How to make a spot welding from microwave transformer

I want to show you my experience to make a spot welding from Microware Transformer.

//Code upload to Arduino
int button = 8;
int out = 2;

  Serial.begin(9600);
  pinMode(out, OUTPUT);
  pinMode(button, INPUT);

  Serial.println(value);
  

  int voltage;
  voltage = map(value,0,1023,0,2000);
  Serial.println(voltage);
  int buttonStatus = digitalRead(button);
  Serial.println(buttonStatus);
  Serial.println();
  delay(100);
  if ( buttonStatus == 1 ) {
    if ( voltage > 0 && voltage <= 100 ) {
      delay_0_0_5();
