14. ORDINARY MACHINE MAINTENANCE
Every three months periodically remove dust from the suction nozzle using compressed air.
Always direct the air from the inside towards the outside of the machine to avoid blowing dirt
inside the welder. When carrying out this operation, always make sure the machine is not con-
nected to the power supply.
15. REPLACING THE WIREGUIDE SHEATH OF THE TORCH
When replacing the wire guide sheath follow these instructions carefully:
• Torch side: remove the gas pipe (A).
• Unscrew the wire feed tip (B)
• Connector side (C): turn the terminal nut (D, E) and hold the end of the sheath with a pair
of pliers and pull (F).
• Fully extract the sheath (G).
• Insert the new sheath and push it all the way down to the bottom (H).
• Fasten the wire feeder tip (B) to the torch.
• When replacement has been carried out, reattach the gas nozzle.
When carrying out this operation make sure you do not lose the O-RING (rubber gasket
that prevents any eventual gas leaks.
