workpiece.
Improper cutting technique.

POSSIBLE CAUSE COURSE OF ACTION
Clean the area where the work clamp attaches to the
workpiece to ensure a good metal to metal connection.
Inspect the work clamp and its lead for damage, repair or
replace as necessary.
1. Brace the cutting hand to steady cutting hand, provides
freedom of movement in all directions and helps maintain a
constant 1/16"to 1/8" standoff.
2. Place the torch close and start cut from the edge of the
metal with a roll 45-to-90 degree roll in case the sparks
blow up into the torch.
Be sure to physically drag the cutting nozzle on the
workpiece as you cut.
Review operating instructions.
Examine the consumables for wear and replace worn parts
with new YesWelder consumable parts.
Excessive humidity or oil from the compressor may be con-
taminating the air supply. Install a moisture filter in the air
supply line prior to machine.
Decrease your torch travel speed.
Ensure that Plasma torch head is perpendicular to the
workpiece.
Choose thinner workpiece material within the operational
limits of the plasma cutting machine.
Turn current setting up.
Ensure plasma cutting machine has proper input power.
If used, eliminate or reduce length of extension cord.
Examine the consumables for wear and replace worn parts
with new YesWelder consumable parts.
Use only genuine YesWelder consumables for optimum per-
formance.
Check for obstructions blocking air flow and ensure that
there are 12 inches of clearance between any obstacles
and the vents on all sides of the machine.
