CUTTING ISSUES
Inspect the work clamp and its lead for damage, repair or
replace as necessary.
Improper cutting technique.
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.
Plasma torch may not be in contact with
the workpiece.
Be sure to physically drag the cutting nozzle on the
workpiece as you cut.
Poor cut quality.
Improper use of Plasma torch.
Review operating instructions.
Plasma torch parts are worn out.
Examine the consumables for wear and replace worn parts
with new YesWelder consumable parts.
Moisture or oil in air supply.
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.
Insufficient cut pene-
tration.
Workpiece is too thick.
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.
Cutting speed too fast.
Decrease your torch travel speed.
Ensure that Plasma torch head is perpendicular to the
workpiece.
Plasma torch is too tilted.
Choose thinner workpiece material within the operational
limits of the plasma cutting machine.
Cutting current too low.
Turn current setting up.
Ensure plasma cutting machine has proper input power.
If used, eliminate or reduce length of extension cord.
Plasma torch parts are worn out.
Examine the consumables for wear and replace worn parts
with new YesWelder consumable parts.
Non-genuine manufacturer's parts.
Use only genuine YesWelder consumables for optimum per-
formance.
