Watchmaster ultrasonic cleaner manual

If so, they may have the manual. It's worked for me. I have a watch master with electronic tubes, no transisters. Has several SS cups for each chemical. Is this the same as yours? Mine must have a bad capacitor in it as it gets hot and then quits and you have to power off before it blows a tube or fuse.

If the same I can mail a copy of the manual if I can find it. Byung Moo Yu New User. Aug 4, 1 0 0. Anyone know where I can it get serviced? Thank you. Sep 28, 1 0 0. I can help you. Most likely problem is the tubes. You might also want to contact www. Dec 13, 1 0 0. Thanks, Walt. You must log in or register to reply here. Find member. Latest posts C.

The machine itself can only hold two ultrasonic at a time, so there is an optional clip-on cup holder so that you can add a second ultrasonic rinse cup to the cleaning cycle. All in all these machines are very reliable and fairly simple to repair in most cases. Despite lacking the convenience of a fully automated cleaning cycle, the small size of the WT as well as the durability and excellent results the machine provides, cause many watchmakers to leave space on their benches for this old workhorse of a machine.

There were actually two models of this style cleaning machine that preceded the WT as well as one model of the same style that followed it. The models that came before were the A1 and A1T respectively. It is highly advisable to avoid the WatchMaster A1 as it has a tendency to overheat and burn up.

The A1T fixed whatever problems caused the overheating. I believe I have read that it was something to do with the transformer used in the A1. The A1T is functionally the same as the WT with some minor electrical differences. The upper area where the drying and dip rinse cups are located was red while the body of the machine was a matte grey color with a wrinkle texture.

All three operate at 32kHz, a frequency that sits between the more commonly used 28 kHz and 48 kHz frequencies. You might not think that damaging plating is a real concern but, on new ultrasonic tanks, a fairly common test of cleaning power is to hold a piece of aluminum foil just off the bottom of the tank and watch as it punches holes in it.

Even the thickness of the gold in gold filled pocket watch cases well past the end of their prescribed twenty or thirty year warranties can be pretty thin if the watch spent time in a particularly abrasive pocket. One of each model are working and the second Mark 2 is the unit I keep in case I need to swap out parts. I love these for their simplicity of operation and their well implemented engineering.

My only complaint is that you cannot the ultrasonic switched on anywhere near where you have your timing machine set up. The final page before the back cover shows the schematic. Like Like.
