Power supply input rectifying and filter circuit after being used for outside input current carried out rectification and filtering, are assistant SCM and drive chip power supply;
Assistant SCM is used to receive the welding current that the user imports, and converts this welding current to pulse signal output;
Drive chip, be connected, be used for the driving transformer circuit, and the pulse signal of described assistant SCM output is loaded on the input of transformer with described assistant SCM;
Transformer circuit, its input is connected with the driving chip, is used for described pulse signal is fed back to the light-coupled isolation device by cable;
The light-coupled isolation device is used for feeding back to control module after the pulse signal optocoupler isolation with feedback.
The utility model provides the inverse transformation electric arc welder remote control circuit, described remote control circuit is used for not regulating welding parameter under the welded condition, and this welding parameter is sent to described control module, described control module is controlled the output bonding power of described power model according to this welding parameter.The workman need not to turn back to welding machine from the scene of welding and comes to operate like this, reduces the complexity of workman's operation effectively.
Description of drawings

The specific embodiment
A kind of inverse transformation electric arc welder remote control circuit, comprise control module and the remote control circuit that is connected with described control module communication, described remote control circuit is used for not regulating welding parameter under the welded condition, and this welding parameter is sent to described control module, described control module outputs control signals to described power model after receiving this welding parameter.Wherein, described control module is a single-chip microcomputer.
Wherein, the theory diagram of described remote control circuit as shown in Figure 1, Fig. 2 is the remote control circuit design example, it specifically comprises:
Power supply input rectifying and filter circuit after being used for outside input current carried out rectification and filtering, are assistant SCM and drive chip power supply;
Assistant SCM is used to receive the welding current that the user imports, and converts this welding current to pulse signal output, and the operating voltage of described assistant SCM is+5V;
Drive chip, be connected with described assistant SCM, be used for the driving transformer circuit, and the pulse signal of described assistant SCM output is loaded on the input of transformer, the operating voltage of described driving chip is+15V;
Transformer circuit, its input is connected with the driving chip, is used for described pulse signal is fed back to the light-coupled isolation device by cable;
The light-coupled isolation device, the pulse signal of feedback feeds back to single-chip microcomputer after light-coupled isolation.
The course of work of remote control circuit in whole inverse transformation electric arc welder remote control circuit is as follows:
Under welded condition not, welding machine output floating voltage is about 13 ± 2V, in case welding rod contact workpiece, be connected remote control circuit on the output both positive and negative polarity this moment, welding machine output floating voltage is converted to 60～80V, and remote control circuit is started working, and regulates required welding current by assistant SCM, electric current to be welded can carry out normal welding operation after regulating and finishing.
For guaranteeing safety, remote control circuit can not be operated in welding process, and after last time welding finished, remote control circuit can be operated once more according to above-mentioned steps.
Wherein, described assistant SCM can adopt identical single-chip microcomputer with described control module, can make communication each other compatible more like this, has simplified the design of circuit.
