Energy-saving wireless remote control arc welding apparatus

Abstract

The invention relates to an energy saving wireless remote control electric arc welder at least comprising a detection unit, a main control unit and a remote control unit, wherein the detection unit is used for detecting feedback sampling voltage signals; the main control unit is used for judging a current state according to the feedback sampling voltage signals detected by the detection unit; when the welder is not in a welding state, protection voltage is outputted, and a blower is controlled to stop running at the same time; when the welder is in the welding state, the protection voltage is converted into normal welding voltage, and the blower is controlled to run; the remote control unit is connected to the output end of the control unit; when the welder is not in the welding state, the remote control unit is used for regulating welding parameters (such as welding current); and when the welder is in the welding state, the remote control unit goes out of service. The energy saving wireless remote control electric arc welder achieves the effect of energy saving, realizes the function of protection against electric shock, and has the function as a wireless remote controller.

Description

technical field [0001] The invention relates to a welding machine, in particular to an inverter energy-saving wireless remote control arc welding machine. Background technique [0002] The no-load voltage of ordinary electrode arc welding machines is generally above 60V (the IGBT inverter-controlled welding machine is about 60-80V, and the no-load voltage of the thyristor AC-DC dual-purpose machine is higher). In the harsh working environment of the shipbuilding industry, welding workers are in danger of electric shock at any time when the working environment is relatively humid or the body sweats a lot, endangering personal safety, and in the non-welding state, the no-load output voltage of the welding machine remains Keep it above 60, and the fan keeps running, which not only wastes a lot of electric energy, but also has a great impact on the service life of the fan. [0003] In addition, most welding machines do not have the function of wireless remote control, so that i...

[0002] The no-load voltage of ordinary electrode arc welding machines is generally above 60V (the IGBT inverter-controlled welding machine is about 60-80V, and the no-load voltage of the thyristor AC-DC dual-purpose machine is higher).

[0003] In addition, most welding machines do not have the function of wireless remote control, so that if welding operators need to adjust welding parameters during on-site construction, they must return from the welding site to the welding machine for operation, which consumes a lot of man-hours and is also difficult for workers. adds some complexity
