Maintenance & Servicing

General Maintenance

DISCONNECT INPUT POWER CABLE (3) FROM THE ELECTRICAL OUTLET AND

WAIT FOR THE PLASMA TORCH (9) TO COOL BEFORE REMOVING THE SHIELD

CUP (E) OR PERFORMING MAINTENANCE.

CAUTION! Maintenance can only be carried out on the unit if the person in charge of this operation has the

necessary technical knowledge and the correct tools. If this is not the case, contact your nearest service center.

CAUTION! Never access inside the machine (panel removal) or touch the torch head (disassembly) without

having disconnected INPUT POWER CABLE.

ANY INSPECTION PERFORMED UNDER VOLTAGE INSIDE THE MACHINE OR

INSIDE THE PLASMA TORCH MAY CAUSE SEVERE ELECTRIC SHOCKS CAUSED BY

DIRECT CONTACT WITH PARTS UNDER VOLTAGE.

CAUTION! Use only dry compressed air for cleaning. Do not point the jet of air at the electronic circuits

contained within this plasma cutting machine.

Your plasma cutting machine must routinely receive maintenance to keep the system in optimal working condition

and to provide long-term value for your investment. It is recommended to inspect the unit every 3-4 months

(depending on the frequency of use).

• Use compressed air to remove any dust deposits.

• The torch SHIELD CUP (E) and CUTTING TIP (D) should be periodically inspected for wear or damage.

• Replace the CUTTING TIP if the orifice becomes damaged or enlarged.

• If consumable surfaces are particularly oxidized, clean them with an extra fine abrasive.

• Replace the AIR DIFFUSER RING (C) if it is burned or cracked.

• Replace the ELECTRODE (B) when the crater on the end surface is approximately 1/16”.

FAILURE TO MAINTAIN THE PLASMA CUTTING MACHINE, CONSUMABLES AND THE

WORKING ENVIRONMENT WILL DECREASE THE SYSTEM’S PERFORMANCE AND PRODUCE

RESULTS BELOW OPTIMAL PERFORMANCE LEVELS.

FREQUENCY PERIODIC MAINTENANCE TO BE PERFORMED

Each Use • Check the indicator lights/LEDs and correct any fault

conditions.

• Check & clean SHIELD CUP, CUTTING TIP, AIR

DIFFUSER RING and ELECTRODE for proper installation,

wear, damage (burns, distortions or cracks), dirt, debris

and restricted holes.

Weekly • Verify the operation of the SHIELD CUP shut-down

system. (Remove SHIELD CUP and pull trigger. Pilot arc

should not start.)

3 Months • Check for and replace any cracked or damaged parts.

• Check the torch trigger guard for damage.

• Check TORCH BODY (A) and trigger for wear, exposed

wires or damage, replace as required.

• Check outer covering of all cables for wear, repair or

replace as required.

6 Months • Blow out or vacuum inside.
