TROUBLE EXPERIENCED POSSIBLE REASONS RECOMMENDED SOLUTION
Tilted cut edge angle (not
perpendicular).
PLASMA TORCH position
not correct.
Ensure that PLASMA TORCH is perpendicular to the
workpiece.
Workpiece thickness is near
the capacity of the machine.
Cut thinner material. 3/8” thick material cuts will not
have a clean cut edge.
Asymmetric wear of
CUTTING TIP hole and/or
wrong assemblage of the
PLASMA TORCH parts.
Check PLASMA TORCH consumables for wear and
proper installation.
Examine the consumables for wear and replace worn
parts with new Forney consumable parts.
Excessive wear of the
CUTTING TIP (D) or
ELECTRODE (B).
Air pressure too low. Inspect air compressor, air lines, and filters for proper
operation.
Inspect consumables for obstructions and proper
installation.
Exceeding plasma cutting
machine capability
(material too thick).
Choose thinner workpiece material within the operational
limits of the plasma cutting machine.
Moisture or oil in air supply. Excessive humidity or oil from the compressor may be
contaminating the air supply. Install a moisture filter in the
air supply line prior to machine.
Improperly assembled or
loose PLASMA TORCH
consumables
Check PLASMA TORCH consumables for proper
installation.
Damaged PLASMA TORCH
consumable.
Check PLASMA TORCH consumables for damage and
replace if damaged.
Non-genuine
manufacturer’s parts.
Use only genuine Forney consumables for optimum
performance.
Overheating.
Exceeding duty cycle of the
plasma cutting machine.
Allow unit to cool with internal fan running, once cool
reduce arc cutting time to below duty cycle rating of the
plasma cutting machine.
