I am getting right into the swing of using the Touch n flow & Ambroid Pro Weld, the only issue I find is that Proweld isn’t quite as quick setting as I would like.
I have used it a couple of times in the “bit by bit” method when seams aren’t aligning properly, using slight pressure to align the seam when applying the Proweld & as it sets. The bottle states 10 seconds & while it has started to “go off” in 10 seconds, it hasn’t reached sufficient strength to stop the misalignment reappearing when I release the joint, so I am looking for something similar that I can still put though the Touch N Flow, but that welds a bit more quickly?.
Not sure about that. Yes, it evaporates faster but as it is a “hotter” solvent than Ambroid and Tenax, it tends to soften the plastic more and it takes longer for that softened plastic to re-harden…but it does also tend to make for a better “weld” by virtue of that. I use both Weld-On #3 and Tenax, and I’ve always found that hardening occurs faster with Tenax, so for some gluing tasks I prefer it to Weld-On.
You hit the nail on the head, it something which will harden more quickly, which I suppose means something which wont soften the plastic quite as much.
I just bought a bottle of Tenax, have been using a brush to apply it. Now for the touch 'n flow- what do you put it in?- is there a special bottle that the touch 'n flow fits on?
Dip the open end of the T&F applicator directly into the liquid. Capillary action draws it up into the T&F for you. Flip it over and let it flow to the needle tip…voila, ready to rock.
I’ve been using both Tenax and Weld-on 3. Both products have a place in my humble. Weld-on does indeed “weld” and while perhaps it doesn’t harden as fast as Tenax, if you’re trying to fit extremely small parts it I find that it helps when Weld-on creates a mini-plastic swamp for a few seconds giving you the chance to align the tiny bits properly before it sets. The effect is not so extreme that it damages the part. In general I find it preferable to any kind of super glue. You’re far less likely to glue the part to tweezers or your fingers. And a little goes a long way - just a small drop will hold a small part easily. One thing I haven’t tried yet is using Weld-on on a tank where a nice little weld might be just what the doctor ordered. It does evaporate quickly though. I use a small swizzle stick or tooth pick for application. I also have it in a bottle with a long and extremely fine tip. This stuff is as thin as it gets so you have to be careful, but you can get that micro-tip into anyplace if you use care. My quibble with Texnax is that it does not seem to create as strong a bond as either Tamiya liquid or Weld-on, but it is fast and likewise beats super-glue in most cases.
