 PROBLEMS IN PLASMA CUTTING
TROUBLESHOOTING PLASMA CUTTING
PROBLEMS
(SYMPTOMS) PROBLEM CAUSE RECOMMENDED ACTION
Torch does not
work
 Power switch off
 Air supply is compromised
 Ground clamp & cable is not attached
 Turn power switch “ON”
 Check air supply
 Attach the ground clamp & cable securely
to work-piece or steel table with
work-piece
Sparks shoots
upward instead of
downward
through the
material
 Plasma cutting torch is not piercing
the material
 Torch may be too far away from stock
 Material may not be grounded
properly
 Travel speed is too fast
 Increase current
 Decrease the distance of your torch to
stock
 Check connections for proper grounding
 Reduce speed
Dross build-up on
parts of cuts

Tool and material build up heat
 Cutting speed is too slow or current is
too high

Torch parts are worn
 Allow material to cool down and then
continue to cut
 Increase speed or reduce current until
dross is reduced to minimum
 Inspect and repair/replace worn parts
Insufficient
penetration
 Torch is tilted too much
 Metal is too thick
 Torch parts are worn
 Make tilt adjustments
 Several passes may be necessary
 Inspect and repair/replace worn parts
Consumables
wear out quickly
 Exceeding unit capability
 Improperly assembled torch
 Inadequate air supply: pressure is too
low
 Faulty air compressor
 Material is too thick. Increase angle to
prevent blowing back into torch tip
 Assemble torch correctly referring to
Installation

Check air filter, increase air pressure
 Check air compressor operation
