B-4 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.
