How to maintain the small current of welding machine?

1. The low current of welding machine is generally caused by the long wire of the handle. In general, the length of the welding machine handle line should be kept between three meters and five meters. Once it exceeds five meters, the current will drop. At this time, the cross-sectional area of the handle wire should be increased to change the current intensity, or the length of the handle wire should be shortened to a suitable range and the length of the incoming wire should be lengthened.

2. If the problem can't be solved, the current of the welding machine is small, which may be caused by the loose connection position of the tapping switch of the welding machine. At this time, it is necessary to carefully check whether the external wiring at the tap changer position is loose, and if it is loose, it should be tightened. If there is no response, a new tap changer should be replaced.

How to use and maintain welding machine correctly.

1. When using electric welding machine, the construction must be carried out in strict accordance with the correct usage specifications. After the construction is completed, it must also be managed and stored in strict accordance with the correct management norms to avoid problems during construction and storage.

2. When the welder is not used, it must be cleaned regularly. When cleaning, use dry compressed air to blow, so that the dust inside the welding machine can be blown clean. In the process of handling the welding machine, never make violent movements, and you must unplug the power plug to move the welding machine. In case of failure during construction, the power supply of the welding machine must be cut off in time to avoid accidents.
