No cutting power
Difficult to maintain
cutting arc
Build up of metal on
underside of work piece
POSSIBLE CAUSE
1, Unit not plugged in
2. Faulty Power Switch
3. Faulty Power Cord
1. Worn electrode
1. Thermal Overload
Protection activated
1. Pneumatic Overload
Protection activated
1. Worn nozzle
2. Moisture in air supply
3. Duty Cycle exceeded
4. Low voltage to Plasma
Cutter
1. Worn nozzle
2. Worn electrode
3. Moisture in air supply
4. Low air supply
5. Bad workpiece ground
connection
1. Torch angle and spacing
incorrect
2. Worn consumables 2.
3. Travel speed too slow 3.
Difficulty penetrating material 1. Workpiece is too thick 1.
2. Worn consumables 2.
3. Travel speed too fast 3.
4. Low air supply 4.
Arc goes out while cutting 1. Travel speed too slow 1.
POSSIBLE REMEDY
1, Plug unit in to grounded
220V power source
2. Replace Power Switch
3. Replace Power Cord
1. Replace electrode
1_ Let unit cool for at least 10
minutes and try again
1_Check air supply. (See
CONNECTING THE AIR
SUPPLY)
1. Replace nozzle
2. Drain moisture from Air
Regulator Filter
3. Let unit cool for at least 10
minutes and try again
4. Check AC power source
voltage-correct if needed
1. Replace nozzle
2. Replace electrode
3. Drain moisture from Air
Regulator Filter
4. Make sure air regulator is
set to 65 psi
5. Make sure ground
connection is clean of oil,
dirt, rust, etc.
1. Hold torch at 90 degree
angle to workpiece,
approximately 1/8 inch
from workpiece.
Replace as necessary
Increase travel speed
Use thinner workpiece
Replace as necessary
Decrease travel speed
Make sure air regulator is
set to 65 psi
Increase travel speed
