Replacement of the welding torch

The units with S mark, designed to operate in highly hazardous ambient are equipped with a protection device which
requires the use of a tool to assemble and disassemble the welding torch.
Unscrew the screws that fasten the protection device to the unit, unscrew the ring nut of the central adapter, remove
the protection device.
Replace the welding torch and follow the previous instructions in reverse direction.
Note
• Do not dent the contact tip, do not bend the welding torch fitting pins.

THIS SECTION IS RESERVED TO SKILLED PERSONNEL ONLY.
5.3.1

Replacing the welding torch body /cable (only for CP70C MAR)

Unscrew the 6 screws V Fig.3 and remove the LH grip.
•
• With reference to Fig.4, lift the welding torch body T with cable and disconnect connector A (push-button) and
connector B (pilot arc) making sure that the push-button components (see Fig. 5) remain in the original position.
• Remove heat-shrinking hose C and unscrew nut D (wrench #13) by keeping fitting E (wrench #11) fastened.
• Replace the welding torch body/cable.
Screw in fittings D and E according to the arrow direction - Fig. 6.
•
Tighten fittings, introduce the heat-shrinking hose C and use a small heat source to warm it up.
•
• Connect connector B, introduce the welding torch body into the grip seat and then connect connector A by
introducing it inside the grip as shown in figure 4.
• Reposition LH grip making sure not to flatten any wire between the grip rims.
• Screw in the 6 screws V again.
Making reference to Fig. 2 , parts subject to wear are as follows: electrode A, swirl ring B,
nozzle C and nozzle protection E. These should be replaced after unscrewing the nozzle
holder D.
WARNING:
Electrode A must be replaced when it shows an approx 1.2 mm deep crater at the centre.
Nozzle C is to be replaced when its central hole is damaged or enlarged as compared
to a new one. Delayed replacements of electrode and nozzle cause overheating , which
can reduce swirl ring B life. After these replacements, check that the nozzle holder D is
accurately tightened.
WARNING: screw the nozzle holder D onto the welding torch body only when electrode
A, swirl ring B and nozzle C are assembled. If these elements are not assembled the
equipment operation is jeopardized as well as the operator's safety.
