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.

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 as this

shortens the life of the tip 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 travel

speed is too fast.

DO NOT put pressure on shield when

drag cutting; instead, slide shield along

the surface for proper cutting results.

Wt

.

Do not connect work clamp to the portion
of the workpiece that will fall when cut.

!

The pilot arc starts immediately

when trigger is pressed.
