Condition of Air:

The life of the plasma Electrodes and Nozzles depend upon the condition of air. The compressed air given to the Plasma cutting machine should be totally dry and oil free.

Do Not Touch The Nozzle To The Plate:

Always maintain the distance of About 3 to 4 mm between the Plasma Nozzle and the plate when using the Current level of 40 Amps. And above.

Use The Front Cap With Spacer:

We provide the front cap with Spacer Which maintains the proper distance between the Plasma Cutting Nozzle and the cutting plate. This allows the torch to rest on the work piece and Dragged along facilitate a consistent cut.

Cut at Proper Speed:

When cutting at the right speed the molten metal will blow out the bottom of the plate giving the very good cutting finish. If you are moving at a slow speed, you will observe the slow speed dross at the bottom of the cutting edge, which leads to the low consumable life. When moving too fast, high speed dross will be observed on the top surface and chances of back fire are there which may damage the nozzle. This indicates that moving too fast or too slow will reduce the Plasma consumable life.

Minimize The Pilot Arc Time:

Excess Pilot arcing creates the wear of the Consumables, so try to minimize the pilot arc timing. To do this position the plasma torch at the edge of the work piece and then start the cutting.

Move In a Direction That Gives Better Cut Finish:

Check the direction Of cutting and try to select the cutting direction for which you get the better Cut finish.

Piercing:

Do not try to start the cutting by piercing in the plate as this leads the molten metal to backfire on the plasma Nozzle thus it reduces the life of the consumables. Whenever the piercing is necessary, approach the metal at an angle and once the main arc is stricken slowly rotate the torch and bring it to the vertical position. This way the molten metal is blown away from the torch.

Operation

Proper travel speed

	Maintaining proper travel speed is key to successful cuts.
	Watch arc beneath plate (sparks lagging 15 –30° behind cut).
	Lag lines on finished cut edge should also be about 15 – 30°.

Drag cutting

	Torch front-end shielding virtually eliminates damage from touching the torch to the work piece.

Cutting expanded metal

Pilot arc controller eliminates annoying retriggering when cutting expanded materials.
