POWER WAVE® C300 CE
COLD FEED/GAS PURGE SWITCH
Cold Feed and Gas Purge are com-
bined into a single spring centered tog-
gle switch.
To activate Cold Feeding, hold the
switch in the UP position. The wire
drive will feed electrode but neither the power source
nor the gas solenoid will be energized. Adjust the
speed of cold feeding by rotating the WFS knob.
Cold feeding, or "cold inching" the electrode is useful
for threading the electrode through the gun.
Hold with toggle switch in the DOWN position to acti-
vate Gas Purge and let the shielding gas flow. The
gas solenoid valve will energize but neither the power
source output nor the drive motor will be turned on.
The Gas Purge switch is useful for setting the proper
flow rate of shielding gas. Flow meters should always
be adjusted while the shielding gas is flowing.
PUSH / PULL OPERATION
• Set the idle roll pressure on the wire drive between
an indicator reading of 0-2. A recommended start
point is 1.5.
• Configure the machine for push/pull operation (see
parameter P.17 in the Set-up Menu section).
• Depending on the weld mode, set the Voltage or
Trim at the Power Wave® C300 CE using the right
control knob located on the upper case front panel.
• The Wire Feed Speed (WFS) is set using the control
knob on the Torch. The left control knob on the
Power Wave® C300 CE is inactive. The actual WFS
being set at the torch is displayed on the Power
Wave® C300 CE.
• All weld parameters normally available for the active
weld mode are available during push-pull operation.
