Delivering clamp-plug-thaw functionality, Hot-Shot Models 320/400 unfreeze pipes in minutes to eliminate tearing up floors, breaking through walls, or digging around pipes in frozen ground. Hot-Shot 320 generates 320 A to thaw up to 100 ft of 1-1/2 in. pipe. Including dual-level output, Hot-Shot 400 generates 400 A to clear frozen lines up to 175 ft long with 1-1/2 in. dia lines. If users are on job with only 15 A breaker, they can switch Hot-Shot down to 320 A and pull just 14 A.
