ARC RAYS can burn eyes and skin. BUILDUP OF GAS can injure or kill. Shut off shielding gas supply when not in use. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays Always ventilate confined spaces or use that can burn eyes and skin. Sparks fly off from the approved air-supplied respirator. weld. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 li

3-4. Duty Cycle And Overheating Duty Cycle is the percentage of 10 minutes that the unit can weld at rated load without overheating. If unit overheats, output stops, front panel voltmeter/ammeter displays a HLP3 or HLP5 message (see Section 5-4), and cooling fans run. Wait fifteen minutes for unit to cool. Reduce amperage or duty cycle be- fore welding. Exceeding duty cycle can damage unit and void war- ranty. 40% Duty Cycle At 350 Amperes (60 Hz Models Only) 60% Duty Cycle At 300 Amperes 6 Mi

3-6. Weld Output Terminals And Selecting Cable Sizes ARC WELDING can cause Electromagnetic Interference. To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor. Locate welding operation 100 meters from any sensitive electronic equipment. Be sure this welding machine is installed and grounded according to this manual. If interference still occurs, the user must take extra measures such as moving the welding machine, using shiel
