I've trying to dial in my welder.I troef it on 50ms pre weld 500ms wait 50ms weldI immediatly blew a hole in the nickel plates.Also i troef to washer at 50, 500, 500 and they are gone now too Is this because it has nothing but wood under it or do i need the limit the current?
I want to buy Spot welder control board with TFT display to fix Sunkko S788H, I have no experience with Arduino at all, just want to utilize the complete and tested board.Does the board fit on the Sunkko 788 front panel, do I need to remove the broken Sunkko PCB.Do the SCR Q1B and Q2B need additional heat sink or not.
Ok.I tried 50, 450, 50ms and pressed about 2kg on the pins. And. Wam. Pins are shorter now and black. And did you now the inside of an 18650 is blue? I did remove the the transformer (bumblebee) shunts btw and did not put them back
Can i modify the software to use 0-50ms in steps of 1.Normal spotwelders weld in 1-30msI used the continous weld en tabbed the button real quickly and it welded perfect
I did not pressed the button. I striked it. Like a Ninja It's definitly shorter then the 50msI've hooked up the ttl and started ide software. Imported the spotweld7.1.inoI get fault: missing streaming.h and alot of other librarysMost of them i have found. except for the TFT_Ili9341Isn't there a complete package available?And i don;'t know what lines to change to get 1ms increments in all weld and pause times
That will make the current go up.I have looked at alot of welders. They usually work in the 1-30ms range.What parameters do i have to change?I compiled a sketch but it says:De schets gebruikt 24830 bytes (76%) programma-opslagruimte. Maximum is 32256 bytes.Globale variabelen gebruiken 965 bytes (47%) van het dynamisch geheugen. Resteren 1083 bytes voor lokale variabelen. Maximum is 2048 bytes.I already found the line const int step_ms = 50;
