5-3. 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.
Y The pilot arc starts immediately
when trigger is pressed.
