the steel mesh is to reinforce the plastic you are welding ..thank you for the vid i bought 2 of them the trawl welder and the hotwire welder i don't bother with glue any more this is FAR better
hey just drilled a .125 hole in the Focus gas tank; so tomorrow i'll go over to HF and "do likewise"! self inflicted wounds hurt worse in my world! thank you for the video ' cause pulling that tank is NOT WHAT I WANT TO DO! pray to the LORD that i get it right; thanks again for the video!
I see you ran into the same problem with your soldering tip rod bending under the heat and pressure, it looks like a little flaw in Harbor Freights tool, I just bent mine back and it still works. You did a nice job using yours, it takes a little practice to get smooth results. If you are plastic welding Honda fenders it's good to find some of the same material to weld with. I found a frisbee disk that was the same red color and cut into strips to use as welding rods. It worked great, then just sanded off until desired smoothness.
As you can see the tip of the welder is bending because the metal used is too soft and too long and risk of breaking. The solution to this problem it's to cut the welder tip of around 7 mm. This way the welder tip will be shorter what will reduce stress on the tip and the risk of breaking it. I f you have a thread on the tip , you can add more thread with tap and die kit, this will allow you to screw the rod deeper and remove 7 or 8 mm of the tip
I had the same one as I watched your video yours did just what mine did . The end or tip got so hot the it seam to have bent , but in reality the plastic that holes the tool together melted too. Had to take mine back and they replaced it. But same thing happened again
Punctured a hole into my fuel tank on my diesel truck, have a hole the size of my index finger. To replace the tank is $1500 so I’m gunna try and fix it myself for $16, thanks for a great video
Worked alright, if you doing on a gas tank make sure it is completely dry think I was too much in a hurry to do mine it held for months but made a little drip so I got over the drip and just decided to replace the whole tank with another one. But ya if you take your time and do it right it should work fine
The mesh is used to do large areas like an actual quarter size hole ETC, you can use it to strengthen but the idea is so you can apply it over a hole without having to use to mush of the plastic sticks, nice try Ryan :)
Thank you for sharing the tips. I have a cracked water pump plastic housing and I tried welding it with a regular soldering iron but it still leak oil. After watching what you did, I think I will give it another try. How is the tank doing so far?
O I thought I should add the procedure on how to use the mesh, cut slightly overlapping piece of mesh and first weld it on the outside of the mesh edges, then proceed to cover the mesh.
I have the same welder and am learning how to use it myself. HF does sell replacement repair sticks but they are not as wide as the originals and come in a few different colors, but not black. My issue so far is my inability to smooth the surface out w/ the welder and when that doesnt work trying to smooth it out by sanding or trimming w/ xacto knife etc. Neither seem to work well on plastic. Any advice?
I used this on a radiator... dont know yet if its gonna hold because of temperature and pressure well see.. anyone used a plastic welder on a radiator?
harbor freight smh he said it like 10 times u can also order it from ebay or get it at home depot online idk about in the store but the one at home depot cost 4 dollars more and comes with alot more shit in the kit
