General Pipe Cleaners’ Hot-Shot 320 and Hot-Shot 400 pipe-thawing machines thaw pipes in minutes without tearing up floors, breaking through walls, or digging around pipes in frozen ground. The Hot-Shot 320 generates 320 amps of thawing power to thaw up to 100’ of 1-1/2” pipe, yet weighs just 30 lbs. The powerful Hot-Shot 400 generates 400 amps of thawing power to thaw frozen lines up to 175’ long and 1-1/2” in diameter. The Hot-Shot 400 also includes a dual-level output to switch to the 320 amp output. Both machines are compact, feature a heavy-gauge steel case, and carry a two-year warranty. General Pipe Cleaners
