This morning worked with Doug Mason to set-up an alternative ultrasonic welder for the connector on MP10.  After a fair amount of tweaking, this machine which is the old Air Ten Truman Cell Bracket welder, could work in a pinch with some modifications.  We finished with 30-40 parts in a row with no failures. 

 

About 10am, Keith Raiford with Branson Ultrasonics came in to work on the Branson Model 910IW welder on MP10.  After a thorough investigation we found the following problems with our old welder:  The main power supply for the welder was dead w/ no output, (A new power supply was installed) The upper exhaust fan in the cabinet had failed, (Both fans in the cabinet were replaced to protect the ps)  The horn cylinder was replaced, The trigger switch was replaced, The trim pot on the front of the machine was jacked up and we replace it,  Both air regulators on the front of the machine were broken and we replaced them.  We bummed a packed of mylar washers from him for the horn,  Went through the horn stack and serviced it,  Tuned the machine, aligned the horn and fixture and started welding parts.  Potter was happy with the parts.  The following set-up exists:

 

38psi air pressure

1.5 weld time

.050 on hold time

5.5 trigger

#4- had a problem with temp zone#2 it was a mercury relay stuck. Pecked on it and it started working again.

Continued working on new press 26 water and New press#1.

 Leave MP-10 down ;   Branson tech will be here in the morning.

 

MP-2 – They hung the supply tank again. You have to crack the eject valves open so the machine & mold plates both move, so it can read limits.

 

MP-19  Someone broke the glass on the controller.  I ordered a new glass & touch pad . It will be here tomorrow.

 

MP-8   Cores not working--- after checking everything, it ended up being one of the hydraulic quick connects.

 

MP-25   Ran a new T.C. wire for the nozzle tip heater.

 

MP-17  Oil was running out on the floor AGAIN.  Cleaned up AGAIN. Needs oil added.

MP20 broke the ejector plate bolts. Replaced them and started back up.

Hooked up the cores and ejector hoses and switches for the tank mold in MP2 but we couldn't figure out the settings to make it read the ejector switches only

The Branson welder on MP10 stuck a couple of times like it was still trying to weld when the head came back up. The operator tapped on the side of it and it quit. Later on in the shift it quit welding altogether. I checked everything out and tried a new relay in it but still couldn't get it working.

Mp #3-

Stopped during production with clamp closed. The machine acted like it had lost its pump and nothing was working at all. We tried probing the variable pump load valve and got 3000 pressure so we started looking at the electrical and found a fuse blown. We changed it and it blew as soon as we started the pump. After tracing out the short, we located the coil bad on the "Decrompress Hoses valve A156". We replaced the fuses and used the coil from the sled retract valve to open the clamp and check things out. When we took the coil back off the A156 valve we noticed that it was extremely hot.

After looking at the output card, I noticed the output for A156 (slot 5/#10) was staying on constantly. I wanted to isolate it to the output card so I swapped it out with the card from slot 8. Well, it was not the cards.

So I compared it with Press#5 to see what it was doing and 5 was not coming on at all in automatic cycle. So, I stopped it long enough to see if it came on in Manual or when the pump was off. It didn't come on in either case. So, at this point I went to the sequence chart and looked at when it should be on during the cycle. It does appear to be on throughout most of the cycle except for a short break between decompression and extruder run.

So the dilemma I am faced with now is why would the control be energizing this A156 output all the time? Is there something feeding back data to the control that would make it respond this way? Maybe a bad transducer or another input signal?Or a bit set in the control? Maybe needs reprogrammed?

Call if there are any specific questions about this or anything else.
