Problems solved by technology

After leaving the factory, the customer can no longer calibrate the zero point parameters of the remote control box. If there is a deviation, please contact the quality inspection personnel for re-inspection and calibration or directly replace the analog remote control box.
However, the resistance characteristics of the analog remote control box are dispersed. When a fault occurs in actual operation and needs to be replaced, the resistance characteristics of the analog remote control box used by the customer are not exactly the same as those used in quality inspection. After the customer uses the analog remote control box purchased by himself, the scale of the analog remote control box will also be inconsistent with the display on the panel of the welding machine
At the same time, through manual calibration parameters, the calibration is complicated, time-consuming, and not accurate enough

Embodiment 1

[0030] An automatic calibration system of an analog remote control box is installed in the internal function system of a welding power source. The control panel of the welding power source is provided with an internal function key F key, an encoder knob and a display interface, and the control panel is connected to the internal function system through a circuit. The automatic calibration system of the analog remote control box includes ON mode and OFF mode. The ON mode is the automatic calibration operation mode of the analog remote control box, including the output value adjustment module, the value comparison module, the fixed value flashing module and the cycle detection module; the OFF mode is the end of the automatic calibration mode, including the module of automatic saving of calibration parameters, the module of automatic shutdown of the calibration system and the module of entering normal welding mode. The automatic calibration method of the analog remote control box u...

Embodiment 2

[0038] An automatic calibration system for an analog remote control box, the system is installed in the internal function system of a welding power source, the control panel of the welding power source or the analog remote control box and the peripheral equipment connected to the welding machine are provided with a button M key, and the M key is directly connected through a circuit Automatic calibration system. The automatic calibration system of the analog remote control box includes ON mode and OFF mode.

Abstract

The invention discloses an automatic calibration system for an analog remote control box and an automatic calibration method for an analog remote control box. The automatic calibration system of the analog remote control box is installed in the internal function of the welding power source. The specific operation method includes: Step 1, align the pointer to the middle scale, and press and hold the F key to enter the internal function of the welding machine; Step 2, select the automatic calibration system and switch to ON mode, start calibration; step 3, stop beating when the displayed value is consistent with the value on the middle scale, and the value starts to flash; step 4, after the value starts to flash, turn all the pointers to the minimum scale, and start automatic calibration again; step 5 , when the displayed value is consistent with the minimum scale value, it stops beating, and the value blinks. After the blinking, the automatic calibration system jumps to OFF mode, the calibration parameters are saved, the system exits, and the welding machine enters the normal welding mode. The invention can realize the automatic calibration of the analog remote control box, which is beneficial to improving the precision of the analog remote control box and improving the welding effect.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to an automatic calibration system for an analog remote control box and an operation method for the automatic calibration of the analog remote control box. Background technique [0002] During welding, due to the different distances between the welding power source and the welding site, the required current and voltage cannot be adjusted at any time through the control panel on the welding power source, so the analog remote control box plays an important role in the on-site welding process. The remote control box can remotely adjust the current and voltage during welding, but since the current and voltage values ​​output by the welding machine are completely determined by the values ​​displayed on the control panel, the welder is far away from the welding power source and cannot accurately see the values ​​displayed on the control panel. The scale value pointed by the pointer on the...
