| OPERATION | ||
When a forceful “digging” arc is required, usually for |
| |||
vertical and overhead welding, use a higher “Current |
| |||
Range Selector” setting and lower open circuit voltage. |
| |||
For example: to obtain 175 amps and a forceful arc, set |
| |||
the “Current Range Selector” to the |
| |||
and the “Fine Current Adjustment” setting to get 175 |
| |||
amps. | CAUTION |
|
| |
|
|
|
| |
DO | NOT attempt to set the “Current Range Selector” |
| ||
between the five points designated on the nameplate. |
| |||
| ||||
These switches have a spring loaded cam which |
| |||
almost eliminates the possibility of setting this switch |
| |||
between the designated points. |
|

IDLER OPERATION |
|
| ||
Start the engine with the “Idler” switch in the “High” position. Allow it to run at high idle speed for several minutes to warm the engine. See Specifications for operating speeds.
The idler is controlled by the “Idler” toggle switch on the welder control panel. The switch has two positions as follows:
1. | In the “High” | position, the idler solenoid acti- | |
vates, and the engine goes to high idle speed. The | |||
speed is controlled by the governor. | |||
2. | In the “Auto” | / | position, the idler oper- |
ates as follows: |
|
| |
• | When welding or drawing power for lights or tools | ||
| (approximately | ||
| receptacle, the idler solenoid activates and the engine | ||
| operates at high idle speed. |
| |
• When welding ceases or the power load is turned off, a preset time delay of about 15 seconds starts. This time delay cannot be adjusted.
• If the welding or power load is not
AUXILIARY POWER
1.80kW of 120V DC auxiliary power at 35% duty cycle maximum is available at the receptacle located on the control panel.
