WARNING
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.

5OPERATION
Connect the power source to the electricity mains with a network impedance of 210 ohm
or lower. If the network impedance is higher, there is a risk of flicker in the illuminators.
5.1 Connections and control devices
1 Main power supply switch, 0 / 1 4 Connection for remote control
2 Mains cable 5 Welding cable connector (+)
3 Connection for return cable (--) 6 Control panel (see 6.2)
3 and 5 are used for welding current supply and return cable connection during MMA
welding
5.2 Connection of welding and return cable
The welding power source has two terminals, one plus and one minus pole, for the
connection of the welding and the return cable. Connect the welding cable to the
pole indicated on the package of the electrode to be used.
Connect the return cable to the other terminal. Fit the earth clamp of the return cable
