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.
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 ' A rc Control' or ' A rc Pinch Control' as it regulates the pinch effect of the welding arc.
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 automatically selects remote operation
8. +ve weld terminal
Main welding power output connector, positive polarity.
9. -ve weld terminal
Main welding power output connector, negative polarity.
10. Main 3P Isolation switch
Switches the machine on and off.
11. Mains Input
Three phase mains cable.
12. Auxiliary transformer supply fuse
Fuse 3.15A slow blow, 32 x 6.3mm ceramic body.
13. Remote supply fuse
Protects the auxiliary supply from the remote control socket. Fuse type is 20 x 5mm glass body, 6.3A 'slow blow' rating
14. Main supply fuse to the cooling unit (Only fitted to cooling unit version)
Fuse 3.15A slow blow, 32 x 6.3mm ceramic body.
15. Auxiliary Cooling unit (only fitted to cooling unit version)
Protects the auxiliary supply to the cooling unit. Fuse type is 20 x 5mm glass body, 2A 'slow blow' rating.
