1. SAFETY PRECAUTIONS - READ BEFORE USING

The use of welding equipment can cause
injury to the operator. The reading and understand-
ing of the safety standards mentioned below is com-
pulsory prior to connecting, preparing, using or
transporting welding equipment.

1.1 INSTALLATION OF EQUIPMENT

1. Installation and maintenance of equipment
must be performed in compliance with local
safety standards.
2. Frequently inspect the welder plug,
receptacle and wiring. If damaged, replace
immediately with approved electrical connec-
tions and adequately sized wiring.
3. Connect the welding ground as near as possi-
ble to the operating area.
4. Do not pass welding equipment cables through
or near lifting chains, crane cables or any elec-
trical lines.
5. If earth grounding of the workpiece is required,
ground it directly with a separate cable.
6. Do not touch the electrode if you are in contact
with the work, ground or another electrode from
a different welding machine.
7. Use only well-maintained equipment. Repair or
replace damaged parts immediately. Maintain
welding equipment according to owner's manu-
al.
8. Never use welding equipment near water. Do not
spray water or other liquids on the welding equipment.
9. Avoid direct contact between wet garments and
metal parts that are electrically charged.
10.Always wear gloves and rubber-soled shoes
when working in wet areas or standing on metal
surfaces.
11.Always turn off welding equipment that is not
being used. Do not leave welding equipment
unattended.
Significant DC voltage exists after removal of
input power or inverters.
• Always discharge input capacitors before touch-
ing any parts. Service work should be complet-
ed by qualified personnel only.

1.2 PERSONAL PROTECTION

1. Welding operations produce radiation, noise,
heat and noxious fumes. Suitable safety pre-
cautions must be taken to minimize the risk.
2. Wear fire resistant work gloves, long
sleeve shirts, pants, safety shoes, cap and
welding helmet to protect the skin from radia-
tion and metal sparks.
3. Always wear ear protection.
4. Always wear eye protection with side shields.
5. Position a fire resistant screen around the weld-
ing area to protect bystanders from radiation,
sparks and slag.
