Installation; Connecting The Equipment To The Main Supply; Selecting A Location; Connection And Preparation Of Equipment For Stick-Electrode Welding - Air Liquide ALW-M170500180 Owner's Manual

4.1 CONNECTING THE EQUIPMENT TO THE
MAIN SUPPLY
The equipment is shipped without a plug installed.
It works within a wide range of input voltage from
90 VAC to 270 VAC. The electronic circuitry in this
unit automatically links the power source to the pri-
mary voltage being applied. The recommended
plug for 115 VAC input power is 5P-15 and for 230
VAC input power is 6P-50. Check to ensure that the
power outlet is equipped with a fuse that is capable
of carrying the amps indicated on the data plate of
this unit.
Deactivation of the power source during
welding could cause serious damage to the
equipment.

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 equipment,
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 extreme-
ly important. Make sure that the louvers 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.

EQUIPMENT FOR STICK-ELECTRODE
WELDING
Connect all welding accessories carefully to pre-
vent power loss. Carefully follow safety precau-
tions described in section 1.
T U R N O F F W E L D E R B E F O R E M A K I N G
CONNECTIONS.
1. Connect the ground cable to the negative recep-
tacle and locate the ground clamp near the welding
zone.
2. Connect the electrode cable to the positive
receptacle and fit the selected welding electrode
into the electrode holder.
3. Use the above connection for welding elec-
trodes that use DCEP (Reverse Polarity) welding
current. Reverse the connection for welding elec-
trodes that use DCEN (Straight Polarity) welding
current.
EQUIPMENT FOR TIG WELDING
Connect all welding accessories carefully to
avoid power loss or leakage of dangerous gases.
Carefully follow the safety standards described
in section 1.
T U R N O F F W E L D E R B E F O R E M A K I N G
CONNECTIONS.
1. Connect the TIG torch power cable to the nega-
tive receptacle on the unit.
2. Connect the TIG torch gas hose to the gas outlet
on the regulator located on the compressed gas
cylinder.
3. Install the correct tungsten and nozzle for the
welding application on the TIG torch.
