5-4. Plasma Cutting System Practices

Pulling rather than pushing the torch

makes cutting easier. Use a proper guide

or template for accurate cutting operations.

! The pilot arc starts immediately

when trigger is pressed.

Maintain approximately a 90

 angle to the

workpiece surface for proper cutting results.

Always connect work clamp to a clean,

paint-free location on workpiece, as close to

cutting area as possible.

90

DO NOT start pilot arc without cutting or

gouging as this shortens the service life

of the nozzle and electrode.

Sparks should pass through the workpiece

and out the bottom when cutting.

If sparks flare back from surface, this

usually is an indication that either travel

speed is too fast or amperage is set too low.

When doing extended (non-shielded)

cutting, maintain approximately 1/16 in.

standoff between electrode and surface.

1/16 in.

(1.6 mm)

DO NOT put pressure on shield when

drag cutting; instead, slide shield along

the surface for proper cutting results.
