Description

Technical Field

[0001] The invention relates to a wireless remote adjustment mechanism of a welding machine, belonging to the field of Internet and welding equipment, in particular to the application of Internet technology on welding equipment. Background Art

[0002] A widely used gas shielded welding machine includes a welding power supply and a wire feeder. One output end of the welding voltage adjustment potentiometer Wh in the wire feeder control box is the Ku point, and the welding voltage set value at the Ku point is a negative voltage. One output end of the welding current adjustment potentiometer Wi is the Ki point, and the welding current set value at the Ki point is a positive voltage. The Ku point and Ki converge into a point K, so the voltage at the K point can be positive or negative. The purpose of this arrangement is to reduce the number of control wires. One wire can transmit two given values ​​of welding current and welding voltage, which are distinguished by their positive or negative values.

[0003] The two signals of the gun switch button Ng and the manual wire feeding button Nh in the wire feeder control box are also transmitted by one wire. The endpoint where the two signals are connected is L. When neither the gun switch button Ng nor the manual wire feeding button Nh is pressed, the voltage at point L is 15 volts. When the gun switch button Ng is pressed, point L is 0 volts, which controls the start and stop of welding. When welding is started, an arc is generated, and when welding is stopped, the arc is extinguished. When the manual wire feeding button Nh is pressed, point L is 7.5 volts, and only wire is fed at this time, and no arc is generated. The purpose of this arrangement is to reduce the number of control wires. One wire can transmit the two signals of the gun switch and the manual wire feeding, and the voltage values ​​of the two are used to distinguish them.

[0004] There are two welding cables connected between the welding power supply and the wire feeder. One end of one welding cable is connected to the positive terminal of the welding power supply, and the other end of this welding cable is connected to the head of the wire feeder. One end of another welding cable is connected to the negative terminal of the welding power supply, and the other end of this welding cable is connected to the weldment.

[0005] The control signal between the welding machine power supply and the wire feeder is transmitted by a six-core control cable or a seven-core control cable. The first wire is the analog (welding voltage and welding current) signal line. One end of the analog signal line is connected to point K, and the other end of the analog signal line is connected to pin 7 of the control board CN3 in the welding power supply. The second wire is the switch signal line. One end of the switch signal line is connected to point L in the welding wire feeder mechanism box. When the gun switch is pressed, point L changes from positive 15 volts to 0 volts. When the manual wire feeding button is pressed, the voltage at point L changes from positive 15 volts to about 7.5 volts. The other end of the switch signal line is connected to pin 6 of the control board CN3 in the welding power supply. The third wire is the ground wire, and the other end of the ground wire is connected to pin 8 of the control board CN3.

[0006] There is a remote control box at the wire feeder, which contains a wireless remote control transmitter YF and a power module. There is a wireless remote control receiver YS at the welding machine power supply.

[0007] The situation at the welding site is complicated. There are cars and tractors transporting parts and welding materials on the site. Cars and tractors will crush and break the six-core control cable or the seven-core control cable. Iron blocks will fall off on the site and break the six-core control cable or the seven-core control cable. The welder will drag the six-core control cable or the seven-core control cable for dozens of meters. Some part of the six-core control cable or the seven-core control cable will touch the red weldment that has not been cooled yet, and the contact part between the six-core control cable or the seven-core control cable and the red weldment that has not been cooled yet will be burned, causing a short circuit between the internal connections of the six-core control cable or the seven-core control cable, short-circuiting the 24-volt line with the 0-volt line, the 15-volt line or the 7.5-volt line in the six-core control cable or the seven-core control cable, and burning components such as the integrated block connected to these wires.
