2. 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-).

4. 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).

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
5. Control' or 'Arc Pinch Control' as it regulates the pinch effect of the welding arc. Slope control
6. Arc force control - Operates in MMA mode only. This control alters the welding dynamics of the machine to facilitate welding with different types of weld-

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.
7. Remote control socket

8. Inductance control
plugging an external unit into the socket automatically selects remote operation and disables the internal control (4).
9. -ve weld terminal
8. 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
