I have just started my first experience of trying to join styrene material together using Ambroid Proweld with the Touch-N-Flow glass tube and needle applicator. However, on my second time of using the applicator, I could not get the Proweld to pull up into the glass tube. I suspect that the very small diameter needle is now plugged. After the first use, I cleared the excess liquid from the applicator following the instructions. 1. Has anyone successfully used the Ambroid Proweld with the Touch-N-Flow applicator? 2. What can I do to clean out the needle tip (since I assume it is now clogged)? 3. How do I keep the applicator needle tip from clogging? 4. Are there other weld or glue type materials that work well with the applicator?
The best way I’ve found for clearing out these things (I use Revell Liquid Poly Cement which has a similar “needle” applicator) is to use a piece of thin wire - push it gently down the tube to clear the blockage. In my experience the Revell cement tends to clog the tube if left for a week or so between uses, but if used more regularly it stays clog-free. If it’s available over there you might want to consider using it as it’s very good on most plastics and goes exactly where you aim it. Hope this is of help!
I usually find it’s easier to just use a 000 paintbru***o apply liquid plastic cement.
DITTO use a brush and throw away the needle.
