TECHNICAL DESCRIPTION
COD. 6907900030
d) Insert the circular torch connector in the socket provided (ref.37 page 9) .
Welding using the wire feeder TOP 504S-P
a) Connect the earth cable to the positive socket of the generator (ref.35 page 9).
b) Connect the bundle of cables on the front of the generator, inserting the power cable in
the negative socket (ref.38 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
provided.
g) Connect the gas cylinder (Argon) to the special coupling on the rear panel of the
generator using the setting-up kit provided.
h) Insert the plug in a power socket complying with the regulations in force.
i) Switch on the machine, turning the switch on the rear panel to position "1". Switch on also
the cooling unit AWC, if fitted.
When the generator is switched on, all the signals will be displayed for about 2 seconds;
then the displays (ref.5-7 page 9) will show the type of welding selected for 2 seconds.
Regulating the TIG 2t welding parameters
1) Press the SELECT MODE button (ref.29 page 9) until the Tig 2T mode led (ref.33 page
9) lights up.
2) The letters tig will appear on the displays (ref.5-7 page 9) for 2 seconds.
3) Regulating the welding current -The A/wire speed encoder (ref.6 page 9) is used to
regulate the welding current shown on the display on the left (ref.5 page 9).
3a) Regulating the welding current from the wire feeder – The A/wire speed potentiometer
(ref.41 page 10) is used to regulate the welding current following the scale indications or
checking its value on the right-hand display of the generator (ref.5 page 9).
As regards the regulation of the current from the generator or from the wire feeder, the last
regulation made will remain operative.
4) Regulating the slope down – Pressing the SET button (ref.10 page 9) selects the time of
the slope down. The right-hand display (ref.7 page 9) will start to blink, indicating the letters
