Page 8: Compressed Air Connection
Compressed air connection Prepare a clean, dry compressed air or nitrogen distribution line with the following minimum characteristics. Air pressure: 6-8 bar Flow rate: 220 l/min for H.70 (HTM 70) and EP-105 (EPM 105). Air hose diameter: Min. 8mm for H.70 (HTM 70) and EP-105 (EPM 105). IMPORTANT: Failure to follow these instructions may cause overheating or damage to the torch. - Page 9 NOTE: the tip, diffuser and electrode are held together in place by the nozzle. Position the torch with the nozzle facing upward to prevent these parts from falling when the nozzle is removed. ATTENTION: Wait until the torch has cooled down completely before replacing the consumable parts to avoid damaging the torch body.

Page 16: Grid Cutting
Grid cutting From the PROCESS SELECTION MENU; if GRID CUTTING is selected, the following screen appears: 23 C Grid Cutting HOLD for 3” to PROCESS SELEC. Set the current by turning Encoder E1. Gouging Plasma gouging is a process involving the melting and then removal of material. To carry out this type of processing, the nozzles of the torch and its gas diffusers are usually different and the torch must be held in a tilted position. -
Page 17: Cnc Cutting
CNC cutting From the PROCESS SELECTION MENU; if CNC CUTTING is selected, the following screen appears: 23 C CNC Cutting HOLD for 3” to PROCESS SELEC. Set the current by turning Encoder E1.
