APPENDIX 13: RECOMMENDED ROUTINE MAINTENANCE<br />
SCHEDULE FOR LIQUID COOLED PLASMA CUTTING<br />
SYSTEMS<br />
This schedule applies to all types of liquid cooled plasma cutting systems. Some systems will not have all the parts<br />
listed and those checks need not be performed.<br />
NOTE<br />
The actual frequency of maintenance may need to be adjusted according to the operating environment.<br />
Daily Operational Checks or Every Six Arc Hours:<br />
1. Check torch parts, replace if damaged.<br />
2. Check plasma and secondary supply and pressure/flow.<br />
3. Purge plasma gas line to remove any moisture build-up.<br />
4. Check deionizer bag/cartridge, replace if color is predominantly yellow.<br />
5. Check coolant pressure (100 - 120 psi).<br />
Weekly or Every 30 Arc Hours:<br />
1. Check fan for proper operation and adequate air flow.<br />
2. Blow or vacuum dust and dirt out of the entire machine.<br />
CAUTION<br />
Do not blow air into the power supply during cleaning. Blowing air into the unit can cause metal particles to<br />
interfere with sensitive electrical components and cause damage to the unit.<br />
Six Months or Every 720 Arc Hours:<br />
1. Remove and clean in-line filter screens.<br />
2. Check cables and hoses for leaks or cracks, replace if necessary.<br />
3. Check all contactor points for severe arcing or pits, replace if necessary.<br />
4. Check all pillow blocks and bearings, clean and lubricate if necessary.<br />
5. Check fan, pump and pulley belts for wear or cracking, replace if necessary.<br />
Twelve Months or Every 1500 Arc Hours:<br />
1. Drain coolant, fill with distilled water, turn on main power switch and let machine run for approximately 30<br />
minutes.<br />
WARNING<br />
DO NOT energize the Torch.<br />
Drain distilled water and replace with Thermal Arc Coolant. Use Extra-Cool TM Coolant (Catalog # 7-3580) or Ultra-Cool TM<br />
Coolant (Catalog # 7-3581) for environments below +10° F (-12° C).<br />
2. Check radiator fins, clean and comb out if necessary.<br />
3. Repeat six month maintenance.<br />
