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.
