Bit late to the party but this is an extremely informative and demonstrative video and helped answer a lot of my questions regarding the process of resistance soldering. Sent by Paul from Scale Model Workshop, you are a great presenter my good sir.
I needed this 2 months ago, would have saved me so much grief and frustration; 2024 is the year I went back to buying brass kits and attempting to make use of that blasted RSU.... what a bleeding mess..... oh, now I know why. Thank you.
Excellent video. If only all videos explained things so well. I suspect David is a naturally tidy and organised person but maybe we can all learn from that. Despite having had a LRM solder unit for many years I learned some things.
Superbly simple and helpful presentation; very easy to follow and understand - thank you. (One small niggle, however, it should be 'complementary' , not 'complimentary'.)
I've been soldering all my life but have never used or even seen an RSU. If I had, it would have saved me a lot of time in cleaning up parts or "inventing" ways of soldering stuff together using a combination of white metal solder, tin/lead and tin/copper to prevent the models from falling apart. David applies his flux with a needle. I use a piece of 0.8 mm wire or even a needle to apply flux to small, delicate, joints. Just dip the tip of the needle in a bottle of flux and then touch the joint. By magic of capillary flow, the flux will get inside the joint. This makes sure that (most) of the solder goes into the joint and does not spread across the remaining part of my work.
Superb clear tutoral , I for one that put my resistance unit away as i could not get on with it , I realise now where i have been going wrong ! Thanks very much
A new world opens up to me, I will experiment: despite knowing arc welding, I had never thought of applying the same principle, even if slightly different, on small parts. I can find some suitable transformer at least to test, among my electronic scrap. Great explanation indeed, thanks to you for the video and to Paul Budzik for redirecting me to you.
I´d like to thank You Sir! This is excellent. I have an RSU standing in a shelf for years, not using it. I have searched for a "power" layout and what do I find at the end - a chart over it. From that I found a PDF on scalefour. Thank You!
Also got here via Scale Model Workshop. Thanks to Paul and thank you David for your most informative presentation. I take it electric shock is not an issue? Asking for a friend.
Very nice video, I doesn't know this type of soldering 😊 looks very useful, would this solder Technik work for self made wire lugs, to putting solder inside and outside? Regards
Sorry for the delay. I have not been able to post replies. Look for the Scalefour Society and look under 'Stores and Traders' for London Road Models. They have handles and rods.
I wouldn't, is the short answer. The heat generated is too great and will melt the white metal which is why, in the video, I heat the brass and use it to convey heat to the joint when soldering white metal parts, making sure the probe does not touch the white metal casting. Stick to a conventional iron for white metal to white metal.

I’m here on the recommendation of Scale Model Workshop! So informative, thank you!
Paul over at Scale Model Workshop sent me here.
Same here!
Me too
And me!
Me as well.

Paul Budzik brought me here! 😀
Extremely well done and informative. A must view for any modelers wanting to solder brass etchings and detail.
Thank you very much. I have been an admirer of your videos from which I have gleaned a lot of useful material, so many thanks to you.

Fun seeing two forces of nature in modeling interact in the comment section. 🙂
great information im glad i saw your video before trying anything thanks

What a wonderful and informative video. You are a great communicator, David. Thanks for sharing on RUclips
Very helpful video
This was the most pleasant and informative half hour of education in my entire life
Thank You
Scale model workshops brought me here too 👍👍👍👍👍
Thank you David for this excellent and informative video and to Paul @ Scale Model Workshop for the recommendation 😉👍
Thank you David, I think you have captured the technology perfectly, found your site through Paul Budzik
Just starting to use my Graskop RSU for 1/35 photo etch and found this video the best so far‼️👍👏
Excellent tutorial! Much appreciated by a novice! Thank you!
Superb clear tutoral , I for one that put my resistance unit away as i could not get on with it , I realise now where i have been going wrong ! Thanks very much
Great. Glad to help. Happy soldering!
Old school tutorial. Nice.
That is a superbly crafted video of your excellent metal crafting. I haven't tried resistance soldering, but this may inspire me to do so.
Interesting, informative and very good presentation.
Thank you, very informative. I have had an RSU for years and used it infrequently. Your video has given me quite a few ideas now. Thanks again.
Then the video has done what I wanted it to do. Thank you.
Very inspiring video thanks 😀

Excellent!
Well done! Very helpful as well as inspirational.
Well done tutorial! Looking forward to practicing and using my RSU for future projects.
Excellent video sir
Excellent Video! Thank you!
Thank you.
Excellent video!
Excellent tutorial 💯

Jolly good. I am pleased you have found something useful here. Now you can get on and use the tool!

Shocks not an issue. Glad you found the presentation informative.
@@richarddavid7800 thanks.
very interesting,,, can i ask where you got your probe and cable from cheers,,,
Very nice video, I doesn't know this type of soldering 😊 looks very useful, would this solder Technik work for self made wire lugs, to putting solder inside and outside?

I am not very sure what you are asking.
What size wattage is recommended for scale4 RSU units?
15:08 Tinning
Where are the handles that hold the carbon rod available?
Sorry for the delay. I have not been able to post replies. Look for the Scalefour Society and look under 'Stores and Traders' for London Road Models. They have handles and rods.
Soldering white metal to white metal? How would you go about that?
