SECTION 5 PCM-875A Plasmarc Cutting System CAUTION Maintenance The torch requires good electrical contact between the electrode seat and electrode holder. If good contact is not maintained, then the resulting potential difference causes internal arcing and possible torch damage. 5.3.4 Damage Caused by Loose Parts and Torch Overheating. Electrode Insulator (21373) Arc tracking indicates loose parts.
SECTION 5 PCM-875A Plasmarc Cutting System Maintenance 3. Remove the nozzle and electrode assembly from the shield and inspect for wear. The nozzle orifice should be round at both the entrance and the exit. If the nozzle orifice is worn in an oval shape or shows other signs of damage at either end, it should be replaced. The inside of the nozzle may have light gray deposits from the electrode. These may be removed with steel wool but care must be taken to remove all traces of the steel wool afterward.
SECTION 5 PCM-875A Plasmarc Cutting System Maintenance 5. Inspect the o-ring on the torch. If it shows signs of wear or damage, replace it. If it is dry, lubricate it with a thin film of lubricant supplied with spare parts kit Inspect o-ring of torch 6. Install the nozzle and the electrode assembly into heat shield and thread heat shield onto torch. The shield should be tightened fully to insure good electrical contact for electrode and nozzle.
SECTION 5 PCM-875A Plasmarc Cutting System Maintenance 5.3.7 Removal and Replacement of the Torch Body ! WARNING Make sure that the power source has been turned off and that the power cable has been unplugged at the wall receptacle before proceeding. PT-20AMX Torch 1. Cut and remove the shrink wrap at the back end of the torch handle. Unscrew the handle from the torch body and slide it back onto the torch cable assembly in order to expose the torch connections. 2.

SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.1 Troubleshooting PCM-875A Plasmarc System ! WARNING Electric Shock Can Kill! Ensure that all primary power to the machine has been externally disconnected. Open the line disconnect switch or circuit breaker before inspection, maintenance or repair inside power console. Match the problem with the conditions below.
SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.2 Troubleshooting guide for PCM-875A Plasmarc System 6.2.1 Power Light (PL1) does not come on · Visually inspect the machine for damage. · Check if the cooling fan is running. If not running, check the following: § § Check if machine input power is still connected. Measure input power at the receptacle. If not present, then check the wall disconnect switch and it’s fuses. § Check fuse (F1). If it is: § Check input circuit breaker (CB1).
SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.2.3 The Power light is on, but nothing happens when the torch is signaled to fire. Fault light does not activate. NOTE: Unplug high frequency connection before attempting to work on this problem. · Check the Pilot Arc fuse (F2) located on the rear panel. An open fuse will indicate a short in the torch. If the fuse is all right, then check the following: § With the machine power on, depress the torch switch.
SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.2.4 Fault light activates when torch is signaled to fire The Fault circuit is used to monitor conditions necessary for the safe operation of the PCM-875. The fault light will glow amber under the following conditions and operations will come to a complete stop: · High/Low line voltage. The Fault Light will rapidly blink on and off (5 times per second). This indicates that the input voltage is outside the “+” or “-” 15% safe operating range rating.
SECTION 6 Fault light activates (continued) PCM-875A Plasmarc System Troubleshooting · Over Temperature. The fault light will be mostly off but will blink on for 1/10 of a second, every second. This generally indicates that the duty cycle has been exceeded. Allow the power source to cool before returning to operate. § Thermal switch may be open. It will open if the temperature at the IGBT base reaches 94oC. With the machine power off, check the continuity between P1-1 and P1-2 of the control board.
SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.2.5 Air is On but nothing happens when torch is signaled to fire. · Check pilot arc fuse located on rear panel. If it is open, nothing will happen when torch switch is depressed. · Check torch. Make sure heat shield is very tight. · Check to assure high frequency is present at torch. If not, then listen for high frequency at high frequency generator. It is located on bottom/right side of the unit. High frequency gap is set to .040".
SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.2.6 High Frequency and Pilot Arc are on but Main Arc does not transfer. · Make sure work clamp is connected to work material. · Check the torch. Replace consumables if necessary. · Make sure the current setting potentiometer is set above 10 amps. If it is, set below 10 amps, then HI FREQUENCY will go on and off at 5 sec intervals. 6.2.7 Poor Cutting Performance. · Check air supply regulator . It should be adjusted to 65-75 psig.
SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.2.9 Main arc is difficult to start. · The most common reason is worn or missing consumables. Check and replace if necessary. · Input air must be clean and dry. · Input air pressure must be between 65 - 75 psig. · Torch connections must be tight. · Work cable and clamp must be in good condition and must make a good electrical connection to the material to be cut. · If above items check OK , the problem is internal.

SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.4 PT-20AMX Torch Troubleshooting Common Cutting Problems Listed below are common cutting problems followed by the probable cause of each. If problems are determined to be caused by the PCM-875, refer to the maintenance section of this manual. If the problem is not corrected after referring to the maintenance section, contact your ESAB distributor. 6.4.1 Insufficient Penetration · Current too low. · Cutting speed too fast. · Damaged cutting nozzle.
SECTION 6 PCM-875A Plasmarc System Troubleshooting 6.4.4 Double Arcing · .Damaged Nozzle Orifice. · Low air pressure. · Damaged cutting nozzle. · Loose cutting nozzle. · Heavy spatter accumulation on nozzle. · Damaged cutting nozzle or worn electrode. 6.4.5 Uneven Arc. 6.4.6 Unstable Cutting Conditions. · Incorrect cutting speed. · Loose cable or hose connections. · Electrode and/or cutting nozzle in poor condition. 6.4.7 Main Arc Does Not Strike · Worn electrode. · Loose connections.
