My experience in resistance welding:

1977: Welding Engineer at Chevy Detroit Gear & Axle, 1st automotive Pertron control user.
1978: As employee #12, I started the Pertron Detroit office, for the automotive market.
1982: This new automotive business put Pertron in the Inc 500 , in 1982, 1983 & 1984.
1987: Start up of Automation Data Corp. ("ADC") specifying a weld control that Toshiba built.
1988: ADC sold more in their first year than Pertron did during all three "Inc 500" years!
1992: Started Update Technology to assist my friends in the automotive world.
2012: Still assisting with start-up and troubleshooting of welding lines,
          mostly for prototype and tier 1 automotive suppliers now.
2021: Retired and moved "Up North", but I can answer questions - email me!

While working for Pertron Controls Corporation:

Redesigned Pertron Control for automotive applications:
  -Patent Number 4,456,809
  -Modular construction = Data Entry Panel and Single SCR unit.
  -Cost reduced to 1/3 of the original (PWC-300) Pertron Control.
  -Addition of features; stepper, repeat, last weld data, and more.
  -Fully programmable using alphanumeric welding terms.

Worked with Chrysler ODMTC to produce their "SA2" weld control specification and became a 50% supplier of Chrysler controls (Medar was approved to this spec. to supply the other 50%).

Worked with Ford AAD (Div. of Body-Assembly) to become the first control to officially be approved to the "10TS" control standard.

At   ADC, our weld control introduced some "firsts" to automotive applications:

Drastic reduction of SCR failures
Last weld data, for the last hundred welds
Eliminated SCR condensation problem
Compact size (5"x 6"x 7" = 0.13 Cu.Ft.!)
Isolated cooling water from 480 VAC
Stepper boost applied every 2nd weld
Monitoring of secondary deterioration
SCR short trips breaker without control power
Memory backup without troublesome batteries


Direct interface to robots
Elimination of load resistors
Touchdown weld initiation
Network integrated
RS485 serial interface
Digital current calibration
Current set-up in K-amps
Current regulation

Most modern weld controls have adopted these features, so now they are available to all users.
After ADC closed, I assisted three other companies to second-source these controls.
Pretty slick, now you can buy the SAME CONTROL from three different companies, you gotta love it!

If you buy from any of these companies, rest assured that they will call me for any weld problem, long before the parts go to you.

Red entries are where Aaron Bacon has assisted. Aaron is able to instruct and troubleshoot in my absence.
Also Aaron is very computer-literate, and has setup the Moraine weld gun database in one weekend!
Just ask Steve Goebel, the Welding Coordinator, was he surprised with Aaron's work!

Green entries are new accounts Aaron has setup in his first year as manager of Update Technology.
