19. Preparations for cutting

Equipping the torch
Fit a plasma nozzle according to manufacturer's instructions respectively the at the main switch or step switch
given data into the torch. If the hole of the nozzle is too big, the power and quality of the cut decreases. If it is too
small, the plasma nozzle is overstressed and gets damaged.
Plasma nozzle and electrode are wear parts. A plasma nozzle with a badly burnt-out hole and an electrode with a
large penetration crater involves worse cutting quality and striking characteristics. These parts must be
exchanged by original wear parts.
At the exchange of wear parts take care that they are tightened fastly.
Recommended nozzle diameter:
Diameter
Connection to work piece
Connect work piece with work piece cable to corresponding socket. Pinch work piece terminal to work piece,
choosing an appropriate spot without paint or rust for good conductivity.
