Page 4: Installation
2 INSTALLATION After connecting electric power and compressed air, the machine is ready for use. If installing machine on 110V supply the required fuse size is 32A. NOTE: at least 7.5 kVA should be available from the generators exclusively for the plasma cutting system. If available power is lower it may result in major damage to the power source. -
Page 5: Operating Instructions
3 OPERATING INSTRUCTIONS Check that the machine has been properly connected to power supply and compressed air according to chapter 2, INSTALLATION. Check that the torch is fitted with appropriate consumables for the job at hand. Connect the return clamp directly onto the work piece, ensuring that a good contact is obtained. If necessary, clean the surface from paint, rust, dirt, etc. - Page 6 Piercing Rest the nozzle on the work piece at 45° angle Press the trigger-switch on the torch handle. Pilot arc strikes. After cutting arc starts, slowly and in one smooth movement, straighten torch back up until 90° angle to plate. Start moving torch across plate when observing that the arc penetrates.

Page 9: Maintenance
5. MAINTENANCE DAILY Inspect and, if necessary, change the torch consumable parts. Note: Electrode and nozzle must be changed at regular intervals, as a general guideline after 2 hours continuous use, or after 200 starts. Always replace the electrode if the centre has a pit more than 2 mm (1/16” deep). Replace the nozzle if the opening is deformed or clearly oversized. -

7. SAFETY INSTRUCTIONS All endangerments through plasma cutting are related with the process itself. Endangerments may occur due to: - High contact voltage - HV ignition - Electromagnetic interferences - Heat and light radiation - Gases, fumes and smoke - Noise - Hot metal and spatter - Handling of pressure cylinders The Plasma Cutting Machine has been developed in conformity with following standards:... - Page 12 Recommendations to classify the environment (EN 60974-10): Before the installation takes place the user has to evaluate the environment for electromagnetic problems and to take into consideration: Other mains supplies, control cables, signal and telecommunication lines along, above, below or beside the installation.

8. SERVICE SECTION 8.1 Torch Check. Check that the consumables are in working order and correctly mounted in the torch. Check the parts in place pins on the torch head, check that the pins springs are OK by pushing them inwards they should feather easily. - Page 14 Disconnect the power source from mains power supply. Remove the handle and cover plate from the power source 8.2 Torch connection test. 1. Torch trigger. 2. Parts in place connection (PIP). 3. Negative lead (Electrode). 4. Pilot lead (Nozzle). 5. Air connection. Check torch trigger by measuring on the torch trigger connections with summer or resistance measurement and press the start trigger on the torch.
- Page 15 Cont. 8.2 Torch connection test. Check the pilot lead (nozzle) by measuring between the pilot lead connection and the nozzle with summer or resistance measurement. Make sure the consumables are correctly mounted. If no connection repair or replace the torch. Check the negative (electrode) lead by measuring between the negative lead connection and the electrode with summer or resistance measurement.
- Page 16 8.4 Replacing the torch. Disconnect the power source from mains power supply. Disconnect procedure Remove the straps. Disconnect the air hose by pushing down on the push in coupling and pulling the hose out. Disconnect the trigger leads, PIP leads, pilot lead and negative lead. Please note that the negative lead is run through the blue LEM module on the PCB.
- Page 17 Cont. 8.4 replacing the torch. Run the negative lead through the blue LEM module on the PCB and connect to the connector. Connect the pilot lead and trigger/PIP leads. Connect the air hose, shorten it if necessary. Put some straps on the cables to keep them in place and tighten the cable gland. Perform the torch function test as described in 8.3 Revision date: 15-08-10 Page 17 of 28...

- Page 19 8.6 Board diagnostic. Disconnect the power source from mains power supply. Discharge the capacitors by connection a resistor 1kΩ 7W between the screws shown on the picture, or wait at least 5min before proceeding. Insulation check. Measure the resistance between the screws marked in red and earth (PE) the resistance should have a high value in the mega ohm range, if a value is low or short is measured replace the board.
- Page 20 Cont. 8.6 Board diagnostic. Check the start resistor. Measure the start resistor it should have a value of 47ohms. If the resistor is broken you can try to replace it. Be careful the resistor might be damaged as a consequence, there might be damages on the board or power module.
- Page 21 Cont. 8.6 Board diagnostic. IGBT Control. Measure the PFC diode and IGBTs, correct value is approx. 0.350V. If there is a short or low value replace the PCB. Revision date: 15-08-10 Page 21 of 28...
- Page 22 Cont. 8.6 Board diagnostic. Relay control check. Connect the machine to mains supply. Check that the two green LED marked in red light up when switching on the power supply indicating the signal ON to the relays. Auxiliary power supply check. Check that the LED indicating the +16 and +24V on the auxiliary power supply lights up.
- Page 23 8.7 Replacing the power module. Disconnect the power source from mains power supply. Discharge the capacitors by connection a resistor 1kΩ 7W between the screws shown on the picture, or wait at least 5min before proceeding. Remove the torch according to 8.4. Disconnect the mains supply cable, earth lead, fan and pressure guard from the PCB.
- Page 24 Cont. 8.7 replacing the power module. Disconnect the air hose for the manometer from the T-coupling and loosen the fan by pushing outward on the plastic holders. Put the power supply on its side and unscrew the rubber feet and the two middle screws. Raise the power supply and carefully lift out the power module.
