1 Engine Switch

Use switch to control ignition circuit, and to stop engine.

2 Choke Control

Use control to change engine air/fuel mix. Move control to right (Choke) if starting a cold engine. Move control to left (Run) if starting a warm engine.

3Starter Handle To Start:

D Open fuel valve (see Section 5-5). D Turn Engine switch to On.

To Stop: turn engine switch to Off.

.Always close fuel valve after stopping

unit. Moving unit with fuel valve open may cause carburetor flooding and make starting difficult.

4 Amperage Control

Use control to select weld amperage. Control may be adjusted while welding. Set Amper- age control at max. for full generator power output at ac receptacles.

To Set Amperage control: Use electrode chart (see Section 6-3) to determine correct size electrode. Select electrode type and set Amperage control to corresponding amper- age range on nameplate. Adjust control within selected range to obtain desired weld performance.

EXAMPLE: Electrode Type: 6013 Electrode Diameter: 1/8

Amperage control Setting: 80 − 125 A

6-3. Amperage Selection Table For Stick (SMAW) Electrodes

Use table to select correct amper- age for the electrode being used.

. For best results, use Stick electrodes designated for AC welding.

226 005-A

Values listed are suggested settings. Actual settings may vary depending on personal preference and/or specific application. Suggested electrode for beginners is E6013.
