How to troubleshoot the welding machine

Date 06/05/2019

Any device during the use of the incident is inevitable. In addition to understanding the principles of machine operation, practical experience will help you know how to fix problems with your work equipment.

Trouble shooting a DC welding machine

No.	Incident	Reason	Handling
1	Motor reversal welding machine	Motor induced three-phase wrong wiring	One of the three three-phase fuses is cut off
2	After turning on the machine, the motor speed is slow, there is a scream	One of the three three-phase fuses is cut off	Replace the fuse or bend the stator windings
3	The welding machine is too hot	Overload, Roto coils of the machine short circuit, commutator power is short or not clean	Stop the machine to fix the above problems if any
4	The charcoal brush has a spark	Electric contactors and contactors do not work well, charcoal grills are trapped	Electric contactors and contactors do not work well, charcoal grills are trapped

Solving AC Welding machine problems

No.	Incident	Reason	Handling
1	Transformer overheat	Overload or transformer winding has been short-circuited	Reduced welding current to handle problems if any
2	The wiring is overheated	The wiring harness is loose	Tighten the screw
3	The process of welding electric current able to be large or small	The object with the contact cable is not good contact. The vibration of the regulator vibration by vibration of the machine	Check the contact between the weld and the cable, adjust the current.
4	Check the contact between the weld and the cable, adjust the current.	Less brakes or spring of liquid iron core. The core of the iron core is worn out. Primary or secondary windings shorted	Solve troubles listed
5	The casing of the machine is electric	nsulator between coil and outer layer is open. Winding with iron core is leaking electricity	Handle the insulating system of the machine
