Troubleshooting
Common Plasma Cutting Issues
TROUBLE:
CAUSE/SOLUTION
NO.
Air flows but arc does not start within 2
-
3 seconds.
Check consumables for wear and tightness. Check fuse.
Check Air Pressure. Sticky or slow spring/piston on torch blow back mechanism.
Release trigger and try again.
1.
Air flows but pilot arc does not start or spark but arc starts when
Fuse blown. Replace with 30 A automotive type, slow blow. PCB issue.
2.
Will not start arc.
Air Pressure too low or too high. Torch electrode/blow back mechanism stuck in rear
position (Clean and relubricate or replace head). Missing Swirl Ring (usually happens
after consumable change).
3.
Pilot arc will not light. Arc will start when torch is drug on the metal.
Possible missing swirl ring. Pilot Arc wire is disconnected.
4.
Pilot arc will not transfer and amps read approximately 25
-
27 amps
while switch is held. (Arc barely cuts or only
“
scratches
”
the surface
of the metal or cut is extremely slow on thin materials.)
Check work clamp connection. Make sure rust is removed from work clamp contact
area. Faulty Clamp. Arc continuity is not being sensed. If these steps do not correct
the issue, contact Everlast.
Arc Sputters.
Inadequate air flow or air pressure. Improperly sized nozzle. Change to nozzle/Tip with
smaller diameter orifice as amps are lowered. Readjust air pressure. Loose consuma-
bles. Check tightness. Worn Consumables
5.
Consumables are dirty, smutty looking upon inspection. Premature
wear on consumables. Shortened consumable life. Tips are melt-
ed looking.
Moisture, oil contamination of consumable. Wrong consumables. Poor quality aftermar-
ket consumables. Drag cutting with wrong consumables. Wrong cutting technique.
6.
Premature wear on consumables. Short consumable life. Uneven
wear of consumables, melting of cup.
Moisture, oil contamination of consumable. Excessive pilot arc time. Improper cutting
technique. Wrong piercing technique.
7.
Arc will not start with pilot arc or by drag/scratch starting nozzle
directly on metal. Machine runs.
Torch cup is loose, safety contact pins dirty or not making contact with cup face. Torch
switch wire is loose. Problem with Central connector. Torch is not properly connected.
IGBT or PCB bad, contact Everlast.
8.
Over current/Duty cycle Error Code. 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 and remove
excess/undersized extension cords. Operated on
“
dirty power
”
generator and unit has
failed.
9.
Unstable arc at lower amps.
Nozzle orifice size is too large. Use nozzle with smaller orifice. Air pressure too high or
too low. Poor work clamp connection.
10.
Arc tries to start but irregular, dancing arc and/or arc melts through
side of nozzle.
Missing swirl ring, or worn electrode or both. Check and replace. Make sure swirl ring
is not cracked.
11.
Arc will try to start if touched to the metal, but no air flow while
switch is pressed.
Stuck or dirty solenoid valve. Loose solenoid wire connection. Bad PCB. Contact
Everlast.
12.
Air flows continuously. Erratic or unpredictable shutting off of air
after post flow time has expired.
Place switch into
“
normal
”
or
“
cut
”
mode. Reduce post flow time. Solenoid is stuck.
Contact Everlast.
13.
Excessively Beveled Cut.
Worn consumables, too high of stand
-
off height.
14.
Cup and/or nozzle is melting or cracking.
Improper cutting technique/excessive piercing.
15.
Power input circuit breaker trips repeatedly.
Improperly sized circuit. Internal issue. Contact Everlast.
16.
Arc
“
Blows Out
”
when ready to cut.
Too high of air pressure. Wrong size consumable for amperage being used.
