The invention provides a three-purpose welder logic control circuit. The three-purpose welder logic control circuit comprises a gas shielded arc welding function module, an argon arc welding function module and a manual welding function module, wherein the gas shielded arc welding function module, the argon arc welding function module and the manual welding function module share the same logic control circuit; the gas shielded arc welding function module is used for selecting and implementing a gas shielded arc welding function; the argon arc welding function module is used for selecting and implementing an argon arc welding function; the manual welding function module is used for selecting and implementing a manual welding function and shielding the gas shielded arc welding function. The three-purpose welder logic control circuit simplifies a control circuit of a three-purpose welder, and has the excellent anti-interference capacity while the functions are ensured.
Description
technical field [0001] The invention relates to an electric welding machine, in particular to a logic control circuit for a three-purpose welding machine. Background technique [0002] With the development of inverter welding machine technology, it is increasingly difficult for single-function welding machines, such as manual arc welding machines, argon arc welding machines and gas shielded welding machines, to win the favor of consumers in the market. The three-function welding machine combined with manual welding, argon arc welding and gas shielded welding is becoming more and more prominent in the civilian welding machine market. The combination of logical functions among the three welding functions has become a complex project. The first thing to solve is the distinction between the three functions, including manual welding, argon arc welding and gas shielded welding, and then carry out the various welding functions. The setting involves gun switch signal, wire feed ena...
