WARNING OVERLOAD PROTECTION SPARE PARTS Use only manufacturer-recommended spare parts. Check that the power source supplying the Welder carries the Other spare parts could cause equipment mal- correct voltage and is safety-protected. The power switch must open all the function. The use of non-original spare parts will also result in the war- ranty provisions becoming null and void, releasing the manufacturer power supply circuits.
WARNING DAMAGED GAS CYLINDERS WALL AND FLOOR PROTECTION NEVER use damaged or faulty cylinders. The walls and flooring surrounding the welding CYLINDER RELOCATION environment must be shielded using non-flammable materials. This not only reduces the risk of fire but also avoids damage to the wal- NEVER lift a gas cylinder by holding the regulator.

ALARMS/TROUBLESHOOTING 7.1 ERROR MESSAGES Here are led signal errors: DESCRIZIONE Short-circuit error “Err. S.C.”. This error can occurs only when the machine is welding in MMA. Changing from MIG modality to MMA modality if the electrode makes contact with the work- piece or with another metal surface, then the short-circuit error appears which prevents inverter starting.
Page 25
ALARMS/TROUBLESHOOTING Undervoltage error “Err. LInE”. This error occurs when the machine measures undervolatge condition. Error solving: The machine will start again automatically to function when the voltage grow up to an uncri- tical value. Thermal overload error “Err. tHr”. This error occurs when the machine is in thermal overload due to an excessive overheat- ing.
CARE AND MAINTENANCE DAILY MAINTENANCE • Supply cable and its discharge traction • Welding current conductors (verify their locked and tight position) • Gas tubes and their commutation devices (electric valve) • Gas cylinder fixing elements • Use, alert, protection and position devices (functioning control) •...
