In Synergic Mode use the Mode Key - 1 - to select the correct Synergic curve according to the alloy type

and the used wire diameter.

9.0

In Manual Mode (SYN OFF) this unit can work with self-shielding,

flux core wire. As default unit is ready for Gas Welding, so for Wel-

ding without Gas, Welding Current Polarity has to be changed ac-

cording to the following steps.

WARNING: Electric Shock can kill! Always turn the power

OFF and unplug the power cord from the power source before

changing polarity.

•

Connect the earth cable to the positive output terminal on the front

of the unit.

•

Connect the torch terminal ring to the negative mounting post on the

Voltage Change Board located just over the wire feeding motor on

the inside of the unit.

For Gas Welding remember to ripristinate the default polarity setting:

•

Connect the earth cable to the Negative output terminal on the front

of the unit.

•

Connect the torch terminal ring to the Positive mounting post on the Voltage Change Board located

just over the wire feeding motor on the inside of the unit.

Note: remove diffuser when welding without gas to avoid excessive heating of the torch.

Mode Key -

Press the Mode Key till the MIG/MAG Welding

Screen is viewed on the display.

MIG/MAG Function Setup Key -

Press the Setup Key - 3.1 - in MIG/MAG Mode to

access the parameters' setup screen.

Use the Right Regulation Knob

"Synergy OFF" Mode.

Use the Mode Key - 1 - to go back to the MIG/

MAG main screen. Refer to paragraph 7 for the

other parameters' setting.

Right Regulation Knob -

Use the Right Regulation Knob to adjust the welding voltage.

Material Key -

Use the Material Key to adjust the electronic inductance value.

This setting allows to stabilize the arc by adapting it to the type of material and to the ope-

rator's hand.

Low Inductance = Cold Arc, more spatters, reactive arc

High Inductance = Hot Arc, few spatters, unreactive arc

Left Regulation Knob -

Use the Left Regulation Knob to adjust the wire speed.
