SETUP

 

* This chart is only intended to show general guidelines for different wire sizes and for different

 

 

 

 

thicknesses of material. The settings should only be used at the beginning of a weld and must be

 

 

 

 

 

 

 

 

adjusted after stopping and carefully inspecting the weld. Proper welding takes experience.

 

 

 

Duty Cycle (Duration of Use)

BASIC WELDING

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 20% duty cycle at rated output (90A) must be allowed to rest for at

least 8 minutes after every 2 minutes 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.

WELDING TIPS

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 lights. 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.
