5.1 - MIG / MAG WELDING – SYNERGY OFF
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 welding without
gas, welding current polarity has to be changed according 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.
For welding without gas, change the
power polarity as following:
■
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.
(Information sticker located
just over the wire feeding
motor on the inside of the unit).
For gas welding remember to reinitiate the default polarity setting as
following:
■
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.
NOTE: REMOVE DIFFUSER WHEN WELDING WITHOUT GAS TO
AVOID EXCESSIVE HEATING OF THE TORCH.

Use the right setting knob to adjust the welding voltage.
Material Key
4
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 operator’s hand.
Low inductance = Cold arc, more spatters.
High inductance = Hot arc, few spatters.
Left Setting Knob

Use the left setting knob to adjust the wire
speed.
