CAUSE/SOLUTION
Machine will not turn on. No

indicator light.
Check cords and wiring in the plug. Check circuit
breaker.
Machine runs, but will not weld in either mode.
Check for sound work clamp and cable connections.
Make sure work cable and TIG Torch are securely fas-
tened to their terminal connectors. Reset main power
switch if overcurrent light is on. Contact Technical
Support.
Arc will not start unless lift started.
Check for good work clamp and all connections.
Ground directly to the work. Check point gap. If all
connections are secure, contact Everlast.
Tungsten is rapidly consumed.
Inadequate gas flow. Tungsten is too small of a diam-
eter for amps used. Wrong shielding gas. Use only Ar.
Using green tungsten. Use red thoriated or other col-
or. Wrong polarity. Too much AC cleaning.
Tungsten is contaminated, arc changes to a green color.
Weld is discolored or a dusty brown.
Tungsten is dipping into weld. Check and adjust stick
out to minimum 1/8 inch. Tungsten is melting. Re-
duce amperage or increase tungsten size.
Porosity of the Weld. Discolored weld color. Tungsten
is discolored.
Low flow rate of shielding gas. High flow rate of
shielding gas. Too short of post flow period. Wrong
TIG cup size.
Possible gas leaks internally or externally due to loose
fittings. Base metal is contaminated with dirt or
grease.
Weld quality is poor. Weld is dirty/oxidized.
Eliminate drafts. Check if there is sufficient shielding
gas left in tank. Check gas flow. Adjust for higher flow
of gas. Listen for audible click of gas solenoid. If no
click is heard, then contact Everlast Support. Clean
weld properly, especially in Aluminum. Too short of
post flow. Check tungsten stick out.
Over current/Duty cycle LED illuminates. Machine runs,
but no output.
Duty cycle exceeded or Over current. Allow machine
to cool. Reset main power switch after full cool down
period. Make sure fan is not blocked. Check wiring.
Unstable Arc.
Poorly ground or shaped tungsten. Regrind to proper
point. Too much AC positive polarity. Reduce balance
to 30% or less. Increase AC Frequency. Bad work
clamp or work clamp cable connection. Wrong polari-
ty. Use a negative torch connection for TIG and plas-
ma. Use Positive for Stick.
Other issues.
Contact Everlast support.
