SECTION 4 — OPERATION
4.1 Operating controls and connections
Description of controls
1. Current control
-
Adjusts the machines output current.
2. Digital Display
-
Indicates welding current in Amps, also gives an indication when the machine is over
temperature.
3. Arc force control
-
Operates in MMA mode only. This control alters the welding dynamics of the ma-
chine to facilitate welding with different types of welding electrodes (e.g. general purpose, celulosic,
low hydrogen and iron powder). Turning towards maximum will increase penetration at the expense of
increased welding splatter, turning towards minimum will reduce penetration but the arc will be
smoother and less fierce.
4. Off/On switch
-
Switches the machine on and off when the main 3 Phase isolation switched is in the
on position. Upon switching on, the display will read “7000” and the machines output will be inhibited,
after 4 seconds the display will clear and the machine is ready to be used.
5. Remote control socket
-
For connection of external remote control or TIG300 external TIG control unit.
There is no switch for remote operation, plugging an external unit into the socket automatically selects
remote operation and disables the internal current control.
6. -ve weld terminal
-
Main welding power output connector, negative polarity
.
7. +ve weld terminal
-
Main welding power output connector, positive polarity.
8. 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.
9. Auxiliary transformer supply fuse
- Fuse 3.15A slow blow, 32 x 6.3mm ceramic body.
10. Main 3P Isolation switch
-
Switches the machine on and off.
11. Mains Input
-
Three phase mains cable.
