Page 6: Personal Protection
Personal Protection Welding processes of any kind can be dangerous not only to the operator but to any person situated near the equipment, if safety and operating rules are not strictly observed. THE WELDING ARC PRODUCES VERY BRIGHT ULTRAVIOLET AND INFRARED LIGHT. THESE ARC RAYS WILL DAMAGE YOUR EYES AND BURN YOUR SKIN IF YOU ARE NOT PROPERLY PROTECTED. -
Page 7: Fire Prevention
• Do not weld in a confined area unless it is being ventilated or the operator (and anyone else in the area) is wearing an air-supplied respirator. • Stop welding if you develop momentary eye, nose, or throat irritation as this indi cates inadequate ventilation. -
Page 8: Arc Welding
Arc Welding • Computers and computer driven equipment can be harmed with electromagnetic energy. • Be sure all equipment is compatible with electromagnetic energy. • Keep welding cables short to reduce interference. • Follow manual to install and ground machine. •... -

Page 15: Thermal Overload Protection
Thermal Overload Protection CAUTION If the duty cycle of the welder is exceeded, a thermostat will automatically cut the power to prevent the machine from overheating. If this should happen do not unplug the machine but let it cool down. Then the thermostat will automatically reset itself and you can continue welding. -
Page 16: Welding Pitfalls
Welding Pitfalls 1. Arc distance too short - this causes irregular masses of weld to be deposited with slag contamination on the uneven surface. 2. Arc distance too long - this causes poor penetration resulting in a weak weld with excessive spatter and porosity. -
