Work Voltage Sensing

The standard Power Wave 455/STT is shipped with the work voltage sense lead enabled.

For processes requiring work voltage sensing, connect the (21) work voltage sense lead (K940) from the Power Wave work sense lead receptacle to the work piece. Attach the sense lead to the work piece as close to the weld as practical, but not in the return current path. Enable the work voltage sensing in the Power Wave as follows:

WARNING

• Do not touch electrically live parts or electrodes with your skin or wet clothing.

•Insulate yourself from the work and ground.

•Alwoays wear dry insulating gloves.

------------------------------------------------------------

1.Turn off power to the power source at the disconnect switch.

2.Remove the front cover from the power source.

3. The control board is on the left side of the

position if the work sense lead is present.

 

 

 

 

5.Replace the cover and screws. The PC board will “read” the switch at power up, and configure the work voltage sense lead appropriately.

Electrode Voltage Sensing

Enabling or disabling electrode voltage sensing is automatically configured through software. The 67 electrode sense lead is internal to the cable to the wire feeder and always connected when a wire feeder is present.

CAUTION

Important: The electrode polarity must be config- ured at the feed head for all semi-automatic processes. Failure to do so may result in extreme- ly high welding outputs.

------------------------------------------------------------------------

POWER WAVE TO SEMI-AUTOMAT- IC POWER FEED WIRE FEEDER INTERCONNECTIONS

The Power Wave 455/STT and semi-automatic POWER FEED family communicate via a 5 conductor control cable (K1543). The control cable consists of two power leads, one twisted pair for digital communication, and one lead for voltage sensing. The cables are designed to be connected end to end for ease of extension. The out- put receptacle on the Power Wave 455/STT is located beneath the spring loaded output cover at the bottom of the case front. The input receptacle on the Power Feed is typically located at the back of the feeder, or on the bottom of the user interface.

For convenience sake, the electrode and control cables can be routed behind the left or right strain reliefs (under the spring loaded output cover), and along the channels formed into the base of the Power Wave, out the back of the channels, and then to the wire feeder.

Due to the flexibility of the platform the configuration may vary. The following is a general description of the sys- tem. For specific configuration information, consult the semi-automatic Power Feed instruction manual.
