Duty Cycle (Duration of Use)

Avoid damage to the Welder by not welding for more than the prescribed duty cycle time. The Duty Cycle defines the number of minutes, within a 10 minute period, during which a given welder can produce a particular welding current without overheating. For example, this Welder with a 25% duty cycle on MAX setting must be allowed to rest for at least 7 minutes, 30 seconds after every 2 minutes, 30 seconds of continuous weld. Failure to carefully observe duty cycle limitations can easily over-stress a welder’s power generation system contributing to premature welder failure.

This welder has an internal thermal protection system to help prevent this sort of over-stress. When the unit overheats, it automatically shuts down and the Overload Indicator (22) lights, then the welder automatically returns to service after cooling

off. Rest the Gun on an electrically non- conductive, heat-proof surface, such as a concrete slab, well clear of the ground clamp while allowing the welder to cool with the Power Switch on, so that the internal Fan will help cool the welder. When the welder can be used again, use shorter welding periods and longer rest periods to prevent needless wear.
