AUTOMATIC WELDING MACHINE TROUBLESHOOTING Analysis and troubleshooting of common faults 1 Welding must be carried out in a dry environment at a humidity of 90 or less 2 The temperature of the operating environment should be between 10 C and 40 C 3 Avoid outdoor welding if there is no protection from sunlight and rain Welding all the time should be dry do not put it on the wet ground or in puddles 4 Avoid welding in dusty places or places with corrosive chemical gas 5 Welding in a protective environment should be carried out in places where there is no strong air movement Faults Solution Overheat LED is on 1 Check arc welding current and welding time See manual and work as required 2 Check the condition of the fan rotation during welding If the fan does not work check that the power of the fan is 230V if power is ok check fan if the power is out of order check the power cable No reaction when pressing the blow pipe button 1 Check whether the power LED and digital meters are lit 2 Check the contact of the blow pipe button connection of the welding blow pipe 3 Check the wire feeder connection and the 1 Check the contact of the power cable connected to workpiece 2 Check that the quick release plug is connected to correct quick release socket 3 Check the wire feeder connection 4 Check for damage in the welding blow pipe 5 Failure of the RC 94 PK 94 control board inside machine When you press the blow pipe button for gas 1 Check the wire feeder for blockage or damage supply there is an output current but the wire 2 Check the contact tip of the welding blow pipe feeder docs not feed the wire blockage or damage 3 Failure of wire fee RC 93 PK 93 the The wire feeder feeds the wire when the blow pipe button is pressed to supply gas but there is no output current and the protection LED does not light up the the for You can weld by pressing the blow pipe buttons 1 Verify that the wire feeder control cable is working but the voltage is not adjustable No load voltage 2 Failure of the control board inside the machine too high Arc welding current unstable 1 Check for proper pressure on the press lever of the wire feeder 2 Check if the driving roller matches the size of wire used 3 Check for wear on the contact tip of the welding blow pipe Replace and tighten if necessary 4 Check the quality of the welding wire 5 Check that the blow pipe cable is not too bent 6 Check if the quick release plug is loosely inserted 7
