cycle (at 70 Amps), actual welding can occur for one minute and then the welder must cool for nine minutes. At a 20% duty cycle (at 50 Amps), welding can occur for 2 minutes and then the welder must cool for 8 minutes.
•Failure to carefully observe duty cycle limitations can stress a Welder’s power generation system, contributing to premature Welder failure.
•This Welder is equipped with an internal thermal protection system to help prevent damage to the unit. When the Arc Welder overheats a red light is illuminated on the control panel and the unit automatically shuts down. Then the unit returns to service when it cools down and the red light turns off.
•Once the unit returns to service, follow a more conservative duty cycle routine to help prevent excess wear to the Welder.
2.Attach the Ground Cable with Clamp (10) as close as possible to the intended welding location.
(See Assy. Diagram.)
3.Place the bare end of the electrode (not included) in the Electrode Holder
(9). NOTE: Always keep the jaws of the Electrode Holder clean to ensure proper electrical contact with the electrode. (See Assy. Diagram.)
4.Set the desired current (50~70 Amps) for the type of metal being welded with the MIN/MAX Switch (12). Thin metals use low current and heavy metals use high current.
(See Assy. Diagram.)
5.Make sure the Power Switch (13) is off, then plug the Arc Welder’s Power Cord (8) into a dedicated, 120 VAC, 20 amp line with delayed action type circuit breaker or fuses.
(See Assy. Diagram.)
6.While grasping the handle of the Electrode Holder (9), with the electrode clear of grounded objects, turn the Power Switch (13) to its “ON” position. (See Assy.
Diagram.)
7.Hold the Welding Shield in front of your eyes. WARNING! Never look at the ignited arc without ANSI- approved, arc shaded, eye protection in a full face shield. Permanent eye damage or blindness can occur. Skin burns can occur. Wear a
8.Stroke the area to be welded with the electrode to ignite the arc. Never tap the electrode into the welding surface to ignite the arc. This damages its external coating on the electrode which prevents oxygen in the air from coming into contact with the molten metal, causing it to oxidize.
9.Once the arc is ignited, tilt the electrode backward at an angle of approximately 30° and hold it at a distance from the welding object equal to the diameter of the electrode.
10.NOTE: If too much current is drawn from the Arc Welder, the Thermal Overload Protector will activate. The red light on the Control Panel will illuminate, and the Welder will automatically shut off until it cools down. If this happens, turn the Power
