OPERATION

B-6

 

 

 

Bi-Level Current – (If Enabled from the Setup Menu) Depressing an arc start switch and releasing will initiate the arc to current level A1. Depressing and releasing the arc Start switch again will toggle to cur- rent level A2. Each depressing and releasing of the switch will toggle between A1 and A2. Depressing and holding the switch in will initiate the down slope to the finish current level and finally releasing the trigger will extinguish the arc.

Spot Timer - (If Enabled from the Setup Menu) Selecting this trigger mode will enable a spot timer para- meter setting to be displayed as a welding parameter. Once the arc is establish the machine will weld for the time period set by the spot timer para- meter setting. The machine will follow the functionality of two-step in that start current, up-slope, down-slope and finish current can all be adjusted.

STICK TRIGGER MODES

Local - In this mode the machine ignores any remote that is plugged. The machine will weld at the preset value set at the panel of the machine.

Remote - Allows the amperage to be set with a remote potentiometer.

C. TIG PULSE MODES

Pulse On - Turns on pulse welding in TIG mode. Changes the sequence diagram to Pulse TIG and allows the adjustment of the following added parameters:

Pulse Frequency

% Peak Time

Background Current

Pulse Off - Turns off pulse welding in

TIG.

D, E, & F. Memory Operation – Pressing and releas- ing the memory location (D) button will scroll through memory locations 1 through 10. When a memory is recalled or saved the memory location display will change to reversed text indicating that the current memory parameters are active.

Normal Display

Reversed Display

(Unselected)

(Selected)

Saving to Memory

Press and hold Memory Save Button (E) until the memory location display indicator (D) changes to a reverse text indicating that the current parameters are the ones in the actively selected memory.

Recalling from Memory

Press and hold the memory recall button (F) until the memory location display indicator (D) changes to reversed text indicating that the stored parame- ters are actively recalled.

When memory parameters are actively selected, the display indicator will remain reversed until a welding parameter is changed with the encoder knob or until the memory location button is pressed to scroll to a different memory location

Local/Remote Operation – The Invertec® V311-T AC/DC, when in TIG mode, will automatically sense when the machine has a remote device plugged into the 6 pin MS-typeconnector-like a remote pendant or a foot amptrol. If a remote device is plugged in, the machine will automatically function in remote mode. If no device is plugged in, the machine will function in local mode.

In remote mode, the operation of the machine is slightly different depending on whether the remote device is a foot amptrol or a remote pendant. To let the machine know what type of device is plugged in, the operator must select the appropriate device from the trigger mode button. (See Trigger mode descrip- tions above for details on the difference. In stick mode the second button on the control panel selects local or remote operation manually. This is required so that the user does not need to detach a foot amp- trol to use the machine in STICK mode.
