Gas plasma cutting
Use the electrode intended for technical gas; nitrogen
(N
2
) or argon/hydrogen mix (Ar/H
2
) as the plasma-
generating gas.
Characteristics:
The electrode is coated with copper.
Always use the nozzle marked 0.9. (Only exception:
contact cutting with the special contact cutting
nozzle).
ATTENTION!
The plasmacutting torch must be capable of handling
the considerable demands made upon it. Both torch
body and hose must be handled with care.
If these instructions are observed and provided the
operator posesses the necessary knowledge, the
plasmacutting torch will have a long life. Furthermore
this cutting process is extremely economical due to
the minimal wear of nozzles and electrodes.
A defect hose with i.e. air or water leakages will
inevitably cause damage to the torch body and may
create safety hazards for the operator.
Never use a damaged plasmacutting torch!
MAINTENANCE
Daily maintenance:
Check, and if necessary replace, nozzle, electrode
and electrode insulator.
Empty and clean, if necessary, the water separator
filter on the rear of the plasmacutter by pressing the
gasket in the bottom of the glass cap with com-
pressed air connected or by simply unscrewing it
without compressed air connected.
Clean the filter of dirt.
Check both torch body and hose frequently and
regulary for damages such as air, gas or water
leakages, mechanical impact, etc.
ATTENTION!
Never use a torch with damaged torch body or
damaged hose!
Biannual maintenance:
Loosen and remove the plasmacutter side panels.
Check the water level and add destilled water, if
necessary. Add coolant whenever necessary. Use
only monoethylenglycol as coolant.
Coolant cable power < 5µS/cm.
Blow any dust and dirt out of the plasmacutter with
clean and dry compressed air.
Check that the cable connections are secure.
