Preparing the machine
Proceed as described for MIG 2 TIME welding
Regulating theMIG spot welding parameters: manual regulation
1) Press the SELECT MODE button (ref.29 page 9) until the SPOT mode led PUN
(ref.30 page 9) lights up.
2) The letters PUn will appear on the displays (ref.5-7 page 9) for 2 seconds.
3) Regulating the wire speed – proceed as described for MIG 2 TIME welding
4) Regulating the welding voltage – proceed as described for MIG 2 TIME welding
5) Regulating the spot welding time tP. - Pressing in sequence the SET button
(ref.10 page 9) you can select the spot welding time tP function led (ref.17 page 9).
The right-hand display (ref.7 page 9) will start to blink, indicating the letters tP; with
the V/SET encoder (ref.8 page 9) you can regulate the value from 00.1 to 10
seconds.
To view the set value at any time, briefly press the SET button.
6) Regulating the ARC TRIM Electronic Inductance. – Press in sequence the SET
button (ref.10 page 9) and proceed as described for MIG 2 TIME welding
7) Regulating the BURN BACK time - proceed as described for MIG 2 TIME welding
8) Regulating the post-gas time - proceed as described for MIG 2 TIME welding
9) Gas PURGE function - proceed as described for MIG 2 TIME welding
10) INCH wire advance function - proceed as described for MIG 2 TIME welding
MIG SPOT WELDING procedure: manual regulation
Starting welding:
1) Hold down the gas PURGE button (ref.11 page 9) for a few seconds to purge the
gas.
2) Press the INCH button (ref.13 page 9) for manual advance of the wire, so as to
make the wire run through the torch until it is just protruding from the nozzle.
3) Set the welding parameters.
4) Perform welding: press and hold down the torch button (the green Led (ref.2 page
9) lights up); for a short time (0.5 seconds) the gas will come out (pre-gas), then the
wire will start to come out and the arc will be lit.
5) It is possible to vary the characteristic of the arc using the ARC TRIM function. It
is recommended to start welding with the value set at 0. If any splashes occur during
welding, increase the ARC TRIM value; instead, if the wire tends to stick and burns
