Available in argon arc welding technique, remote control adjustment welding current is Ji Shuai Minus electric currents；Such as impulse welding of some welding procedures, also pulse
Frequency, multiple welding parameters such as dutycycle need regulation, and those skilled in the art are according to the method provided in text, and capable increase is more
Many remote control parameters, the need for adapting to multiple welding parameter regulations.Particular problem to be solved by this invention is as follows：
1) about 1mm or so of the line footpath of the pilot of 6 or more, when that need to move wire-feed motor, welder is dragging
Control line movement wire-feed motor.There are numerous iron blocks differed in size in welding building site, the wire-feed motor dragged often is blocked by body iron block,
And each wire can not be equally long, therefore that most short root pilot is just pulled off.
2) welding building site is all several welders in operation, welder in mobile pilot, often pilot with
Oneself had just been welded or others just welded, and also awfully hot weld seam is mutually touched, and pilot is burnt out.
3) welding building site is often justified with instruments such as sledgehammers to steel plate alignment or school, or during cutting, the bloom fallen all can
Pound disconnected, injure pilot by a crashing object, when flame is cut earnestly, the bloom fallen can also burn out pilot.
4) it is 24V (controlled motor and air valve) to have three wire voltages in this 6 or more pilot, there is three
Wire voltage is 15V or 5V (connecting connection control circuit, single-chip microcomputer etc.).When pilot is smashed or burnt out, the insulation of wire
Layer is damaged, short cut with each other between wire, burns out control panel, carries out damaging expensive IGBT pipes.
Welding engineer and the universal view of welder are:The gas shielded welding machine failure of more than half occurs in this six roots of sensation line
On, therefore, if can reduce or remove this pilot of 6 or more, there is very big practical value in production activity.
There is one in addition to have the advantages that:Gas-shielded welder, its weldingvoltage are moved in either domestic at present or import
Knob, which is adjusted, in wire-feed motor with welding current, but receives arc voltage receives arc current regulation knob on the source of welding current.If because
Receipts arc voltage, receipts arc current regulation knob are also placed in wire-feed motor, then increase by 5 wires again.Therefore welder wants regulation
Receiving arc voltage and receiving arc current to go at the source of welding current, and not being-it is secondary can be transferred to just right, therefore to come and go
Run several times.The present invention can adjust " weldingvoltage ", " welding current ", " receipts arc voltage ", " receipts arc current " 4 parameters, as long as
The program of single-chip microcomputer is slightly changed, more welding parameters are just can adjust.
