AC/DC Buzz Box with Tig Gun

admin

I have some old welding equipment from a past neighbor who was a career welder. Two tig torches and a tool box full of tungsten, cups and accessories.I used to work at a place that tigged SS all day long with small buzz box machines made for tig.Can't I just get a bottle of argon and hook my tig torch to my stick machine, set the polarity on AC, use the lift tig method and weld steel and SS?Thanks

Reply:I do it on my Dial-Arc often and used to do it on my Miller Thunderbolt AC/DC machine.One of the pipe welders where I work does it way too much. He can't do delicate work requiring a foot pedal as he isn't use to having one. The older guy tells him he needs to use the foot pedal to get use to it. But he is young and don't listen.

Reply:Get your self a bottle of helium, and you can do some aluminum welding with a Tig rig on DCEN. With out a foot pedal you can't weld very long with out stopping, but it can be done. Here is a short lap joint weld I made on some 10-GA aluminum, without a foot pedal.

Reply:Thanks for the good info. I will be buying a small gas cylinder soon and testing it out. I'll post pics of my discoveries.....

Reply:I've done it on thin aluminum on DCEP with argon as an experiment - but you have to upsize your tungsten about 2 sizes due to it taking so much heat.  The 1/16" tungsten exploded It leaves a very wide cathodic etching band - but it works Dave J.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:Originally Posted by kctgbI was wondering how you weld aluminum with scratch start tig on DCEN? My uncle welded aluminum with scratch start on AC by using a copper plate next to what he was going to weld. I have never tried it that way.
