Miller Sinc-wave is prolly one of the premier machines out there. The good machines have inverters, and you need a lanthinated tungsten to use that type of welder. If he's blowing holes he needs to turn down the high freq, weld electrode ac minus. Also the copper chill plates will help also.

muffler welding
So ok ,here is my 2c's worth and don't laugh to much. I bought something called kel-arc a few years back that i use to stitch thin metal together, i am a poor excuse for a welder but that works for me . I don't remember where i got it but maybe northern tool, not sure. Ray
I was at the track, hitting over the sound limits an noticed that I had 2 large 1-2" diameter holes in my muffler from a bad install technique that used hangers that welded to the sides, and that skin couldnt handle the weight of the muffler and tore off. i fixed that and relieved the stress with another style of hanging system, but how can i fix the holes? i used rivets and plates of aluminum, and that worked for the race, but they came a little lose and vibrate and buzz like its a blown muffler. its amazing on a free flow muffler, still how much pressure is in the can. 
you can feel exhaust escaping, like a header leak.
anyway, im thinking JBweld and then the rivets or is there a better way?

Welding machines are a lot like cameras, I have friends that take far better pictures with a disposable than I can with my Nikon.
Many can weld better with a cheap machine than I can with a good one.
