4.2 Cutting Preparation 1、Connect the power cable to electrical outlet (the input voltage, refer to the section 3). 2、Connect the air hose to the air supply equipment and set pressure to ~60 psi (4.2 bar). 3、Connect the earth cable to the workpiece not being removed with cut. 4、Make certain operator is wearing proper safety glasses (1.7-6.0 DIN) gloves and protective clothing.
§5 Maintenance 5.1 Cutting Torch Maintenance Plasma cutting torches use ionized air (plasma) as the arc that “melts” the metal and is pushed away by the compressed air. This plasma arc exceeds 50,000°F (28,000°C) when it is pushed through the .030”-.040” (0.8-1.0mm) hole in the berylium copper cutting tip. Considering these extreme temperatures, it is easy to understand the need to replace tips &...
5.2 Trouble Shooting Principle WARNING There are extremely dangerous voltage and power levels present inside this unit. Do not attempt to diagnose or repair unless you have had training in power electronics measurement and troubleshooting techniques. A. The cutting torch fails to ignite the arc when torch trigger depressed, DC pilot light on. 1.
G. No gas flow with the power lamp ON and fan operating Gas not connected or pressure too low, check gas connections. Adjust gas pressure to proper setting. Faulty components in unit, return for repair or have qualified technician repair. L.
