I found this Miller CST 280 at a flea market for $15. He said he did a building clean out and it was part of the contents...and he knew nothing else about it. It was assembled and attached to a rack type thing...as if it was hung from a steel beam while in use... maybe. I have several Welding machines, but I've never owned an Inverter machine before. I have it apart to blow out the dirty interior, straighten out the bent Dinse plug panel and change the power cord. It looks like these retail for about $2500. It would be great if this thing still worked for only 15. Is it possible ?! I guess I'll tinker with it and put it back together and try it. If anyone can think of anything I should know before I proceed with the project, I would appreciate it. Thanks.
