Function and instruction

Parameter setting:

A.First spot weldingbetween

1. adjustable range 1-99 AC cycle (for safety reasons, the board defaults to a maximum value of 20, if the need is greater than 20, please see the maximum value in the back, limit a section, change the maximum limit can be changed).

Two "time"1"When the indicator light is lit, the code switch is pressed, the digital tube starts flashing, the coding switch is turned to the required value, and the coding switch is pressed again to save and withdraw.


Two.First spot welding current


1. adjustable range25%-99%Adjust the SCR turn-on time to the percentage of cycle time(the board defaults to a maximum value of 99. If you need other values, see the maximum value at the back, limit one section and change the maximum limit yourself.).


Two "current1"When the indicator light is lit, the code switch is pressed, the digital tube starts flashing, the coding switch is turned to the required value, and the coding switch is pressed again to save and withdraw.


Three.The interval between the first and second spot welding


1. adjustable range1-99AC half cycle, that is, the value is multiplied by 10 milliseconds(the board defaults to a maximum value of 25. If you need more than 25, please see the maximum value at the back, limit one section and change the maximum limit yourself.).


2. when the "interval" light is lit, press the code switch, the digital tube flashes, turn the code switch to the required value, press the code switch again, save and exit.


Four.Second spot welding time


1. adjustable range0-99AC cycle(for safety reasons, the board defaults to a maximum value of 20. If you need more than 20, please see the maximum value at the back, one section, and you can change the maximum limit yourself.)


2.This time is set as0When operating, it operates in a single pulse state.


3. "time"2"When the indicator light is lit, the code switch is pressed, the digital tube starts flashing, the coding switch is turned to the required value, and the coding switch is pressed again to save and withdraw.


Five.Second spot welding current


1. adjustable range25%-99%Adjust the SCR turn-on time to the percentage of cycle time(the board defaults to a maximum value of 99. If you need other values, see the maximum value at the back, limit one section and change the maximum limit yourself.).


2. "current2"When the indicator light is lit, the code switch is pressed, the digital tube starts flashing, the coding switch is turned to the required value, and the coding switch is pressed again to save and withdraw.


Six.Parameter storage and transfer


1., the machine can store five commonly used parameter settings, storage and retrieval methods are as follows:


2. press the code switch when the "welding parameter" light is lit, and display the number of the current parameter.


3. press the code switch again, enter the load and storage parameter selection, turn the code switch turns to show"Ld","SAIndicate that the subsequent operation is loaded or stored, and if you need to load parameters, display"LdPress the code switch, and display if you want to store parameters"SAPress the code switch when pressing.


4. connect the bar, display the number of the current parameter at this time, turn the code switch, the screen is from the0-4The changes represent five items of parameters, select the number of entries to be stored, and press the encoding switch again to realize loading or storage.


5.. This machine loads automatically when it is turned on0Parameter under the item number, so you can store the most commonly used parameters in the entry0.


Maximum value limit:


Usually handmade by the spot welding transformer, power, wire diameter, number of turns are not the same, caused by parameters of large discreteness, controller to adapt to a variety of parameters of transformer, the adjustable range of the large, most likely because of improper cause damage to the battery (I had for the tone of the long spot welding,so thatBatteryIf the shell is learned) on the maximum value of each parameter, so the limit is very necessary, this machine has the maximum limit function parameter setting method, as follows:


1. Rotary encoding switch, make "welding parameters" indicator light, then press the encoding switch does not let go, about 5 seconds into the upper limit function, the "time 1" lights, at the same time the digital display the current value of spot welding time limit 1.


2. Turn the switch "1 encoding time" and "current" interval "1", "2" and "2 current" flashing in turn, and display their maximum value, select the desired setting parameters, short press the switch after encoding digital tube flashing at the same time, the rotary encoding switch to change the limit to the desired again after a short press numerical encoding switch, the display stops blinking, defining the current parameter value is set to complete.


3. The limit value set, need to save to take effect by turning the switch to the "encoding welding parameters" lights, digital display "SA", then press the encoding switch, save and exit, as do storage, all settings are invalid, the control panel is still according to the original limit operation.


Installation:

The installation size figure (with controller isolation column and installation screw) pay attention to insulation.



Matters needing attention

  • The area on the board with "live danger" has a 220 voltage, including a heat sink, so this part is not allowed to touch when energized

  • The test machine, the welding time should be small to major, cannot come to the large welding burn, will put the welding needle burning noodles, generally 18650 with 0.15 nickel plate tune to 5-10, here is the number of digital frequency AC, 5-10 frequency is about 100-200 ms the transformer and power, the first level solder wire diameter, distance, is the value of experience, this machine can store five parameters, so we can take the best parameters stored for days after the call

  • On the transformer, the general use of microwave transformers, secondary with 25-35 square millimeters of copper around the three or four turns to meet the requirements, if the use of two transformers, the secondary side of the circle or two laps after the series ( Pay attention to the phase), for only spot welding 18650 battery, a transformer is enough, even if the aluminum coil is enough (I used for the aluminum wire oven transformer, 25 square copper wire around the three, welding 18650 battery effect well).

  • Board power supply must be AC, such as through the direct current will show E0 and buzzer alarm, such as replacement of power supply transformer, please pay attention to the AC voltage.

  • Because of the previous Taiwanese friends to buy the board, in order to adapt to Taiwan's power supply done 50HZ, 60HZ adaptive, board power will detect the mains frequency, about two seconds after the show "50" or "60", this value represents the frequency The


  • Physical picture:

  • The photo is still used before the single-pulse control panel, in addition to the display board from the three LED increased to six, RC capacitive absorption circuit resistance has been adjusted, the filter capacitor rose from 25V to 35V, the other did not change, Should not produce misunderstanding it


 

Often friends asked: you control this is wide? Phase shift Here to do some simple instructions: the general homemade spot welding are using off-the-shelf high-power transformers, the primary fixed and the secondary winding from around the difficulty of winding can not be like a finished spot welding machine by changing the tap Adjust the spot welding current, so the general control panel to use multi-phase trigger mode to adjust the output current size, spot welding work has two basic parameters, one is the welding time, one is the welding current, control time is more convenient, Industrial timer drive solid-state relay program, but the need to tap on the transformer to adjust the output current, while the timer can not be synchronized with the exchange of zero, under certain circumstances there will be positive and negative half of the cycle error, the production cost is high The cost of the emergence of 555 with a class of time as a timer to control the spot length of the same time using the RC phase-shift circuit to do SCR control and then control the output current of the program, which is a simple and effective way , But the timing accuracy is poor, generally with the dial shows the welding time, conduction angle, not intuitive, the current method is more perfect mining AC zero crossing collected microcontroller, to achieve the phase shift delay trigger thyristor object, and precise control of MCU spot time while interacting with a computer interface to facilitate the operation.
On the single and double pulse: only at the set time to set the current to complete a welding called a single pulse, due to some special circumstances, such as weldment itself stains or welding enameled wire due to contact resistance problems may exist welding Bad, the first pulse is used to burn stains or patent leather (of course, before welding must be crushed or otherwise conductive), the second pulse is the true sense of the welding, this method is generally used in the electrical plant for enameled wire and Commutator between the welding, for double pulse welding, must be done twice the welding time, current and the two welding intervals are adjustable, need to carefully adjust the parameters in order to achieve good welding results.

This machine is a single pulse to do zero detection, delay trigger thyristor conduction to adjust the welding current of the double pulse controller
