speed of cut toward minimizing dross

buildup on underside of cut. Experiment

with adjusting current and speed to

minimize dross.
For more specific issues regarding quality

of cuts and general operation, go to the

Troubleshooting section of this manual.

MAINTENANCE

1.

Each Use

Each time you use the plasma cutter;

check the Torch, Tip/Nozzle, Electrode,

Swirl Ring and Shield Cup.
Inspect Torch for any wearing, cracks or

exposed wires. Replace or repair before

use.
A worn Torch Tip/Nozzle contributes to

reduced speed, voltage drop and crooked

cuts.

A worn Tip/Nozzle is indicated by an

elongated or oversized orifice.
The face of the electrode should not be

recessed more than 1/8”. Replace if worn

beyond this point.
If the Shield Cup does not go on easily,

check the threads.

2. Weekly

Check for proper fan operation

Blow or vacuum dust and dirt out of the

entire machine and the air filter.

TROUBLESHOOTING

PROBLEM

CAUSE

SOLUTION

Torch will not come on

Power Switch Off

Air supply is compromised

Workpiece Ground Clamp

not attached.

Turn Power Switch to the On Position

Another indication of this is a more green flame

Check air supply.

Attach to workpiece or to steel table with work

piece securely clamped to table.

Sparks are shooting upward

Instead of down through the

Material.

Plasma Torch is not piercing

the material.

Torch may too far away

from stock

Material may not be

grounded properly

Travel speed too fast

Increase current.

Decrease the distance of your torch to stock

Check connections for proper ground.

Reduce speed

Beginning of cut not

completely pierced

Possible connection problem Check all connections

Dross build-up on parts of

cuts

Tool/Material building up

heat

Allow material to cool then continue cut.
