Zusammenfassung:A method for extending the life of a torch consumable comprising: providing a first fluid line for supplying a plasma gas to the torch; positioning a programmable control valve in the first fluid line adjacent the torch to control a flow of the plasma gas; and manipulating the programmable control valve thereby a) controlling the flow of the plasma gas to the torch during operation of the torch; and b) compensating for a volume in the first fluid line between the proportional solenoid control valve and the torch.
