2.  PROGRAM STEPPER LINEAR STEPPER SCREEN

Linear steppers track the number of welds and increase the heat at pre-programmed intervals. The IWC uses a linear stepper profile table, that you can set up, to identify how much and when additional current is applied to a weld.

To use a linear stepper, you must perform the following steps:

  • Create a linear stepper profile table.

  • Activate a linear stepper within all applicable welding sequences by inserting its activation function.

For further detail on how to use linear steppers, refer to the MedWeld 3004 Integrated Weld Control Technical Reference Manual.

3.  PROGRAM STEPPER SURE-WELD STEPPER SCREEN

Sure-weld steppers are intelligent steppers that monitor changes in power factor and either increase or decrease welding current based on these computations.

To use a Sure-weld stepper, you must perform the following steps:

  • Set up a Sure-weld stepper profile

  • Activate a Sure-weld stepper within all applicable welding sequences by inserting its activation function.

For additional information about how to use Sure-weld steppers, refer to the MedWeld 3004 Integrated Weld Control Technical Reference Manual .

4.  PROGRAM NET ADDRS SCREEN

Medar's local area network (MedLAN) is a proprietary RS-422 serial link used to interconnect robotic, hard tooling and portable gun welding controls throughout a plant for the purpose of data programming, monitoring and verification.

MedLAN's protocol designates network addresses #0 thru #29 for welding controls and network addresses #30 and #31 for master devices such as their Weld Support System (WSS) or Data Entry Panel (DEP).

Note

Avoid using MedLAN network addresses #30 and #31 when changing the IWC's network address.

Changing the MedLAN address does not require any cycling of controller power for the change to take effect.

An alarm will be posted to the alarm log whenever the MedLAN address is changed. The alarm message will indicate both the new and prior addresses.

Note

When an IWC is reloaded from factory defaults, its MedLAN network address will be #255 (an invalid weld control address) removing its ability to communicate over the network. Therefore, you will need to reprogram the address to a non-conflicting address for proper establishment with a master MedLAN device.
