POT value incriments by a value

would possible increase vale of pot steps of value 50.

code: [select]

const int relay = 4;
const int weldbtn = 2;
const int pot = a0;
int potvalue = 0;
const int preweldbtn_ms = 10;
const int pause_ms = 500;
const int weld_step = 50;
int value = 0;
int buttonstate = 0;

void setup()
{
  pinmode (relay, output);
  pinmode (weldbtn, input_pullup);
  serial.begin(9600);
}

void loop()
{
  buttonstate = digitalread(weldbtn);
  if (buttonstate == low)
{
  potvalue = analogread(pot);
  value = map(potvalue,0,1023,50,450);
  digitalwrite(relay,high);
  delay(preweldbtn_ms);
  serial.print("relay on: ");
  serial.println(preweldbtn_ms);
 
  digitalwrite(relay,low);
  delay(pause_ms);
  serial.print("relay off: ");
  serial.println(pause_ms);

  digitalwrite(relay,high);
  delay(value);
  serial.print("relay on: ");
  serial.println(value);
  serial.println("");
      }
      else
      {
      digitalwrite(relay,low);
      }
}

from above code wish increase value of value steps of 50. such every value pot value shoult increase 50, 150, 200, 250.....450

how multiplication operator?

(what happened 100?)
