Problems solved by technology

[0003] Since welding and cutting products are closely related to the type, thickness, and process of the processed raw materials, many products occupy their own subdivision fields. Due to technical limitations, except for large currents to small currents, there are additional functions to no additional functions. Forward substitution of functions (DC argon arc welding equipment is replaced by DC manual arc welding equipment), reverse substitution cannot be performed, and there is no universality at all
When the production project changes to face different processes and materials, the user can only re-purchase equipment
However, the originally purchased equipment can only be idle or seldom used, resulting in a lot of waste of resources. Due to climate, improper storage and other reasons, various problems often occur when the equipment needs to be used. There is no specific technology and size standard, and maintenance is extremely difficult, which urgently needs to be solved
