Additional Features

Exceptional electrical efficiency. At 400 A, efficiency is 87.24%!

350 A of welding output at 60% duty cycle with superior low-end performance.

Power factor of .95 enables smaller fuses/breakers and primary wiring. Primary amperage draw at rated output is 25% less than the competition.

Ultra-tough, polycarbonate-blended cover for control panel protects front controls from damage.

Optional gas solenoid for TIG welding.
