Minimum rate of plasma gas flow:
gas flow rate at which the welding arc just remains stable.
NOTE!
Welding using a minimum plasma gas flow places a severe load on the plasma
nozzle and should be avoided.
Maximum welding current:
welding current that is permitted for a particular plasma nozzle, with the standard tungs-
ten electrode setting, the minimum plasma gas flow rate and depending on the cooling
unit.
Example PTW 1500:
in the case of a plasma nozzle with a diameter of 2.0 mm and a specified minimum
plasma gas flow rate of 0.25 l/min, a maximum welding current of 80 A is permitted for
the standard tungsten electrode setting.
NOTE!
Use pure argon as the plasma gas.
The limit values listed above can only be obtained using pure argon.
