P-Tronic 40P - 70 - 100
In certain applications the contact cutting may be required even with currents over the 40A (ex. high
cutting speed on thin metal sheet or on high ticks where a high cutting precision is required).
In those applications , use the spare parts described in the picture:
pos (9) Currents until 50A Tip diam 1,0
cod
Z0145AA
pos (9) Currents until 70A Tip diam 1,1
cod
Z0146AA
pos (9) Currents over 70A Tip diam 1,2
cod
Z0147AA
pos 11 Use Shield cup body

pos 12 Use Shield cup hand

Z0140AA
NOTE: the spare parts are the same even if a straight automatic torch is used
- 8 -
8.1 Standard Stand Off
This is the typical and most commun cutting type; you can adjust the current from a minimum
of 20A to a maximum of 70A. Once the cutting is terminated the arc strikes off and it can be
reactivated pressing the torch trigger once again. Use always the spacer (8) unless you have
particular precision needs as described in “GRATING” paragraph.
Electrode (3) and gas diffuser (4) remain always the same for all applications and currents:
pos (3) Electrode
cod. Z0048AA
pos (4) Gas diffuser
cod. Z0049AA
pos (7) Outer nozzle
cod. Z0055AA
Chose tip size (5) for contact cutting without the spager (8) the current set must be
lower than 40A. Pos (5) contact tip 0,9 cod: Z0050AA
Choose the tip size (6) according to the used current. Consider that the cutting width
is about twice as much the tip diameter:
currents until 50A Tip diam 1,0 mm
cod. Z0051AA
currents from 50 up to 70A Tip diam 1,2mm
cod. Z0053AA
8.2 Grating
In GRATING cut position, the minimum current stays at 20A and the maximum at 40A.
When the arc moves from the solid to the grating open area, the generator re-
turns automatically in pilot arc condition and the cutting arc starts again touch-
ing a new solid area. We recommand the stand off spacer to improuve the
spare parts life and the use of the tip (6)
Currents until 30A
cod: Z0087AA (diam 0,8)
Currents until 40A
cod: Z0051AA (diam 1,0)
Consider that the cutting width is about twice as much the tip diameter. This
position (grating) is suggested even for precision cuttings, on thin metal sheets
(thickness less than 6 mm): use a tip for contact cuttig and spare parts as
shown in position 5 of the picture.
Take off the spacer (8) and use the Tip position (5)
cod.
Z0050AA (diam 0,9)
8.3 Gouging
In GOUGING position you can remove material with a high efficiency; the cur-
rent regulation from 20A up to 70A enables the increasing of the groove’s deep.
The torch spare parts remains the same for each current regulation:
