2. DESCRIPTION & SPECIFICATIONS
2.1
DESCRIPTION
Fan cooled AC/DC power supply suitable for TIG and ARC welding applications. Suitable for welding steel,
deoxidated copper, nickel, titanium and aluminium. TIG cycle includes both pre-gas and post-gas regulation
between 0.1 and 10 seconds and current rise and down-slope regulation between 0.1 and 10 seconds. AC
balance fully adjustable between 50% and 90%. LED power read-out with push button programming.
Includes burst HF start device and ‘lift start’ feature which reduces HF emissions. Features 15 user memory
settings and 15 factory settings allowing fast and simple set-up. Includes remote control connector for foot
pedal or hand controller.

PREPARING INVERTER FOR USE
CONNECTION TO MAINS:
3.1
3.1.1 Whilst welding at low power levels is possible on a 13amp supply the Inverter will normally be connected to a 30amp supply in order to TIG weld
at higher power levels and in order to perform ordinary ARC welding. See section 1, item 1.1.10
WELDING CABLE CONNECTION.
3.2
3.2.1 The torch cable is supplied ready assembled but it may be necessary for you to assemble the work clamp cable. Attach the work clamp to one end of the
cable as shown in fig.2. To connect the Dinse Plug as shown in fig.3 first thread the cable through the outer cover of the plug ( see fig.3 - 4 ). Now remove
20mm of insulation sheath from the end of the cable and fold back the copper wire all around the outside of the sheath ( 1 ). Push the cable end into the
copper sleeve ( 2 ) so that the folded back wire makes good contact with the inside of the sleeve. Push the copper sleeve into the brass plug body ( 3 ) and
tighten the large grub screw until the cable is firmly held. Now slide the outer plug cover up the cable and press the brass body into it as shown in fig.3.

TIG CONNECTIONS:
3.2.3
“TIG” TORCH CABLE. Dinse plug at end of the torch cable will be connected to the negative socket ( - ) on lower front panel
3 pin torch plug at end of torch cable will be connected to circular 3 pin socket on the lower front panel.
Black gas pipe with brass fitting at end of torch cable will be screwed to brass fitting on lower front panel. ( see fig.4 item 4 )
WORK CLAMP CABLE. Dinse plug at end of the clamp cable will be connected to the positive socket ( + ) on lower front panel ( see fig.4 item 1 ).
3.2.4 ( * ) Please note that the way the welding cables are connected to the inverter for ordinary ARC welding may be different to the way the cables are
connected for standard TIG welding. Whilst most stick electrodes are connected to the positive terminal certain types need to be connected to the
negative terminal. It is therefore essential that the user refers to the manufacturer’s instructions for the electrodes to ensure that the correct
polarity is selected.
ARC CONNECTIONS:
3.2.5
ELECTRODE HOLDER Plug at the end of electrode cable will normally (* ) be connected to the positive socket ( + ) on the front panel (see fig.4 item 1 ).
WORK CLAMP CABLE. Plug at the end of the clamp cable will normally (* ) be connected to the negative socket ( - ) on the front panel (see fig.4 item 2 ).

REMOTE CONTROL CONNECTOR. For the connection of the optional remote controls shown below.
3.4
REMOTE CONTROLS ( Optional.) Two types of remote control can be connected to the machine via the
14 pin connector situated on the back panel. Press the button in the bottom left hand corner of the front
control panel to select the remote control option. When this option has been selected the knob on the main
control panel becomes inoperative for those functions taken over by the remote control.
3.4.1 Remote control pedal. (Model No. INV/TIG/4) When activated the pedal will control the main welding
current. Also if spot welding has been selected or 2 step TIG welding the first movement of the pedal will
initiate the striking of the arc in place of the torch button.
3.4.2 Remote control with two potentiometers. (Model No. INV/TIG/7) With the machine in remote mode, the
knob furthest away from the cable entry, controls the main welding current. The second knob will control
one other parameter depending on the active welding mode. ( See table below.) The rotation of the second
knob automatically selects the appropriate parameter and brings it up on the display.
3.4.3 Welding mode set up.
