Anleitung Zusammenfassung
Duty Cycle And Overheating Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating. . Exceeding duty cycle can damage unit and void warranty. Air-Cooled Models 100% Duty Cycle At 200 Amperes Using Argon 60% Duty Cycle At 250 Amperes Using Argon Continuous Welding 6 Minutes Welding 4 Minutes Resting Water-Cooled Models 100% Duty Cycle At 400 Amperes Using Argon Continuous Welding OM-1581 Page 9 OM-1581 Page 10 SECTION 3 – INSTALLATION Be sure that contact tip, liner, and drive rolls are correct for wire size and type. See Section 5 to change parts as needed. See Section 7 for list of other available contact tips. NOTE Review Section 3-1 through Section 3-4 to determine how equipment will be connected. Air-cooled models are shown in Section 3-1 through Section 3-4. For water-cooled models, supplied water hoses must be connected from wire feeder to coolant supply. Read entire Section 3 before installing equipment. 3-1.
