General Pipe Cleaners’ Hot-Shot 320 generates 320 amps of thawing power to thaw up to 100 feet of 1-1/2-inch pipe and weighs 30 pounds. With dual-level output and 400 amps of thawing power, the Hot-Shot 400 can thaw frozen lines up to 175 feet long and 1-1/2 inches in diameter. With a 15-amp breaker, users can switch the Hot-Shot 400 down to 320 amps and pull just 14 amps. To use, attach the pipe clamps and plug the machine into any convenient 115V receptacle. Both machines are compact, feature a heavy gauge steel case, and carry a two-year warranty.
