Hi

My initial post might have read that the alternator was only 60 amps.

In fact each of the diodes is rated at 60 amps. I have a large piece of aluminum for a heat sink.

I had planned to use at least 4 of these diodes.

I will post some pics of the transformer if you want.

By using the Variac I would also have a variable voltage DC battery charger.

I want to add a cheap Multimeter to the circuit so I can get consistant bow temperatures for the different size bows and battery charging.

I don't know whether I should put it on the AC output from the variac or on the DC output from the transformer?

Thanks guys

Here are the specs for the welder.

Primary volts 115
Primary amps 15
Amps output 50
Open circuit volts 45
Arc volts 25
Duty cycle 20%
