See the ACCESSORIES section for available options. 12. Electrode Connection (Positive) - For quick disconnect system using Twist-Mate™ cable plugs 13. Welding Parameter Display - LED’s show which mode or welding parameter is activated for adjustment. • If it is necessary to modify the welding parameters "Item 13": - Wait four seconds after the LED’s on the panel have gone out, the welding current LED will be lit. - Press the SETUP/Parameter push button "Item 4"; every time the push button is pressed, one of the LED’s in the diagram “Item 13” comes on (in clockwise sequence) and the value of the parameter appears on the Digital display "Item 6". Stop at the desired parameter. - Rotate the Output/Parameter Adjust Knob"Item 5" and modify the parameter value. - Press the SETUP/Parameter "Item 4" push button again to pass to another parameter, or wait five seconds and the Weld Current LED will come on again.

To access the Set Up Menu: • Position the ON/OFF switch to OFF “0”. • Depress and hold the Parameter select Push Button. • Position the On/Off switch to on "I" at the back of the machine; the input voltage light "Item 1" (green LED) confirms normal operation. • The SETUP mode is confirmed by a center "0" on the Digital display “Item 6”. - Rotate the Output / Parameter Adjust Knob, the Digital Display shows the numbers corresponding to the parameters in sequence; stop at the desired parameter and push the "Setup/Parameter Push Button". - The number on the Digital display "Item 6" is replaced by the value of the parameter that can be modified through the Output / Parameter adjust knob "Item 5". - With parameter (9) all the modifications made in the SETUP mode are cancelled and the standard values set by Invertec® V205-T AC/DC™ are restored. - To exit the Set Up Menu, return to “0” and press the Setup/Parameter Push Button INDICATOR PARAMETER DEFAULT 0 Exit From Set Up 1 Not Used 2 Pre Flow Time (0 - 25 seconds) 0.5 sec. 3 Arc Force, percent above Peak Current for Stick only (0 - 100%) 30% 4 Hot Start, percent above Peak Current for Stick only (0 - 100%) 80% 5 Setting of AC wave Form 0 = Sinusoidal 1 = Triangular 2 = Square NOTE: This parameter limits maximum weld current, see "OUTPUT LIMITATIONS" section of the manual. 2 (Square) 6 Min.

(Value set for Indicator 6 - Peak Current) NOTE: Peak Current (Max Weld Current) can be limited by input voltage, welding mode, AC TIG waveform and AC TIG frequency. Peak Current 8 Touch Start or H.F. Start in DC TIG (0 = H.F.

(1.0 = min., 5.0 = max.) Note: If the machine does not initiate a welding arc it will repeat the starting sequence with an increased start energy up to this limit. Set this number to a higher setting than the factory default if needed to improve starting of large diameter tungstens electrodes. 2.0 INVERTEC® V205-T AC/DC™ IWHPWfe.
