6-4. Plasma Cutting System Practices
! The pilot arc starts immediately
when trigger is pressed.
Always connect work clamp to a clean,
paint-free location on workpiece, as close to
cutting area as possible.
. Set switch to either cut or gouge
depending on desired process.
DO NOT start pilot arc without cutting or
gouging as this shortens the service life
of the nozzle and electrode.
CUT GOUGE
. Connect work clamp to portion of workpiece
that does not fall away after being cut.
. For more information, go to MillerWelds.com.
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.
90°
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 1/8 in.
standoff between electrode and surface.
1/8 in.
(3.2 mm)
DO NOT put pressure on shield when
drag cutting; instead, slide shield along
the surface for proper cutting results.
