School me in circuits

I just pulled the trigger on a new Hobart Tigmate wich is the same machine as a Miller Econotig, and I need to get the electrical side figured out. I have 220 volt running to my garage allready for my table saw, it uses 2 110 volt circuits tied together, each of those circuits is a 30 amp, so does that mean I have 60 amps total at 220 volts?

No, you have 30 amps at 220 volts.

Correct. And since you still need the table saw, you can't derate those conductors to use for the welder. You'll need to run a new dedicated circuit for the welder.

OK thanks, I guess I'll have to call in a professional, 220volt still scares me.

Whats the draw of the hobart? I dont see why he cant use it if 30 amps is called for. Just as long as thats the only think pluged into the circuit.

That tigmate is the same as a Miller Econotig I think. At max (20% duty)amps the current is rated at 52 or 54 on the name plate on the rear of the machine.
