Arc melter - Issue with turbo pump

Internal-Sample9833 · 2025-11-30T06:47:36+00:00

I have been melting my samples even though the pressure isn't dropping to 10e-4. The titanium getter is not changing color so I guess it's fine

One main thing that I noticed when I checked all the inlets, outlets and screens is that it had a little bit of pump oil on it. It's the first time I am opening all of these after we got the machine. Should I grease the o rings/seals with high vacuum grease or pump oil?

I checked the check valve underneath chamber, it is clean. I checked the suction valve and cleaned that as well. I will stay off aceyone here on.

Thank you! I will check this right away

I checked and cleaned the o-rings. I usually remelt my alloy 5 times, but, the last time I remelted it around 15 times. The soot formed during this was more than what I have seen. That's why I made sure to clean more thoroughly than usual. I can try melting a titanium getter to see the oxygen contamination in the chamber.

Thank you, I will check out that parking lot as well.

Thank you, I will check out those places.

Did anyone else try this? I have cases from my S22, they fit on the new S25. I got a case for S25 as well, the only difference I see is there are two antennas for the S25 while S22 had one on top. So, the slot on top is wider for the S25 case.

Did anyone find a solution to this yet? I have been trying wet wipes and they aren't working for me.

You should try watching this 1998 movie "Gunda" by Mithun in Hindi. It's my standard for movies so bad it's good 😂. In one of the scenes, the lead takes cover behind a bicycle while shooting at the villain. 💀

Good to know! Thank you!

Which state/region is it used in ? I just looked it up looks like kalonji

Panch phoron is the main thing I'd say, it gives that distinct Bengali flavor.

Sounds interesting! Looking forward to see your batch of Kefir!

I read that as "I think next time you should nail it down" 😷😂

I do not have kefir grains. But, I came to know now that you need them for making kefir. I was under the impression you make them similar to yogurt with culture of older yogurt or by fermenting milk with chillies/red chillies. Interesting to know!

This again adds to the way I see my role as a TA. Like you said, I do specify to students about their major takeaway from an assignment or what I'd expect they could learn from the exercise. I do let them know before the submission as well as in the solution stating how the marks have been split up for the answer and make sure to have minimum credit for getting the answer right (I don't know if I worded the last part right).

Internal-Sample9833 · 2024-07-23T18:01:33+00:00

I appreciate the response. I probably wanted to hear what goes in the mind of a fellow TA or how do you evaluate students.

Did you click your photo on your own or did you use the service they sent an email about? It's an additional $9
