CONTROLS AND SETTINGS
All operator controls are located on the Front
Panel/Nameplate of the machine. See Figure B.1 for
the location of each control.
Figure B.1 - Operator Controls.
1. POWER SWITCH: Toggle switch to turn input
power ON and OFF. Place the lever in the ON
position to turn the WIRE-MATIC 255 ON.
2. PILOT LIGHT: The red LED pilot light located next
to the POWER SWITCH is lit when the power is
ON.
3. VOLTAGE CONTROL POTENTIOMETER KNOB:
Provide continuous adjustment of power source
output voltage over the rated 12 to 28 volt range.
Voltage can be adjusted while welding.
4. WIRE SPEED CONTROL POTENTIOMETER
KNOB: Controls the wire speed from 50 to 600
inches per minute (1.2 to 15.2 m/min). The control
can be preset on the dial to the setting specified on
the Procedure Decal on the inside of the wire com-
partment door. Wire speed is not affected when
changes are made in the voltage control.
NOTE: When the trigger is pulled, the wire feeder
feeds wire at low speed regardless of the wire feed
speed set on the control until the welding arc starts or
2 seconds has elapsed. This feature enhances start-
ing and makes it easier to set the stickout. The 2 sec-
ond limit permits high speed loading of the gun and
cable.
