Heat Stepper with computerized curve, requires only two values to be entered. Consistent Welder Output is assured with the Automatic Voltage Compensation (AVC). This option maintains welder output at +/- 2% with an input line voltage variation of +/- 12%. Weld Heat "ON-THE-FLY" Change uses a "+" and "-" button on the keypad to increase or decrease the program heat by 1% each push. Change limits are customer set. Changing the heat setting this way does not change the permanent program heat setting. Electronic Counter automatically displays welds made or completed parts welded. Water Saver Circuit to drive 115 volt solenoid valve, conserve water and protect operator during tip replacement.
