1 Euro torch connector.
2 Machine overheating indicator lamp.
3 Power button.
4 Welding tension regulation commutator.
5 Earth cable.
6 Wire feed speed control potentiometer.
7 Welding system selector:
In position press the torch button to start welding, and release to
stop.
In position press the torch button to deliver gas; on release, wire
feed and current are activated; press again to stop wire feed and current and
release to shut off the gas supply.
In position the welder operates in timed mode; press the torch but-
ton to start the welding phase, which stops automatically after the time inter-
val as set on the timer potentiometer.
8 Spot welding time control potentiometer, from 0.3 to 10 seconds (operating
only with selector (Ref. 8 - Fig. 1 page 6) set to position
9 Wire feed motor acceleration time control potentiometer.
10 Control potentiometer to regulate time during which welding power is main-
tained after the relative shutdown signal. In practice, at the end of welding, if
this time is too short, the wire remains stuck in the bath or protrudes too far
from the torch contact tube; otherwise, if the control time is too long, the wire
remains stuck in the torch contact tube, often causing damage to the latter.
11 Quick connectors for ground clamp

6.0 OPTIONAL (USE WITH CORED WIRE)

Your welding machine (If ordered with the optional) can use the special core wire
Ø 0.9 which does not require the use of protection gas. Unlike electrode welding,
this wire does not leave scale and offers greater bead penetration with consider-
ably lower absorption from the line.
Make sure you use proper welding polarity:
