Re: Electric Boat
- A possible problem with this is the duty cycle. The welder was
designed to put out 40 amps on an intermittent basis. Use of a motor
may well exceed the thermal designs of the electronics because power
draw from a motor is constant not intermittent.
You might want to have an engineer look at the internal components
for the intended purpose.

rated @40V DC 250A at 100% duty cycle per their spec sheet. These
welders can be used in fab shops etc. around the clock under constant

I agree with you that an electrical engineer needs to design the
