N.B. When welding stops, the ammeter and voltmeter
continue to show the last reading until welding restarts.
D - Led (yellow color)
This led lights on when:
- that the thermostat has stopped welder operation.
- When the side door is open
- on machines fitted with a cooling unit, that the pressure swit-
ch indicates a low cooling liquid level or that the cooling unit is
off.
E - Led (green color)
This led signals that the machine is on.
F - Knob
This knob regulates the length of the wire that sticks
out of the torch after welding is finished: "BURN-BACK."
G- 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 released.
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 trig-
ger 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.
H- Wire feed speed control.
This knob adjusts the wire feed speed.
I - 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.
4.2 CONTROLS ON THE WIRE FEEDER REAR PANEL
L - Gas hose fitting for extension gas hoses.
M - 6-pin socket connector for 6-pin plug connector
N - Socket for extension power supply plug.
O - Quick-fit hose connectors for connection to extension
water hoses.
Important: These connectors are colour-coded for safety.
Ensure that hose and connector colours match.
5 START-UP
Assemble the welding torch on the central adapter (A).
Make sure that the wire diameter corresponds to the one
indicated on the wire feed roller, and load the wire reel. Make
sure that the welding wire passes through the groove in the
roller.
Before connecting the generator power cable, make sure
that the supply voltage corresponds to that of the welding
machine, and that the earth socket functions properly.
Turn on the generator.
Remove the tapered gas nozzle.
Unscrew the contact tip.
Press the torch trigger and release it only when the welding
wire comes out.
Welding wire can cause puncture wounds.
Never aim the torch at parts of the body when loading the
welding wire.
Screw the contact tip back on, making sure that the hole dia-
meter corresponds to the wire used.
Slide the tapered gas welding nozzle back on.
6 ACCESSORIES
Art. 131 AMMETER + VOLTMETER
Plug the 3 connections coming out from the intermediate
panel of the wire feeder to the Ammeter/Voltmeter and fix it
to the front panel, by means of the screws supplied, as
shown in the drawing.
