10 Manual or Automatic Spot Welding Selection Led
By selecting the manual spot welding the led will stay on, by selecting the automatic spot welding the
led will blink.
11 Digital Ammeter
When welding the display views the real welding current. When adjusting the BBT, Slope or Post Gas
values it views respectively BBT, SLP or GAS according to the parameters you are going to adjust.
12 Digital Voltmeter
When welding the display views the real welding current. When adjusting the BBT, Slope or Post Gas
values it views the corresponding values according to the selected menù and viewed by the ammeter.
Note: generator allows to set the wire speed to 11m/min or 22m/min. The selection key is inside the wire
spool compartement. Each time this value is changed, the digital voltmeter views 11 or 22 according to
the selected speed.
13 Torch connection
14 Negative terminal (
connection point for the ground cable: low impedance is suggested for thin welding wires.
15 Negative terminal (
connection point for the ground cable: low impedance is suggested for thick welding wires.

It is possible to spot weld two sheets of up to 0,8mm thickness mild steel by replacing the torch gas nozzle
with a spot welding nozzle (not supplied). Select the desired spot welding function by acting on the Mode
Key (4) and adjust spot time by turning the Regulation knob (6) . Place two sheets one upon another; place
the nozzle on the upper sheet and then press the torch trigger ensuring that the sheets are in contact.
Press the trigger to spot weld the first sheet to the second one. The spot welding will automatically stop
when the adjusted time has passed. For spot welding, the machine must be set at maximum current and
maximum wire speed. It is advisable to use 0,8mm ø wire.

The machine will be set up as for mild steel except for the following changes:
•
100% ARGON as welding protective gas.
•
Ensure that your torch is set up for aluminium welding:
1.
The lenght of the torch cable should not exceed 3m (it is advisable not to use longer torches).
2.
Install a teflon wire liner (follow the instructions for the renewing of the wire liner at paragraph 8).
3.
Ensure that drive rolls are suitable for aluminium wire.
•
Use contact tips that are suitable for aluminium wire and make sure that the diameter of the con-
tact tip hole corresponds to the wire diameter that is going to be used.

•
Connect the ground cable to the proper female outlet on the bottom right-hand corner of the
welder (on some models the ground cable is already connected).
•
Attach the ground clamp to the bare metal to be welded, making sure of good contact;
•
Make sure that the wire-roller groove in the roller corresponds to the diameter of the wire being
used. Refer to paragraph 6.
•
Plug the machine to a suitable outlet.
•
Open the gas valve on the gas cylinder regulator, (turn knob counter-clockwise) and adjust the
flow rate using the regulator knob (turn it counter-clock wise to decrease the gas flow; turn it
clockwise to increase the gas flow). Note: The gas flow may need adjustments in order to obtain
a better welding, this depends on the type and thickness of the metal and on the welding current.
