Troubleshooting
If your unit is not properly functioning, please call us immediately toll free at 1-877-566-4462 for support. We
have included a small table here to diagnose most common problems.
Problems, Causes, and Solutions
Problems
Causes/
Solutions
Machine will not
turn on.
Check cords and breaker. If nothing is found, contact
LONGEVITY
The machine runs,
but nothing is
happening
Check to see if you are in the right mode, plasma cutter, tig,
stick. Check the torches and your ground. Make sure there is argon
or compressed air for plasma and tig.
Pilot Arc will not
start
Check the ground connection. Check the torch for proper
consumables installation. Replace consumables.
Consumables
(tips) are being
consumed
Improper air/gas flow. Increase the PSI on the regulator, check
for leaks in the hose, maintain a distance of 1/8” from the torch tip
or workpiece
Heavy Underside
Slag (Cutting)
Slow travel speed. Increase travel speed or amperage on unit.
Poor Cut Quality
Check Air Pressure. Insure your unit is capable of cutting the
desired thickness of material. Check the consumables to insure they
are producing a stable arc. Replace Consumables and insure you
have the proper PSI at the regulator.
Inconsistent
Arc
Improper grounding or possible lack of air pressure. Check and
replace consumables and adjust the regulator to proper PSI
O.C. Over
Current LED
Lights
The unit has reached its DUTY Cycle. Leave power of the
machine on and allow fans to cool the machine. You can also turn
the machine off to properly cool it. Do not continue to weld until
light is off.

Unit Will Not
Weld
Check ground connection, torch setup, and check if you are in
the proper mode ARC/TIG. If you are TIG Welding check to see if
you have the proper TUNGSTEN and FILLER ROD.
Tungsten is
Melting or Being
Consumed
Quickly
Low Argon Gas flow. Check the Argon Gas flow. Turn up post
flow. Incorrect Tungsten or Incorrect Tungsten Size. Possible
small size shield cup. Read selecting the right tungsten on
www.longevity-inc.com/resources
Contaminated
Tungsten
If the Tungsten is dipping or melting inside the weld. Use
larger tungsten and fewer amps on the unit. Sharpen tungsten.
Poor Weld Quality
Remember to clean welding material prior to welding with
acetone. Practice on the form and technique. Use the right tungsten
and filler rod.
