Capable of handling any MIG-MAG pulse welding challenges the welder has to overcome or can throw at it – our new Lorch S-series allows the welder to adapt the machines to his specific requirements and preferences. Then I installed a set of Lenco LDC-50 Dinse-style welding cable quick disconnects rated for 250A on the welding leads. I highly recommend these modifications. The capacitor is supposed to be installed just inside the welder in parallel with the welding leads and ‘com’ grounded to the welder chassis.
Guns and Accessories do NOT have a Code Number, please use the Product Name Search. The original thread and schematic mentioned a 600pF 2kV ceramic capacitor, but I tried 0.5nF and 1nF 500V in my test circuit. With the front panel set to 120A, current could be increased smoothly from 0A to 60A, but then it would latch high at 120A and it could not be turned back down. The TRIAC approach discussed toward the end of the first thread is interesting, but I could not find any TRIACs that handle enough current to support the welder’s full power, let alone with much headroom.
