4.1 Description of controls
Front View
1. Mode Indication - LEDs to display welding mode (MIG 400 power source only the MIG LED will function).
Panel layout
2. Rotary encoder
- Adjusts the machines functional parameters and user settings, as well as output current in CC mode or Voltage in CV mode (when not controlled remotely).

the machines output will be inhibited, after 4 seconds display will clear and the machine is ready to use.

Off/On switch
4. Digital Display - Indicates welding current in Amps, welding voltage in Volts. The display also gives an indication when the machine is over temperature (-OT -) , or the optional
cooling unit is turned off (-CU-).

5. Inductance control - Operates in MIG mode only. This control alters the response time of the power source and is generally used in short circuit dip transfer welding. Too little
inductance will result in excessive spatter and too much inductance will not allow the welding current to rise fast enough causing the electrode to stub into the base metal.
5. Inductance control
6. Slope control - Operates in MIG mode only. This control alters the output voltage(V) to output current(I) relationship. This control is sometimes know as 'Arc
6. Slope control
Pinch Control' as it regulates the pinch effect of the welding arc.
7. Remote control socket
7. Remote control socket - For connection of external remote control or wire feed unit. There is no switch for remote operation, plugging an external unit into the socket automati-
cally selects remote operation
8. -ve weld terminal
8. +ve weld terminal - Main welding power output connector, positive polarity.
9. +ve weld terminal
9. -ve weld terminal
- Main welding power output connector, negative polarity.
10. Main 3P Isolation switch
10. Main 3P Isolation switch
- Switches the machine on and off.
11. Mains Input - Three phase mains cable.
