    Re: Modifing a Battery Spot Welder because of Controller Issues

    The parts came in and I will see if I have time over weekend and see if I get something working
    9 PC LCD Monitor
    6 LCD Flat Screen TV
    30 Desk Top Switching Power Supply
    10 Battery Charger Switching Power Supply for Power Tool
    6 18v Lithium Battery Power Boards for Tool Battery Packs
    1 XBox 360 Switching Power Supply and M Board
    25 Servo Drives 220/460 3 Phase
    6 De-soldering Station Switching Power Supply 1 Power Supply
    1 Dell Mother Board
    15 Computer Power Supply
    1 HP Printer Supply & Control Board * lighting finished it *


    These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

    1 Over Head Crane Current Sensing Board ( VFD Failure Five Years Later )
    2 Hem Saw Computer Stack Board

    All of these had CAPs POOF
    All of the mosfet that are taken out by bad caps

      Well I had time to work on this battery spot welder exterior controller

      The test results went well and the concept will work now I have mount everything in the controller case and fix the transformer and welder fixture and hook up amp meter and volt meter

        Update

        Well things did not go very well not everything would fit in this case so I had to go with plan “B” which is to cut down the the heat sink and put the triac back on the controller board again —>

        this actually went better than I thought it would in that I cut the heat sink the width as the triac and a piece of non conducive paper that is used for making battery packs and put it on the circuit board so it would not short out

        Now I have figure out how I am going to mount the small controller transformer and where

        I also have to figure out how to mount the amp and volt meters on the face plate of the welder which will be a challenge because of how the welder arms are

        There is also another challenge with welder arms because I change the configuration of the transformer secondary winding wires and where they go so I have to buy some welding wire that fit the welding arms

        I will post some pictures when I get done with this project
