The welder is rated 180 amperes, 25 volts, alternating
current at 50% duty cycle. Auxiliary alternating
current is available and output is 120 volts or 120/240
volts,
rated 5000 watts, 60 hertz at 100% duty cycle.
AC output is available at any time although at reduced
output when the welding current is being used. This
AC output is convenient for emergency lighting,
running power tools, etc., when working at locations
away from AC power line sources.
