6-4. 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
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.
