TROUBLE EXPERIENCED
Tilted cut edge angle (not
perpendicular).
Excessive wear of the
CUTTING TIP (D) or
ELECTRODE (B).
Overheating.
POSSIBLE REASONS
PLASMA TORCH position
not correct.
Workpiece thickness is near
the capacity of the machine.
Asymmetric wear of
CUTTING TIP hole and/or
wrong assemblage of the
PLASMA TORCH parts.
Air pressure too low.
Exceeding plasma cutting
machine capability
(material too thick).
Moisture or oil in air supply. Excessive humidity or oil from the compressor may be
Improperly assembled or
loose PLASMA TORCH
consumables
Damaged PLASMA TORCH
consumable.
Non-genuine
manufacturer's parts.
Exceeding duty cycle of the
plasma cutting machine.

RECOMMENDED SOLUTION
Ensure that PLASMA TORCH is perpendicular to the
workpiece.
Cut thinner material. 3/8" thick material cuts will not
have a clean cut edge.
Check PLASMA TORCH consumables for wear and
proper installation.
Examine the consumables for wear and replace worn
parts with new Forney consumable parts.
Inspect air compressor, air lines, and filters for proper
operation.
Inspect consumables for obstructions and proper
installation.
Choose thinner workpiece material within the operational
limits of the plasma cutting machine.
contaminating the air supply. Install a moisture filter in the
air supply line prior to machine.
Check PLASMA TORCH consumables for proper
installation.
Check PLASMA TORCH consumables for damage and
replace if damaged.
Use only genuine Forney consumables for optimum
performance.
Allow unit to cool with internal fan running, once cool
reduce arc cutting time to below duty cycle rating of the
plasma cutting machine.
