SUMMARY:

The arc detector PCB’s PN-31419 Rev. “C” and 675280 Rev. “E” have been updated to Rev

“D” and Rev. “F”, respectively. The changes were made to:

• Simplify manufacture by incorporate common components and circuitry.

• improve performance reliability by eliminating mechanical switches.

• eliminate calibration problems by removing the calibration pot on the PCB.

The individual PCB P/N’s remain the same as above but the installation of PN-675280 Rev. “D”

PCB for the Digimatic II and DigiPulse Automatic will require a change in position of the

“Coding Plug” to accept the new Revision “D” board. More details and installation instructions

are provided below.

BACKGROUND:

Recently, users have raised concerns about the calibration standard and hence the

performance consistency of these PCB’s. The latest design and component modifications will

fix these concerns.

Previously, there were two arc detector PCB designs available having different circuitry and

components; one for the Robotic Interface and one for the Digimatic II or DigiPulse Automatic

controls. Both PCB’s were designed for the execution of similar functions for mechanized

welding control applications. Both boards had also seen several revision changes over the

years. It was time to consolidate and simplify there functions.

The old and new PCB’s are shown below:

Robotic Interface Arc Detect PCB

Replacement of the Robotic Interface Arc Detect PCB PN-31420 Rev. “F” is a simple remove

and replace which requires no additional steps.

Digimatic II /DigiPulse Automatic Arc Detect PCB

Replacement of the Digimatic II /DigiPulse Arc Detect PCB PN-675280 Rev. “D” requires the

“Key Plug” to be moved from position 11 to position 14 for proper installation of the new

Revision “D” PCB. See Below:

Key Plug in wrong position

To move “Key Plug” :

1. Gently pry up and remove plug (white) from card socket position 11

2. Move left to position 14 and press firmly in card socket. See Below.

3. Install Arc Detect PCB.
