PILOT ARC DISCUSSION

The PRO-CUT has a smooth, continuous pilot arc. The pilot arc is only a means of transferring the arc to the workpiece for cutting. Repeated pilot arc starts, in rapid succession, is not recommended as these starts will generally reduce consumable life. Occasionally, the pilot arc may sputter or start intermittently. This is aggravated when the consumables are worn or the air pressure is too high. Always keep in mind that the pilot arc is designed to transfer the arc to the work- piece and not for numerous starts without cutting.

When the pilot arc is started, a slight impulse will be felt in the torch handle. This occurrence is normal and is the mechanism which starts the plasma arc. This impulse can also be used to help troubleshoot a "no start" condition.

PROCEDURE RECOMMENDATIONS

When properly used, plasma arc cutting or gouging is a very economical process. Improper use will result in a very high operating cost.

General - In All Cases

•Follow safety precautions as printed throughout this operating manual and on the machine.

Thin Gauge Sheet Metal:

Torch Standoff

Machine Output Setting

DRAG thru 1/16"

Output Setting

Standoff

Min. thru Mid. Range

Output set below mid-range.

•The nozzle may be dragged on the metal sur- face, touching it lightly to the surface after pierc- ing a hole. Current control should be set below the mid range.

•Do not allow cable or body to contact hot sur- face.

Thick Sections of Metal

Torch Standoff

Machine Output Setting

1/8" thru 3/16"

Output Setting

Standoff

Mid. thru Max. Range

Output set above mid-range.

•The best quality and consumable life will be obtained by holding the torch off the surface about 3/16". Too long an arc may compromise cut quality and consumable life. The nozzle should NOT be dragged on the work.

•Use of the S22151 Drag Cup will maintain the proper standoff. The only reason not to use the Drag Cup when the output control is set above mid-range is in special, tight corners. Always hold at least a 1/8" standoff in those situations.

•If piercing is required, slowly lower the torch at an angle of about 30° to blow the dross away from the torch tip and slowly rotate the torch to a vertical position as the arc becomes deeper. This process will blow a lot of molten metal and dross. Be careful! Blow the dross away from the torch, the operator and any flammable objects.

•Where possible, start the cut from the edge of the work piece.

•Keep moving! A steady speed is necessary. Do not pause.

•Do not allow torch cable or body to contact hot surface.
