I bolted a piece of aluminum angle to the brass bar on my magnetic burning square. Works great on steel, but the magnets don't hold very well to aluminum or stainless steel, maybe they're wore out?:confused2:

Good stailess is usually non magnetic. You need special magnet for Al. It is similar to oak magnet used for welding of oak boars with hard wood electrodes.

Don't forget to hook up the ground, pilot arc can trick you into thinking you're good to go.

:laughing: The other day I kept wondering what was wrong with my plasma cutter..was only getting 16 amps of cutting current instead of the full 40..finally noticed I had the ground from the MIG connected to what I was trying to cut instead of the PC ground, its tough getting old:rolleyes:

As said the dry air is very important, I kept having the arc extinguish on my PC until I added an inline desiccant dryer.

t is similar to oak magnet used for welding of oak boars with hard wood electrodes.

I find that the best electrode holder for that weighs about 16oz, and has a claw.
