AUTOMATIC WELDING MACHINE INSTALLATION AND OPERATION Connecting the input cable 1 Check with the multimeter power supply whether the voltage is within acceptable limits 2 This welding machine has a power cable Connect the power cable to the rated input power source For safety reasons grounding is required 3 Die cable must be firmly plugged into a socket MMA adjustment 1 This welding machine has two high speed plugs Insert the quick release plugs into the quick release sockets on the front of the machine and tighten them to ensure good contact Otherwise plugs and sockets will bum when working long and high working current 2 Insert the cable plug with the electrode arm into the socket on the front of the machine and tighten clockwise Insert the cable plug with the workpiece clip into the socket on the front of the machine and tighten clockwise 3 Usually in MMA mode DCEP positive DC electrode and DCEN negative DC electrode connections are used DCEP connect the clip of the electrode to the output connector and the workpiece clip to the output connector DCEN connect the electrode clip to the output connector and the workpiece clip to the output connector Operators can choose the connection mode depending on the workpiece and electrode application requirements If you select the wrong connection mode will occur phenomena such as unstable arc excessive spray electrode adhesion To resolve the problem change the connection by swapping the high speed plugs 4 When operating if power is supplied through an extension cord choose a large section extension cable to reduce voltage drop Mode of operation 1 After installing according to the above method and turning on the air supply power on the rear panel the unit starts the power led lights up and the fan is running 2 Switch the MMA MIG switch to the MMA position and adjust the arc welding current with the current control knob according to the workpiece thickness 3 In general depending on the diameter of the electrode the arc welding current should be as follows 2 5 55 80 A 3 2 70 120 A 4 0 130 160 A 5 0 180 210A MIG adjustment 1 Check with the multimeter power supply whether the voltage is within acceptable limits 2 Connect the welding blow pipe to the adapter connector on the front panel of the semiautomatic welding machine Insert the cable plug with the workpiece clip into the socket on the front panel of the machine and tighten it clockwise 3 Flip the cover of the semiautomatic welding machine Install the wire reel on the reel table Turn the reel by hand To prevent unwinding of the wire it should be turned with little effort 4 Release the hold down roller clip on the feeder Insert the wire through the feeder receiver tube into the spiral guide of the adapter Make sure that the wire gets into the groove of the driving roller fix it with a hold down roller The driving roller has two grooves 0 8 mm and 1 0 mm Check that the groove size matches the diameter of the wire used 5 Remove the nozzle from the blow pipe unscrew the copper current collector tip 6 Connect the plug of the semiautomatic welding machine power cord to 220V 50Hz If the socket is without a grounding pin ground the semiautomatic welding machine case with a separate cable to the grounding pin on the back of the machine Then turn the switch on at the rear panel to the on position 7 By briefly pressing the MODE SELECTION button switch set the semiautomatic welding machine to the desired 2T or 4T mode only the corresponding led will be lit 8 Connect the wire feeder with the gas hose to the gas bottle feed regulator 5
