5-3. Description Of Controls (Honda-Powered Units) (See Section 5-2)

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

1 Engine Switch

On models with recoil-start, use switch to open ignition circuit, and to stop engine.

On models with electric-start, use switch to open ignition circuit, and to start and stop en- gine.

2 Throttle Control Lever

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

.Always place lever in Run position (far left) for auxiliary power and for maximum weld output.

3 Choke Control Lever

Use lever to change engine air/fuel mix. Move

lever to left if starting a cold engine. Move le- ver to right if starting a warm engine.

4Starter Handle (Recoil-Start Models Only)

To Start (Recoil): open fuel valve, turn engine switch to On, move throttle lever to Idle, set choke, and pull starter handle. Open choke as engine warms.

To Start (Electric): open fuel valve, move throttle lever to Idle, set choke, and turn en- gine switch to Start position. Open choke as engine warms.

YIf the engine does not start, let engine come to a complete stop before at- tempting restart.

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 on nameplate. Adjust control within selected range 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
