OPERATION
B-4
PIPELINER 200D
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 240-160
position and the “Fine Current Adjustment” setting to
get 175 amps.
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 posi-
tions 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 100-150 watts minimum) from the
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 re-started before
the end of the time delay, the idler solenoid deacti-
vates and reduces the engine to low idle speed.
AUXILIARY POWER
1.80 kW of 120V DC auxiliary power at 35% duty
cycle maximum is available at the receptacle located
on the control panel.
