ENGLISH
Regulating the electrode mode welding parameters
1) Press the SELECT MODE button (ref.29 page 9) until the Electrode mode led (ref.34
pag.9) lights up.
2) The letters arc will appear on the display (ref.5 page 9) for 2 seconds.
3) The weld enable led lights up (ref.2 page 9)
4) 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 right (ref.5 page 9)
4a) Regulating the welding current from the wire feeder – The A/wire speed
potentiometer (ref.41 page 10) is used to regulate the welding following the scale
indications or checking its value on the left-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.
5) The display on the left (ref.7 page 9) indicates the generator output voltage.
6) Regulating the ARC-FORCE function - Pressing the SET button (ref.10 page 9) selects
the ARC FORCE led function (ref.14 page 9). The display on the left (ref.7 page 9) will
start to blink indicting the letters AF; with the V/SET encoder (ref.8 page 9) you can
regulate the value from 0 to +50% of the set current.
7) The Hot-Start value is already automatically regulated to have an optimum start.
Perform welding
During welding, the value of the real welding current is shown on the display (ref.5 page
9) ; the value of the real welding voltage is shown on the display (ref.7 page 9).
At the end of welding, both displays will keep for a few seconds the real current and
voltage values obtained during welding.
- TIG 2 TIME WELDING
Preparing the machine
TIG 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:
Welding using only the generator
a) Connect the earth cable to the positive socket of the generator (ref.35 page 9).
b) Connect the Tig torch to the negative socket of the generator (ref.38 page 9).
c) Connect the gas pipe of the torch to the connector on the front (ref.36 page 9) .
