AC to AC/DC buzzbox welder conversion - any of these parts suitable?(pix)
I've dismantled what looks to me like a huge (probably 1987 vintage)
standby UPS (uninteruptable power supply). looks like it contains a nice big rectifier bridge (with four diodes and 2 'unknown' black things on it). also on the same unit are two small mini-circuit boards, which serve 'function unknown'. anybody with ANY clues whatsoEVER welcome to respond :-) becasue I'm in a 'zero visibilty fogbank' here.... here it IS: http://members.cox.net/dave_c/bridge_rectifier_etc/ also found within same unit a huge transformer, which might become (after being partially unwound then part REwound) the core transformer of a 'homebrewed' welding high frequency converter ('later' :-). comments appreciated as to wether or not some/any, or none of these parts could be suitable for purposes intended (mainly the AC to AC/DC miller thunderbolt220 volt buzzbox conversion purpose), and, if that's 'totally unknown without their specs', what test procedures I could follow to determine wether or not these parts are a. in fact still 'good', and/or b. how their specific capacities,'specs', or ratings can be determined? (when not found on net) please no "just buy a new or used one" replies after circuit design etc I intend to house the AC/DC "adapter" in a seperate (probably old computer) case. I'm not even sure IF (one of the components pictured) *IS* a bridge rectifier, jus' for starters :-/ thanks for educating me box ps-some of the threads below gave me this hairbrained idea ;-). http://groups-beta.google.com/group/...2a632e04b91bad thread: change your AC welder to AC/DC- *how* http://www.tigdepot.com/products/p35TD-BBTF.htm Mr Tig-conversion ideas for buzzbox to AC/DC/TIG box.... http://groups-beta.google.com/group/...dc5125b81d34d7 another thread on AC/DC diodes/chokes and bridges http://groups-beta.google.com/group/...15305e672 66e using SCR to change AC to AC/DC welders...maybe http://groups-beta.google.com/group/...8c25a7372 c9b or maybe use 150 amp diodes in the bridge http://groups.yahoo.com/group/Weldin...s/message/2927 guy built a BULLETPROOOF bridge rectifier.... and some of the "high frequency unit - build it yourself idea" threads: http://groups-beta.google.com/group/...1e726748458399 thread re hi frequency DIY http://www.geocities.com/CapeCanaver...tarter/hf.html Welding Arc Stabilizer-homemade DIY high-frequency ADAPTER++++++++++++++++++++++++++ http://www.hotrodders.com/t43272.html TIG "arc starters"-thread http://www.electronics-list.com/Top_...struction.html tersla coil-Construction, Best Links (tesla coil primary circuits and "high frequency adapter welder" boxes are VERY similar, components-wise, according to some threads) http://www.electrophile.8m.com/bargsors.htm The Basement-obtaining tesla parts VERY CHEAPLY-how |
