ABSTRACT:
Disclosed herein is an instructional apparatus for underwater electric welding. The workpiece to be welded is clampable to a submergible bench mounted in a water tank on a power adjustable bench controllable by the trainee's feet while his hands are located in gloves mounted in the tank wall. Foot controlled valve and water pump auxiliaries enable the trainee to free his hands from the gloves quickly by dumping the water and to refill the tank after he has replaced his hands in the gloves. Pilot lights indicate the energized or non-energized condition of each auxiliary.
