Chicago Electric 68887 manual Up to 2 minutes welding At rated output, Hold GUN Clear

Page 17

Note: If Welder is used too long, the amber Overload Indicator will light and the Welder Gun will shut off until the welder cools. If this happens, rest the Gun on an electrically non-conductive, heat-resistant surface, such as a concrete slab, well clear of the ground clamp. Wait about 8-10 minutes with the Power Switch to ON for the welder to cool. When the welder can be used again, use shorter welding periods and longer rest periods to help prevent needless wear.
