Sd; with the V/SET encoder (ref.8 page 9) you can regulate the value from 0.1 to 12.5
seconds.
To view the set value at any time, briefly press the SET button.
5) Regulating the post-gas time - Pressing the PG button (ref.11 page 9) selects the post
-gas time. The right-hand display (ref.7 page 9) will start to blink, indicating the letters

Procedure for TIG 2 TIME welding with LIFT start
Starting welding:
1) Regulate the desired welding parameters
2) Bring the tip of the electrode (tungsten) into contact with the piece to be welded.
3) Press the torch button: after 0.5 seconds of PRE-GAS, lift the torch from the side so
as to move slightly away from the piece to be welded and start the welding process.
End of welding:
1) Release the torch button: the current gradually falls with the time set by means of the
SET button (ref.10 page 9); the arc goes out and then there will be the POST-GAS time
set by means of the PG button (ref.11 page 9).
- MIG 2 TIME WELDING
Preparing the machine
MIG welding may be carried out in various ways, depending on the specific requirements
of the operator. In this case you must proceed as follows to prepare the machine:
a) Connect the earth cable to the negative socket on the generator (ref.38 page 9).
b) Connect the bundle of cables on the front of the generator, inserting the power cable
in the positive socket (ref.35 page 9) , the gas pipe on the respective coupling (ref.36
page 9), the circular connector in the socket provided (ref.37 page 9) .
c) If the generator is equipped with an AWC (cooling unit), and if you want to use a torch
equipped with pipes for carrying the cooling fluid, the connectors of these pipes must be
connected to the BLUE and RED quick couplings .
d) Connect the bundle of cables on the rear panel of the wire feeder, inserting the power
cable in the Din socket (ref.51 page 11), the gas pipe on the respective coupling (ref.48
page 11) , the circular connector in the socket provided (ref.49 page 11) and eventually
the water pipes on the BLUE and RED quick couplings (ref.52,53 page 11).
e) Connect the torch to the EURO socket on the wire feeder (ref.43 page 10).
f) Position the gas cylinder (Argon) in the rear cylinder carrier and anchor it with the chain
