How much fuel does the Bobcat 250 consume during typical welding operations?

On a typical job using 1/8 in 7018 electrodes at 125 amps and 20% duty cycle, you can expect about 20 hours of operation from a full tank. Welding at 150 amps at 40% duty cycle uses approximately 3/4 gallon per hour, providing about 16 hours of operation. (Page 14)
