105A Nozzle and Electrode life when cutting 20mm steel

[supertux]

Hello. i use PMX 105 with consunable 105A Nozzle and standart electrode, cutting steel 20mm. How long life Nozzle and Electrode? how many pierces? Thanks.

If pierces are done at the correct pierce height and pierce delay specs as listed in the operators manual you will get as many as 300 pierces. One pierce too close on that thickness can damage the nozzle orifice....so the height control functions are critical.
