General Operating Instructions
Protective gear must be worn when using the Arc Welder;
1.The duty cycle defines the number of minutes, within a 10 minute period, during which a given Welder can safely produce a particular welding current. For example:
•At a 10% duty cycle (at 130 Amps AC), actual welding can occur for one minute and then the welder must cool for nine minutes.
•At a 15% duty cycle (at 100 Amps DC), welding can occur for 1.5 minutes and then the welder must cool for 8.5 minutes.
•Failure to carefully observe duty cy- cle limitations can stress a Welder’s power generation system, contribut- ing to premature Welder failure.
2.This Welder is equipped with an inter- nal thermal protection system to help prevent damage to the unit. When the Arc Welder overheats the Yellow Lamp (24) is illuminated on the con- trol panel and the unit automatically shuts down. Then the unit returns to service when it cools down and the Yellow Lamp turns off automatically.
(See Figure B.)
•Once the unit returns to service, follow a more conservative duty cycle routine to help prevent excess wear to the Welder.
3.Determine whether AC or DC welding is to be used.
4.Connect the Grounding Cable with Clamp (34) and Welding Cable with Electrode Holder (33) for either AC or DC operation. (See Figure B.)
