AC/DC STICK (CONSTANT CURRENT) WELDING
1.Remove the flange nuts from output terminals and place the work and electrode welding cables over the terminals. See Figure B.4. Replace and tight- en the flange nuts securely. Be sure the connec- tions are tight.
2.Select the appropriate electrode. See “Welding Tips 1" included with your RANGER 300.
3.Attach the work clamp securely to the work you are welding.
4.Insert the electrode into the electrode holder.
5.Set the IDLER CONTROL to AUTO and start the diesel engine.
6.Set the RANGE switch to a setting equal to or slightly lower than the welding current recommend- ed for the electrode being used. For the best weld- ing performance, always set the RANGE switch to the lowest
7.Set the POLARITY switch to the desired polarity
8.Set the OUTPUT control. For stick welding, always use a setting between 5 and 10 on the dial (blue range).
9.Strike an arc and begin welding. The OUTPUT control can be adjusted while welding.
CAUTION
DO NOT change the RANGE switch setting while welding. This can result in damage to the switch.

AFTER YOU FINISH WELDING:
1.Stop the engine.
2.Allow the electrode and work to cool completely.
3.Remove the work clamp from the work.
4.Remove any remaining piece of electrode from the electrode holder.
5.If you are finished using the RANGER 300 for welding, disconnect the welding cables from the weld output terminals. Reattach the flange nuts and leave them on the terminals.
