When the welding machine is switched off, the Over/under voltage alarm signal may
appear for a few seconds.
Following optimal adjustment of the welding machine for a certain type of weld,
proceed as follows:
- Press button C-4 for at least 3 seconds until the screw in Fig. I-13 appears.
- Turn the knob C-5 to choose the number with which you want to save the program
(J1 ÷ 10).
- Press button C-4 for at least 3 seconds until the SAVE icon (
- Press button C-4 for at least 3 seconds until the screw in Fig. I-13 appears.
- Turn the knob C-5 to choose the number used to save the program which you now
intend to use (J1 ÷ 10).
- Press button C-4 to load the chosen program

- Do not put the torch or its cable on hot pieces; this would cause the insulating
materials to melt, making the torch unusable after a very short time.
- Make regular checks on the gas pipe and connector seals.
- Accurately match collet and collet body with the selected electrode diameter in order
to avoid overheating, bad gas diffusion and poor performance.
- At least once a day check the terminal parts of the torch for wear and make sure they
are assembled correctly: nozzle, electrode, electrode-holder clamp, gas diffuser.
- Before using the welding machine, always check the terminal parts of the torch for
wear and make sure they are assembled correctly: nozzle, electrode, electrode-
holder clamp, gas diffuser.
- Make frequent checks on the state of wear of the wire feeder rollers, regularly
remove the metal dust deposited in the feeder area (rollers and wire-guide infeed
and outfeed).
- Inspect the welding machine regularly, with a frequency depending on use and the
dustiness of the environment, and remove the dust deposited on the transformer,

cleaned with a very soft brush or suitable solvents.
- At the same time make sure the electrical connections are tight and check the wiring
for damage to the insulation.
- At the end of these operations re-assemble the panels of the welding machine and
screw the fastening screws right down.
- Never, ever carry out welding operations while the welding machine is open.
- After having carried out maintenance or repairs, restore the connections and wiring
as they were before, making sure they do not come into contact with moving parts or
parts that can reach high temperatures. Tie all the wires as they were before, being
careful to keep the high voltage connections of the primary transformer separate
from the low voltage ones of the secondary transformer.
Use all the original washers and screws when closing the casing.
IN CASE OF UNSATISFACTORY FUNCTIONING, BEFORE SERVICING MACHINE
- Check that when general switch is ON the relative lamp is ON. If this is not the case
then the problem is located on the mains (cables, plugs, outlets, fuses, etc.)
- There is no alarm signalling intervention of the thermostat safeguard, over or
undervoltage or short-circuit.
- Check that the nominal intermittance ratio is correct. In case there is a thermal
protection interruption, wait for the machine to cool down, check that the fan is
working properly.
- Check the mains voltage: if the value is too high or too low the welding machine will
be stopped.
- Check that there is no short-circuit at the output of the machine: if this is the case
eliminate the incovenience.
- Check that all connections of the welding circuit are correct, particularly that the
work clamp is well attached to the workpiece, with no interferring material or surface-
coverings (ie. Paint).
- Protective gas must be of appropriate type and quantity.
