Control of Welding Current
CAUTION
DO NOT TURN THE “CURRENT RANGE SELEC- TOR” WHILE WELDING because the current may arc between the contacts and damage the switch.
The “Current Range Selector” provides five overlap- ping current ranges. The “Fine Current Adjustment” adjusts the current from minimum to maximum within each range. Open circuit voltage is also controlled by the “Fine Current Adjustment” permitting control of the arc characteristics.
A high open circuit voltage setting provides the soft “buttering” arc with the best resistance to
When a forceful “digging” arc is required, usually for vertical and overhead welding, use a higher “Current Range Selector” setting and lower open circuit volt- age. For example: to obtain 175 amps and a forceful arc, set the “Current Range Selector” to the
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.

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 is off, and the engine runs at the high speed controlled by the governor.
2. In the “Automatic” | / | position, the |

Carburetor Deicing Kit
A carburetor deicing kit is installed on Classic welders leaving the factory. The purpose of the Carburetor Deicing Kit is to prevent carburetor icing when the outside temperature is 60°F/15.5°c or lower. See Carburetor Deicing Kit Usage Instructions For Seasonal Change Over on page B3.
