EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc or
begin welding until you are adequately protected. Wear flame-proof welding gloves, a heavy long
sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved welding helmet.
OPERATION
High voltage danger from power source! Consult a qualified electrician for proper
installation of receptacle at the power source. This welder must be grounded while in use to
protect the operator from electrical shock. If you are not sure if your outlet is properly grounded,
have it checked by a qualified electrician. Do not cut off the grounding prong or alter the plug in
any way and do not use any adapter between the welder's power cord and the power source
receptacle. Make sure the POWER switch is OFF then connect your welder's power cord to a
properly grounded 380 VAC, 60 HZ, 3 phase, 50 amp power source.

brittle and porous welds. If the base metal pieces to be joined are thick or heavy, it may be necessary to
bevel the edges with a metal grinder, the correct bevel should be around 60 degree. See following
