TIG mode

The remote will default to the 6-pin amphenol if a remote control is connected to the 6-pin amphenol and one of the 14-pin amphenols. If a remote is not connected to the 6-pin amphenol then the remote will default to the 14-pin amphenols if a remote is connected to one of the 14-pin amphe- nols.

If a remote control is connected to any of the amphenols the WELD TERMINAL control will default to REMOTE. If there are not any remote control devices attached the WELD TERMINAL control will default to ON.

CC-Stick modes

The remote will default to only the 6-pin amphenol if a remote is connected to it.

The WELD TERMINAL control will default to ON with or without a remote connected.

Types of Remote OUTPUT CONTROL

The Invertec V350-Pro’s Output Control can be controlled by either a potentiometer connected between 77 & 75 with the wiper connected to 76 or a 0V to 10V DC supply connected between 76 & 75. (76 needs to be positive)

14-Pin Amphenol lead 75 is pin G, lead 76 is pin F and lead 77 is pin E.

6-Pin Amphenol lead 75 is pin C, lead 76 is pin B and lead 77 is pin A.

Potentiometer Control

The total resistance should be between 2000 ohms (2K) and 10,000 ohms (10K)

The machine output will be at minimum when lead 76 (wiper) is at the end of the potentiometer that is connected to 75. The machine’s output will increase as the wiper of the potentiometer is moved to the end that is connected to 77. (Note: In TIG mode, moving the lead 76 (wiper) to lead 77 would produce the current that has been set by the Invertec V350-Pro’s front panel Output Control.)

Remotes of this type offered by Lincoln Electric are the K857, K812 and K870.

Voltage Control

The supply should be an isolated supply. (Not ref- erenced to earth ground, any auxiliary power from the Invertec V350-Pro or the welding output) The supply should be capable of supplying at least 20mA.

0 volts supplied to 76 will set the Invertec V350-Pro to minimum output for the mode that has been selected while 10 volts supplied to 76 will set the Invertec V350-Pro to the maximum output for the mode. (Note: In TIG mode, 10 volts supplied to lead 76 would produce the current that has been

Types of Remote WELD TERMINAL Control

The Invertec V350-Pro’s Weld Terminals can be controlled from each of the amphenol connectors. The circuit has a nominal OCV of 15VDC and requires a dry contact closure (less than 100 ohms) to activate the output of the Invertec V350-Pro.

14 Pin Amphenols the Weld Terminals are controlled from pins C (lead 2) and pin D (lead 4). Pin C is positive.

6 Pin Amphenol the Weld Terminals are controlled from pin D (lead 2) and pin E (lead 4). In the 6-pin amphenol pin D is positive.
