INSTALLATION
This machine must be used for welding only.
In any case, it is essential to pay special attention to the
chapter on SAFETY PRECAUTIONS.
The symbols next to certain paragraphs indicate points requi-
ring extra attention, practical advice or simple information.
This manual must be kept carefully in a place familiar to
everyone involved in using the machine. It must be consulted
whenever doubts arise and be kept for the entire life-span of
the machine; it will also be used for ordering replacement
parts.
1.1
PLACEMENT

DESCRIPTION OF CONTROLS
2.1 CONTROLS ON THE WIRE FEEDER FRONT PANEL
Q- Wire feed speed control.
This knob adjusts the wire feed speed.
R- Weld function selection switch
This switch selects among the following functions:
Manual welding cycle (2 step):
The machine begins welding when the torch trigger is
pushed and stops welding when the torch trigger is relea-
sed.
Automatic welding cycle (4 step)
The machine begins welding when the torch trigger is
pushed. Once welding has begun, however, the torch trigger
can be released. To stop welding, the torch trigger must again
be pushed and then immediately released. This function is
useful when welding for long periods of time because it helps
reduce operator hand fatigue due to having to keep the torch
trigger constantly pushed during normal manual welding
operations.
S - Trimmer
This trimmer regulates the length of the wire that sticks
out of the torch after welding is finished: "BURN-BACK."
T - Selector switch with automatic spring return.
Use this switch to select the following functions:
Wire feed test.
Holding the switch pressed down in this position feeds out
welding wire from the torch but with the power and gas tur-
ned off.

Gas test.
Use this switch to test gas flow. Holding the switch pressed
down in this position feeds out gas without feeding out wel-
ding wire. On automatic machines, use this switch to fill the
pipes with welding gas to ensure a good welding start.
U- Quick connect torch terminal
The welding torch is attached to this terminal.
V - Status light (yellow color)
When lit, indicates that the thermostat has stopped welder
operation. On machines fitted with a cooling unit this warning
light light up when the cooling unit is off or when the pressu-
re switch indicates a low cooling liquid level.
W - Status light (white color)
This light indicates that the machine is on.
X - Ammeter.
Indicates the welding current.
Y - Voltmeter.
Indicates the welding voltage.
N.B. When welding stops, the ammeter and voltmeter
continue to show the last reading until welding restarts.
Z - Quick-fit hose connectors for connection to water
hoses of water-cooled torches.
Important: These connectors are colour-coded for safety.
Ensure that hose and connector colours match.
P - Spot welding timer knob
This knob adjusts the spot welding time. By pressing the
