K1542-6 “M” PANEL
The M Panel provides a fixed large bat toggle switch
selection of three Power Source modes. The upper
position selects the generic CV/MIG mode from the
power source, the middle position selects the
CV/FLUX CORED mode, and the lower position
selects the CC/STICK/GOUGE mode. Arc control is
accomplished through the use of the ARC CONTROL
potentiometer. The arc control value is actually a trim
with zero being the nominal and the scale ranging
from (-10) to (+10). Preflow, postflow, and spot time
default to zero or off. Run-in defaults to the minimum
value, or weld speed depending on the position of its
associated dip switch. Burn back defaults to the on
board trimmer adjustment.
NOTE: Due to the nature of fixed position switches,
potentiometers, and default values, this option
does not allow the mode, arc control, timers,
or Burn back values to be included in dual pro-
cedure or memory information. They are over-
ridden by the fixed values.
CC/STICK/GOUGE Mode
Selecting the CC/STICK/GOUGE mode on this panel
automatically energizes the output terminals on the
power source, making the power source immediately
ready to weld. In the CC modes, the output current is
set by the Amps control, and the Volts/Trim adjust-
ment has no effect in this mode. In this mode, the Arc
Control adjusts the arc force. Increasing the Arc
Control setting increases the arc force, making the arc
more harsh but less likely to stick. Decreasing the Arc
Control setting decreases the arc force, making the
arc softer and smoother.
Constant Voltage (CV/Weld, CV/MIG, CV/Flux
Cored) Procedures
When in this mode, the Arc Control adjusts the induc-
tance. (This adjustment is often referred to as ʼpinch”.
Inductance is inversely proportional to pinch.)
Increasing the Arc Control setting decreases the
inductance, which results in the arc getting colder and
pinched tighter. Decreasing the Arc Control setting
increases the inductance, which results in the arc get-
ting wider (reduced pinch).
Installation is as follows:
1. Turn off power.
2. Remove the two screws from the front of the stan-
dard or option panel at the location you choose to
install your new option, (bottom), of the Control
Box cabinet. Save the screws for re-use. Unplug
the white electrical connector. Remove the chas-
sis wire (if equipped) from the back of the stan-
dard or option panel. Discard the old panel or
save for future use.
3. Tilt the new option panel away from the front
opening of the Control Box cabinet and plug the
white electrical connector into the proper connec-
tor (12 pin) on the right side of the main printed
circuit board until the connector latches into
place. Attach the chassis wire (if equipped) to the
back of the new panel.
4. Slide the new panel through the opening, taking
care not to damage the connections and the print-
ed circuit board on the back.
5. Align the screw holes, replace the two screws and
tighten.
