Problem Solving:
Care must be taken to not overtighten the air/gas fitting on the Cut 40. This gas receptacle is located on the back of
the unit.
If overtightened. you risk the possibly of shifting the air/water separator inside the unit. If this happens it may cause the
relief valve on the air/water separator to be depressed resulting in a failure to pressurize the unit. A good indication is the
sound of leaking air when trying to use the unit. If the air/water separator has shifted and the system will not pressurize the
problem is easily corrected by re-centering the air/water separator relief valve in relation to the vent hole located on the
bottom of the unit. Loosen the gas receptacle on the back of the unit to its original location allowing the air/water
separator to be centered in its relief hole on the bottom of the unit.

Problem
:
Cause and Solution
Machine won't turn on.
Check cords and plug wiring. Occasionally a terminal screw will loosen after
installation and use. Check for proper wiring at plug and receptacle. Check
household circuit breaker. If no fault is found, contact us for support.
Machine runs, but doesn't cut.
Check for a good work clamp connection. Make sure work piece cable and plasma
torch is securely fastened to lug. Check that the Track torch Auto/Standard switch
is in the correct position for type of use desired. Check
household circuit breaker
.
Electrodes and tips are rapidly
consumed.
Inadequate air flow. Water in air supply. Poor cutting technique. Return to stand
off cutting of no more than 1/8“, not less than 1/16”. Check and tighten
consumables.
Heavy slag on the underside of the
cut with complete cut through.
Travel speed too slow. Either increase cutting speed or reduce cutting
amperage to fit metal thickness. Too much standoff (more than 1/8”). Worn
consumables. Low air pressure. (Do not exceed 70 psi)
Cut is beveled on one side.
Plasma cutters tend to leave a slightly beveled side (up to 5°). However,
decreasing the standoff and increasing air pressure can help reduce or
eliminate problems. Worn Consumables. Replace consumables.
Air is heard escaping inside unit.
Over pressurized supply line. Internal leakage around air fittings. Consult
with support for repair instructions if needed. No air supply.
Cut quality is poor or irregular.
Check and adjust settings. Increase or decrease air pressure. Check for
consumable wear and tightness.
Unstable Plasma Arc.
Poorly grounded unit or worn electrode.
Surrounding lights or electronic
equipment malfunctions.
Use high frequency ground connected to an exterior ground rod to drain
electromagnetic frequencies. Use a shielded wire to drain if necessary. Consult
local electrician/codes.
