On a typical job using 1/8 in 7018 electrodes (125 amps, 20% duty cycle), expect over 20 hours of op- eration.

Welding at 150 amps at 40% duty cycle uses approximately 3/4 gal- lon per hour, or about 16 hours of operation.

A 2kW generator load at 50% duty cycle uses less than 1/2 gallon per hour providing over 24 hours of op- eration.
