RECOMMENDED
COURSE OF ACTION
Machine is Dead -No Output
- No Fan
1. Make certain that the input power
switch is in the "ON" position and
machine is plugged in.
2. Check the input voltage at the
machine. Input voltage must match the
rating plate and voltage connection.
Refer to Reconnect Procedure in the
Installation section of this manual.
3. Blown or missing fuses in input line.
Fan runs normally at power
up - No output from machine
in either Stick or TIG modes.
1. Check for proper input voltages per
nameplate and voltage reconnection.
2. Check to make sure polarity switch is
not in between two positions.
Fan runs - No output from
machine in either Stick or
TIG modes and the yellow
light on the control panel is
on.
1. Welding application may have exceed
the recommended duty cycle. Allow the
unit to run until the fan cools the unit and
the yellow light goes out.
Machine does not respond
(no gas flow, no high
frequency and no open
circuit voltage) when arc start
switch or Ampcontrol is
activated - fan is working.
1. Machine MUST be in the TIG Mode.
2. The Ampcontrol may be defective.
Check for continuity between pins
"D" and "E" on cable connector when
Ampcontrol is depressed.
Welding stops, and warning
light is on
Self-protection has engaged
1.Display "E01" -over-temperature
2.Display "E02" -over-current,
3.Display "E05"- torch switch always close
4.Display "E06"- air pressure is too
lower @CUT
I
f all recommended
possible areas of
misadjustment have
been checked and the
problem persists,
Contact your local
Authorized Field Service
Facility.
Note:Both the Hand and
Adjustable foot control
work in a similar manner. For simplicity, the following
explanation will refer only to "Ampcontrol", meaning both Foot and Hand models
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely,
contact your Local Authorized Field Service Facility for technical troubleshooting assistance before you
proceed.
