operation. The thermal switch is placed on the main transformer central coil.
3 – Machine under voltage – When lighted indicates that machine is under voltage.
4 – Digital display – Shows the selected parameter value (Mecapulse times and wire speed adjustment). During welding:
- the digital display indicates welding current value
- when the button is rotated the digital display shows the wire motor speed m/min, after this adjustment automatically
returns to welding current value.
5 – V+ Mecapulse – When selected allow adjust upper speed time.
6 - V- Mecapulse – When selected allow adjust lower speed time.
7 – I2 – Welding current – When selected welding current is showed on the digital display.
8 – Wire speed – When selected allows adjust, by means of the adjusting button, the wire speed between 0 and 18 m/min.
This parameter is continuous active; with machine running, select this function with key button 9 to adjust wire speed.
9 – Selector key button – Selects to adjust Mecapulse times and wire speed adjustment and to display welding current
reading.
