- Page 2 ■ TECHNICAL SPECIFICATIONS - SUFFICIENT CAPACITY of main transformer by self-manufacturing - ELECTRIC SHOCK PROTECTOR reduces No load voltage to 14VDC for user safety when welder is not in use. - Easy to verify welding current during welding by DIGITAL AMMETER. - Optional REMOTE CONTROL BOX is available for adjusting output current without going back to power source.
- Page 3 General Safe Practices ■ Wear approved safety glasses with side shields under your welding helmet or face shield and at all times in the work area. ■ When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.
- Page 4 1. Welding sparks can cause fire or explosion. ■ Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and opening to adjacent areas.
