No help? Let me expound. I am thinking that a spool gun on only a 110V 140A Mig machine would be too limiting for Aluminum welding. Not enough power for 1/8 or above and not optimum for much thinner material. I would end up using TIG for anything aluminum and hardly would want to use the Spool gun. ...

Yes I have watched several of Jody's videos. Good stuff.

I own a HF Titanium 140 and a Primeweld Tig225. I have used the Mig alot, haven't used the Primeweld yet.

Hello, I am John and a beggining MIG and TIG welder. I have done stick and gas many moons ago but just getting starting in the MIG and TIG world.

My applications are mostly hobby and toys.

Hello, First post here.
I picked up a spool gun for my HF Titanium 140A welder. I also have a Primeweld 225 Tig AC/DC. Is there any reason to keep the spool gun for the 140A welder? I was thinking of returning it and saving the money for better things.
