Before connecting, preparing or using
equipment, read Section 1: Safety Precautions.
4.1 CONNECTING THE EQUIPMENT TO THE
MAIN SUPPLY
The equipment works within a ±10% input voltage.
Check that the power outlet is equipped with a fuse
that is capable of carrying the amperes indicated
on the units dataplate.
Deactivation of the power source during
welding could cause serious damage to the equip-
ment.
4.2 SELECTING A LOCATION
Special installation may be required
where gasoline or volatile liquids are present
(See NEC Article 511 or CEC Section 20). Do not
move or operate this equipment where it could
tip over. When selecting a location for this equip-
ment, ensure that the following guidelines are
followed.
1. Use data plate to determine input power
requirements.
2. The operator must have unobstructed access
to all controls and equipment connections.
3. Do not position equipment in small, closed
places. Ventilation of the power source is
extremely important. Make sure that the lou-
vers on the side panels are not obstructed and
that there is no risk of obstruction during
operation.
4. Avoid areas where dust or other objects could
be sucked into the system.
5. Equipment must not obstruct corridors or
work activities of other personnel.
6. Position the power source securely to avoid
falling or overturning.
7. Understand the risk of falling equipment situ-
ated in overhead positions.
4.3 CONNECTION AND PREPARATION OF
EQUIPMENT FOR STICK ELECTRODE
WELDING
Connect all welding accessories carefully to pre-
vent power loss. Carefully follow safety precau-
tions described in Section 1.

CONNECTIONS.
DC Mode
1. Connect the ground cable to the negative
receptacle and locate the ground clamp near
the welding zone.
2. Connect the electrode cable to the positive
receptacle and fit the selected welding elec-
trode into the electrode holder.
3. Use the above connection for welding elec-
trodes that use DCEP (Reverse Polarity) weld-
ing current. Reverse the connection for weld-
ing electrodes that use DCEN (Straight
Polarity) welding current.
AC Mode
1. Connect the ground cable and the electrode
cable to the AC receptacles.
2. Fit the selected welding electrode into the
electrode holder.
