thanks in advance:

No!!! The TIG process uses a stick of tungstun in the torch body instead of the weld metal. Ideally, the tungstun is not added to the weld material. The TIG process will work quite well for your needs, but it won't work at all as you have outlined the procedure.

Thanks Wyoming,
I have a lot to learn and I wish I could afford a Tig right off but you know how that goes.


I need to read this site to death.

Night.

With practice on scrap, always a good idea, you should be able to MIG the holes. Lots of people make "spot welds" through punched holes in auto restorations with a MIG. I would be more concerned about the compatability of the MIG wire with the reciever and the heat effects, regardless of the application method.
