"4000" or "5000" and the machines output will be inhibited, after 4 seconds display will clear and the machine is ready to use.
1. Mode Indication
4. Output Demand Control
2. Digital Display
5. 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
Control' or 'Arc Pinch Control' as it regulates the pinch effect of the welding arc.

ing electrodes (e.g. general purpose, celulosic, low hydrogen and iron powder). Turning towards maximum will increase penetration at the expense of in-
creased welding splatter, turning towards minimum will reduce penetration but the arc will be smoother and less fierce.

8. Remote control socket
plugging an external unit into the socket automatically selects remote operation and disables the internal control (4).

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.

- Adjusts the machines output current in CC mode or Voltage in CV mode.
Selects welding mode when there is no remote connection.
- Operates in MMA mode only. This control alters the welding dynamics of the machine to facilitate welding with different types of weld-
- For connection of external remote control, external TIG control unit or wire feed unit. There is no switch for remote operation,
- Operates in MIG mode only. This control alters the response time of the power source and is generally used in short circuit dip transfer
- Main welding power output connector, negative polarity.
- Main welding power output connector, positive polarity.
- Switches the machine on and off.
- Fuse 3.15A slow blow, 32 x 6.3mm ceramic body.
- Protects the auxiliary supply from the remote control socket. Fuse type is 20 x 5mm glass body, 6.3A 'slow blow' rating
