SECTION 1 DESCRIPTION
ELECTRIC SHOCK CAN KILL! Make
sure that all primary input power to the
power source and wire feeder has been
disconnected at the wall (line) discon-
nect switch or circuit breaker before
making the following connections.
A. PULSE CONTROL PANEL DESCRIPTION
(Refer to Figure 2-1)
1. FAULT LAMP
The RED fault light on the MultiPower 460 Pulse front panel indicates a
problem with set-up parameters. A "Steady" light "On" indicates there is no
program for the material and wire diameter selected. A "Blinking" light
indicates the wire feed speed is out of the recommended range..
2. TEMPERATURE LAMP
The TEMP lamp illuminates if an over temperature condition occurs within the
MultiPower 460 Pulse power source. This condition may be caused by
excessive duty cycle or over-current conditions. When an over temperature
condition occurs, the welding output is turned off and the unit must be allowed
to cool. The machine will automatically reset when the temperature falls to a
safe level.
3. PROCESS SELECTOR SWITCH
The three position process selector switch is located in the upper right-hand
corner of the control panel. The process selector switch position provides the
visual indication of which weld process (Mig, Tig or stick) has been selected.
4. DIGITAL DISPLAYS (WFS, AMPS & VOLTS)
The digital displays located on the left side of the control panel are multifunc-
tional depending on the welding process being used. The top display reads
wire feed speed in inches per minute in the MIG PRESET mode and welding
current (in amps) in the TIG and STICK PRESET mode. During welding both
displays indicate average welding current (amps) and average welding
voltage.
The wire feed speed is displayed in inches per minute (IPM) in the top display
when the PRESET button is pressed and the wire speed adjustment knob on
the wire feeder is turned. The WFS LED beside the top display will light when
the display is showing wire feed speed.
5. VOLTAGE/CURRENT/TRIM ADJUST KNOB
The arc voltage is controlled with this knob when the WELD PROCESS
selector switch is in the MIG position. The Mig arc voltage can be preset by
pressing the PRESET button and reading the arc volts in the bottom digital
display while turning this knob.
The arc current is controlled with this knob when the WELD PROCESS
SWITCH is in the TIG or STICK position. The welding current can be preset
in amperes by pressing the PRESET button and reading the current (amps)
in the top digital display while turning this knob. The average arc current will
be displayed during welding.
For MIG PULSE welding, the arc length (arc voltage) is controlled with this
knob. The WELD PROCESS switch is placed in the MIG position and the MIG
PROCESS switch is placed in the MIG PULSE position. The knob should be
place at the 12 o'clock position as the synergic preset for the wire feed speed,
WIRE TYPE and WIRE DIAMETER chosen by the operator using the PULSE
SELECTION switches. The arc length can then be adjusted by turning the
knob clockwise to increase the arc length or counterclockwise to decrease the
arc.
