Instructions / Assembly
Introduces your new 220 st Pro welder
New fault codes to help keep you and your welder, working efciently:
Highlights of your new welder:
• Dual-voltage 120V / 230V
• TIG welder
• Stick welder
• Pulse welding: allows welding
on thin materials
• Simple controls, saves time
setting up for each weld
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.
Allow welder to cool at least
10 minutes with machine ON
(observe and maintain proper
duty cycle). FAULT/THERMAL
OVERLOAD INDICATOR LED
should
Insufficient air flow causing machine
to overheat before reaching duty
cycle.
Check for obstructions blocking
air flow and ensure that there
are 12 inches of clearance
between any obstacles and
the vents on all sides of the
machine.
FAULT CODE F02
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
workpiece.
Make sure the TIG electrode
is not touching the grounded
workpiece.
Stick electrode stuck to workpiece Make sure that your stick
electrode is not stuck to the
grounded workpiece.
