2.0 INSTALLATION

2.1 CONNECTING THE UNIT TO THE ELECTRIC CIR-
CUIT
This equipment tolerates a variation of +/- 10% in
supply voltage. Ensure that the connector is well-
equipped with fuses capable of supporting the
intensity indicated in the table of specifications for
the unit.
Fumes and gas produced by welding
can be dangerous if inhaled for prolonged peri-
ods of time. Observe the following advice:
2.2

SELECTING A LOCATION

Fumes and gas produced by welding
can be dangerous if inhaled for prolonged peri-
ods of time. Observe the following advice:
1. Consult the table of specifications for electri-
cal energy requirements.
2. The operator should have free access to con-
trol and regulatory equipment and to all con-
nections.
3. Do not position the unit is small or enclosed
areas. Ventilation of the area is extremely
important. Ensure that air admission points
are not obstructed and that there is no risk of
obstruction during operation, in order to elimi-
nate possible risk of overheating and damage
to the unit.
4. Avoid dirty and dusty locations where dust
could be drawn into the inside of the unit by
the ventilation system.
5. The equipment (including the cables) must
not constitute an obstacle to the free move-
ment or work activities of other people.
6. Position the unit on a stable surface to prevent
it from falling or being knocked over.
7. Bear in mind the possibility of the unit falling
when placing it high above floor level.
INSTALLATION
2.3 CHANGING THE POLARITY
EXTINGUISH THE UNIT BEFORE ALTERING
CONNECTIONS
USE WITH NON-GAS WIRE (check polarity with
the wire manufacturer)
1. Connect the earth cable to the positive termi-
nal located inside the unit.
2. Connect the welding cable (Ref 1 – Fig.1) to
the negative terminal located inside the unit.
USING WITH WIRE AND INSERT GAS FOR
WELDING SOFT STEEL.
1. Connect the earth cable to the negative termi-
nal located inside the unit.
2. Connect the welding cableto the negative ter-
minal located inside the unit.
3. Install a tube between the pressure reducing
valve of the gas canister and the input connec-
tor positioned behind the unit.

FITTING THE TORCH

EXTINGUISH THE UNIT BEFORE PROCEEDING
TO CONNECTIONS
Before connecting the torch, ensure that the reel
installed corresponds to the diameter of the wire
to be used. Also check that the dimensions of the
slot in the drive roller, the contact tube and the
guiding tube correspond. Check that the guiding
tube does not touch the rollers.
To install the welding torch, follow the instruc-
tions below:
