6-4. Description Of Controls (DX Models) (See Section 6-3)

1 Engine Switch

Use switch to control ignition circuit. Turn switch to Start position for electric start. Turn switch to On position to start engine using starter handle (recoil). Turn switch to Off posi- tion to stop engine.

2 Low Oil Level Light

Light goes on and engine stops if engine oil level is too low.

Engine cannot be restarted until sufficient oil is added.

Stop engine and add oil if light goes on (see Section 5-4).

3 Starter Handle

Use starter handle to start unit if electric start does not work.

4 Choke Control

Use control to change engine air/fuel mix. Move control to far right if starting a cold en- gine. Move control to far left if starting a warm engine.

The engine starts at weld/power speed and runs at weld/power speed under weld or gen- erator power load. The engine returns to idle speed 12 seconds after start-up or after weld or generator power load is removed.

To Start:

DOpen fuel valve (see Section 5-4).

DSet choke.

DElectric-Start: Turn Engine switch to Start position.

Recoil: Turn Engine switch to On posi- tion. Pull starter handle until engine starts.

DOpen choke as engine warms.

If the engine does not start, let engine come to a complete stop before attempting restart.

To Stop:

DTurn 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.

5 Welding Range Table

Use table to determine correct weld amper- age based on electrode size, type, and mate- rial thickness.

6 Run / Idle Switch

Use switch to select whether the engine stays at run speed continuously or whether the auto idle feature is enabled so engine speed re- turns to idle speed after start−up or after weld or generator load is removed.

7 Weld Output Control

.Set control at maximum for full generator power output at AC receptacles.

Use control to select weld amperage. Control may be adjusted while welding.

To Set Weld Output Control: Use table to determine correct size electrode for weld am- perage. Select electrode type and set control to corresponding amperage range on name- plate. Adjust control to obtain desired weld performance.

EXAMPLE:

Electrode Diameter: 1/8

Electrode Type: E-6013

Current Control Setting: 90 − 120 A 8 Hourmeter

Use hourmeter to help schedule routine main- tenance.

Notes

Work like a Pro!

Pros weld and cut safely. Read the safety rules at the beginning of this manual.
