.Weld and generator power output stops if generator overheats or engine speed is too low.

1 Engine Switch

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

2 Throttle Control Lever

Use lever to select engine speed. Move lever to idle position (far left) for idle speed. Move le- ver to Run position (far right) for weld/power speed.

.Always place lever in Run position (far right) for generator power and for maxi- mum weld output.

3 Choke Control Lever

Use lever to change engine air/fuel mix. Move lever to right if starting a cold engine. Move le- ver to left if starting a warm engine.

4 Starter Handle

To Start: open fuel valve (see Section 5-4), turn engine switch to On, move throttle lever to Idle, set choke, and pull starter handle.

Open choke as engine warms.

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.

5 Welding Range Label

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

6 Current Control

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

To Set Current Control: Use label to deter- mine correct size electrode for material thick- ness. Select electrode type and set current control to corresponding amperage range. Adjust control to obtain desired weld performance.

EXAMPLE:

Material Thickness: 1/8 to 1/4 in

Electrode Diameter: 1/8

Electrode Type: E-6013

Current Control Setting: 90 − 120 A
