below 90VAC under load
Input voltage is higher than 500VAC or
spikes above 500VAC during load
Input voltage not configured correctly
Indicates that an internal auxiliary voltage
fault condition is detected.
condition is detected.
A communication error between the
control and UI board has occurred.

Course Of Action
Check the input voltage with and without a load applied,
check the cable size, and fuse size.
Check the input voltage with and without a load applied.
Turn OFF the machine and check the input connections. If
three phase is being applied, ensure the voltage is at
least 185VAC
Indicates that an overload condition occurred. Turn off the
machine, wait one minute and then turn the machine on.
Turn off the machine, wait one minute and then turn the
machine on.
Turn off the machine, wait one minute and then turn the
machine on.
Turn off the machine, wait one minute and then turn the
machine on.
Check the TIG torch for kinks, check the cooler
connections, verify the fluid in the cooler is within the
suggested limits, replace damaged torch, replace torch
with a higher ampacity torch, toggle flow switch on cooler
to remove the error code.
Water cooler was connected/disconnected during
operation. Turn off the machine, connect the cooler, wait
