Installation Guide
Introduces your new 220 Ac/dc welder
New fault codes to help keep you and your welder, working efciently:
Highlights of your new welder:
• Dual-voltage 120V / 230V
• TIG welder (AC/DC)
• Stick welder
• Low frequency TIG to weld on
automobiles with computers
• AC/DC allows you to weld
on all materials including
aluminum
What does dual-voltage mean
for you?
Your Forney welder is equipped
with dual-voltage capabilities
meaning it can be plugged into
either 110-120V or 208-240V
single phase. This machine can
only perform at full capabilities
with good input power. The higher
the input means higher the output.
This means a dedicated circuit,
proper breaker, proper wire gauge
size and no extension cord will
produce maximum output.
When used with a 120V power
source the output will be reduced
making it ideal for DIY or light
contractor projects. For a 120V
it’s good for most ¼” applications
on down.
When used with 240V outlet,
your machine will achieve its full
performance and output for more
demanding applications. For 240V
it’s good for most ½” applications
on down.
FAULT CODE F01
DISPLAYED.
Exceeded duty cycle; thermal
protector engaged.
Verify that circuit breaker has not
been tripped in your main power
panel. Reset if needed.
POWER SWITCH is OFF. Ensure POWER SWITCH (rear) is in
the ON position.
FAULT CODE F02
DISPLAYED.
No voltage or incorrect voltage
supplied to welder.
Make sure the machine is plugged
in. Check the status of your INPUT
VOLTAGE INDICATOR LED. It
should be illuminated. Check the
voltage of your outlet. If it is 10%
more or less than 120V or 230V,
call a qualified electrician.
FAULT CODE F05
DISPLAYED.
Torch triggered before
machine is ready
Torch triggered or turned on
before machine is powered on
will fault. Release torch trigger
and machine will reset within
five seconds
FAULT CODE F09
DISPLAYED.
Output short or abnormal
voltage feedback.
Make sure the MIG wire is not
touching the grounded work
piece.
Make sure the TIG electrode is
not touching the grounded work
piece.
Stick electrode stuck to
workpiece
Make sure that your stick
electrode is not stuck to the
grounded workpiece.
