Troubleshooting
Before contacting service center for technical assistance perform the following checks:
• ensure the welding current regulated by potentiometer corresponds the diameter and type of the
used electrode;
• power indicator (On) shall not lit when there is power failure (check cables, outputs, fumes etc.);
• yellow indicator shows overheating, short circuit, too low or too high voltage;
• check voltage of the power line. Machine will not work if the voltage is too low or too high. Machine
will start automatically only if voltage returns back to normal level;
• ensure that there is no short circuit on the output of the machine. Otherwise eliminate the defect;
• all connections of the welding circuit must be operational, and functional terminal must be securely
fixed to the work piece to be welded.
