Resumen del manual
6 Minutes Welding 4 Minutes Resting 2-2. Duty Cycle And Overheating Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating. If unit overheats, output stops, a Help message is displayed (see Section 5-2), and cooling fan runs. Wait fifteen minutes for unit to cool. Reduce amperage or voltage, or duty cycle before welding. Exceeding duty cycle can damage unit and void warranty. 60% Duty Cycle Overheating 0 15 A or V OR Minutes Reduce Duty Cycle sduty1 5/95 / SA-207 877 2-3.

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 shielded cables, using line filters, or shielding the work area.
