Abstract

The invention relates to a welder control circuit system which is mainly characterized in that a display operation unit and a signal output module are connected with a welder control unit; data information detected by an output voltage detection module, a temperature detection module, a thermistor and an input voltage detection module is transmitting to the welder control unit through lines; a wireless communication module is also connected onto the welder control unit, and used for sending and receiving communication data; a fan is connected to the output end of a cooling fan control unit through a line; a power-on relay and a power-on relay control unit are electrically connected with each other; and after an input power source passes through an input switch, an input end capacitor, a wave filter and an output end capacitor in sequence, two poles of the output end of the input power source are electrically connected with the ground through a first grounded capacitor and a second grounded capacitor correspondingly. The welder control circuit system provided by the invention has the advantages that the voltage application scope is wide, the display of state parameters is visual, and the safety is high.

Description

technical field [0001] The invention relates to the field of welding machine control equipment, in particular to a welding machine control circuit system. Background technique [0002] With the development of industry, electric welding machine has been widely used as an indispensable welding equipment in industrial production. MMA welding refers to a welding method in which the electrode in the electrode holder acts as the welding electrode, the arc burns between the electrode and the workpiece, and the electrode as the welding electrode shortens as the welding progresses. The electrode holder must be constantly moved towards the workpiece so that the distance between the electrode and the molten weld remains constant. MMA welding can be used in almost any condition, so it is a fairly common method in the welding industry. The IGBT inverter DC welding machine is a new type of arc welding power source. Its good electrical performance and remarkable energy-saving effect have...
