Inverter power supply assembly, welding and cutting power output device and welding and cutting equipment

Abstract

The invention discloses an inverter power supply assembly, a welding and cutting power output device and welding and cutting equipment. The inverter power supply assembly comprises a rectifying and filtering unit for performing rectifying and filtering on inputted power frequency AC power, at least one inverter conversion unit for performing inverter conversion on the power completing rectifying and filtering, at least one step-down rectifying and filtering unit for performing step-down rectifying and filtering on the power completing inverter conversion and a DC power output unit for outputting the DC power completing step-down rectifying and filtering, wherein the DC power output unit comprises a forward DC power output end and a negative DC power output end. Combined online operation can be carried out, the versatility of the equipment is enhanced, and the utilization rate of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of welding and cutting equipment, in particular to an inverter power supply assembly, a welding and cutting power supply output device and welding and cutting equipment. Background technique [0002] The welding and cutting equipment in the prior art is mainly divided according to different application processes: DC manual arc welding equipment, DC argon arc welding equipment (TIG / DC), carbon arc gouging equipment, AC manual arc welding equipment, AC argon arc welding equipment (TIG / AC), cellulose welding equipment, gas shielded welding equipment (MIG / MAG / CO2), submerged arc automatic welding equipment (SAW), plasma cutting equipment (CUT), etc., each category is subdivided according to the current size There are many models, and there are many voltage levels according to different applications. There are hundreds of products in total. [0003] Since welding and cutting products are closely related to the t...

AI Technical Summary

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
