- 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 Accidental contact can cause overheating and create a fire hazard. ■ Do not weld on drums, tanks, or any closed containers unless a qualified person has tested it and declared it or prepared it to be safe. ■ Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits.
