1 SAFETY

Users of welding equipment have the ultimate responsibility for ensuring that anyone who works on
or near the equipment observes all the relevant safety precautions. Safety precautions must meet
the requirements that apply to this type of welding equipment. The following recommendations
should be observed in addition to the standard regulations that apply to the workplace.

All work must be carried out by trained personnel well--acquainted with the operation of the welding
equipment. Incorrect operation of the equipment may lead to hazardous situations which can result
in injury to the operator and damage to the equipment.

1. Anyone who uses the welding equipment must be familiar with:

S its operation
S location of emergency stops
S its function
S relevant safety precautions
S welding

2. The operator must ensure that:

S no unauthorised person is stationed within the working area of the equipment when it is

started up.

S no--one is unprotected when the arc is struck

3. The workplace must:

S be suitable for the purpose
S be free from draughts

4. Personal safety equipment

S Always wear recommended personal safety equipment, such as safety glasses, flame--proof

clothing, safety gloves.

S Do not wear loose--fitting items, such as scarves, bracelets, rings, etc., which could become

trapped or cause burns.

5. General precautions

S Make sure the return cable is connected securely.
S Work on high voltage equipment may only be carried out by a qualified electrician.
S Appropriate fire extinquishing equipment must be clearly marked and close at hand.
S Lubrication and maintenance must not be carried out on the equipment during operation.

WARNING

READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.

ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU­TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.

ELECTRIC SHOCK -- Can kill

S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.

FUMES AND GASES -- Can be dangerous to health

S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing zone

and the general area.

ARC RAYS -- Can injure eyes and burn skin.

S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

S Protect bystanders with suitable screens or curtains.

FIRE HAZARD

S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

NOISE -- Excessive noise can damage hearing

S Protect your ears. Use earmuffs or other hearing protection.
S Warn bystanders of the risk.

MALFUNCTION -- Call for expert assistance in the event of malfunction.

PROTECT YOURSELF AND OTHERS!

WARNING!

Read and understand the instruction manual
before installing or operating.

Do not use the power source for thawing frozen pipes.

WARNING!

This product is solely intended for arc welding.

Do not dispose of electrical equipment together with normal waste!

In observance of European Directive 2002/96/EC on Waste Electrical and Electronic
Equipment and its implementation in accordance with national law, electrical equipment
