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.
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.

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.

STICK Welder
Having a Hard Time
Striking an Arc

Check the ground. Check the workpiece and clean it. Increase the Arc Force
on the unit.
STICK Welder
Producing Poor
Quality Welds

Use the proper rod and polarity.
