THIS MANUAL.
ELECTRIC SHOCK can be fatal
 Have a qualified electrician install and service this equipment.
 Turn the input power off at the fuse box, disconnect or unplug supply lines and allow machine to
sit for five minutes minimum to allow the power capacitors to discharge before working inside this
equipment. Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge
before working inside this equipment.
 Do not touch electrically hot parts.
 INPUT FILTER CAPACITOR DISCHARGE PROCEDURE
The machine has internal capacitors that are charged to a high voltage during power-on conditions. This
voltage is dangerous and must be discharged before the machine can be serviced. Discharging is done
automatically by the machine each time the power is switched off. However, the user must allow the machine
to sit for at least 5 minutes to allow time for the process to take place.
 ROUTINE MAINTENANCE
Routine maintenance will prevent metal powder from accumulating near the aeration fins and over them.
 Each Use
Each time you use the plasma cutter; check the Torch, Tip/Nozzle, Electrode, Swirl Ring and Shield Cup.
Inspect Torch for any wearing, cracks or exposed wires. Replace or repair before use. A worn Torch
Tip/Nozzle contributes to reduced speed, voltage drop and crooked cuts. A worn Tip/Nozzle is indicated by
an elongated or oversized orifice. The face of the electrode should not be recessed more than 1/8”. Replace
if worn beyond this point. If the Shield Cup does not go on easily, check the threads.
 Weekly
Check for proper fan operation.
Blow or vacuum dust and dirt out of the entire machine and the air filter.

Carry out the following periodic controls on the power source
 Clean the power source inside by means of low pressure compressed air.
 Check the electric connections and all the connection cables.
 Always use gloves in compliance with the safety standards.
