5-2. Description Of Controls (See Section 5-1)

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 if starting a cold engine. Move control to left if starting a warm engine.

3Starter Handle To Start:

DOpen fuel valve (see Section 4-4).

DTurn engine switch to On.

DSet choke.

DPull starter handle until engine starts.

Open choke as engine warms.

.This unit has a low oil level shutdown to prevent starting an engine that is too low on oil. The low oil level shutdown may not stop a running engine. Check oil level if the engine does not start, or has stopped and cannot be restarted.

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 Current 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 Current Control: Use electrode chart (see Section 5-3) to determine correct size electrode. Select electrode type and set cur- rent control to corresponding amperage range on nameplate. Adjust control within se- lected range to obtain desired weld performance.

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

Current Control Setting: 80 – 125 A

5-3. Amperage Selection Table For Stick (SMAW) Electrodes

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

Values listed are suggested settings. Actual settings may vary depending on personal preference and/or specific application. Suggested electrode for beginners is E7018 AC.
