I have the opportunity to get a big discount on my CNC purchase if I
can repair the Seller's band saw blade welder!!
Can someone tell me how to adjust a DoAll bandsaw blade welder? The
elecrical circuit is pretty straightforeward, but the mechanical
adjustment is really touchy.
Help!
Also, the anneal cycle just looks like a SPST switch. Is there a
trick to the anneal??
Help a brother get a discount!!
