Hi, I'm new to soldering and ordered a CSI-Station1A soldering station from Circuit Specialist Inc. I also ordered 2 extra 0.8mm chisel soldering tips but they are not in stock and are on back order. Does anyone know of other brand soldering tips that are compatible or interchangeable with the CSI-Station 1A? I've emailed CSI but they haven't responded. The station looks similar to the Hakko 936 but I don't know if the tips are compatible. Sincere Thanks, Don
