  • new power supply

    Thinking about uprating the transformer on my sieg X3 conversion, it's running out of steam at high revs.

    Will this one do ?






    Should just be able to squeeze it in.

        Hmm. I'd be lookin for something with more amps.
        I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

            Out of interest what is the output of one of these in amps ?
            That copper block on the top is the actual winding.
            Its 1" x 1-1/2" solid copper and it has two 'turns' inside the box around a laminated core with the primary windings filing the bottom.

            Two people can 'just' lift one between them, so say around 300 - 350 #

            Knowing to company it's come from I'd say it's off something to do with welding pipe seams

              5700 Amps it says on the name plate looks like 50% duty cycle with 5 liters per minute water cooling.

              Its a spot welding transformer.

                Not obvious from pic one but one of the terminals is snapped off on this transformer that's why it's in.
                The break isn't clean and it then requires a new terminal.
                Again from pic 1 this brute is nearly 24" high and won't go on any of the mills and get a tool onto the top face,
                so think outside the box and rotate everything thru 90 degrees.



                So layed on the bed, horizontal attachment fitted with extended 1/2" cutter to clean the broken face up and then tap for two M12 brass studs to hold a new terminal block down.

                It was a panic job as the plant had come to a stop and in the rush forgot to take a pic of the finished job, this must be about #5 or#6 that has been done this way.

                Apparently they are supported from a travelling crane and they keep bumping them into things at the local pipe works.

                  Those 90' attachments come in very handy...
                  I use it alot with shoe mould work.
                  I will take some pics next time...I am getting better with the cam??
                  great job

                    Yes pictures are nice but I keep forgetting even though I take the camera into the shop every day because of the development work for the Chinese if I get an hour to do some.

                    This job was typical, I'd actually unbolted it and put the cutter away before realising it would make a good subject, hence no clamps and no retaining bolt for the collet.

                        Clumsy bastards.

                        I never have liked European wiring practices.

                            Looks OK to me the slippers should have the CE mark so that passes all tests

                              5700 Amps at 14V-19V at 50% duty cycle is what it says on the plate. Which fits in with the 100KVA rating.
                              It also needs 5 Litres per minute cooling water.

                              It would make a wonderful car battery charger
