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.
@@russbrown7895 BigFrost83 is correct. You melt the screen into the plastic. Well, the plastic melts, not the steel screen. But it strengthens the weld by a lot. Project Farm demonstrated this when he tested different plastic welders.
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 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
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?
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
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?
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 :)
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.
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
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?

Great no-nonsense, straight to the point, hands-on demonstration !! So helpful bro !! Thank you !!
The mesh is for reinforcing
I would love to see more tools being used trying to learn how to use tools for projects around the house This is a great video thank you

The mesh is to strengthen your repair when needed.
Good to know

Thanks it did help i bought one it's been awhile and haven't used it yet but when I do now I have a little to go on
Thanks big guy. I feel confident almost expertish. Great video

Just did this on my truck.. saved me a parts trip and lots of labor. $$$.

Pretty cool, had no idea plastic welding was an option.
Nice. I have the same Harbor fright tool. I use it to repair or modify my kayaks.
Very informative, didn't know you could do that
Thanks glad you enjoyed

Did it last
Mesh *can* be used for very large gaps .... it is recommended to cut patches and not try filling in the mesh.
I'm more familiar with hot air welding .
How long did it last?
I have cracks on my car dashboard. Do i have to remove that from my car before I weld?
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?
Still holding fuel no leaks.
Is there a plastic that will meld with different plastics, if you don't know the type of plastic you are working with?

Any update? It turn out good?
Did it work?

Think this kit would repair about a 3ft long crack in a blackwater tank on a travel trailer??
thanks!!! i did learn a lot.
Thanks man for the input.
Nice one 👍. Thank you

sorry that was mush = mutch LOL
Thank You! Great Video' Hope This Helps Many' Including Me' Because Money's Not Cheap!👍
The mesh is like fiberglass for reinforcement
Use it to repair laundry baskets, storage boxes & lids, cups, etc.
The mesh is to reinforce the plastic weld bro. You must use that.
the wire screen is to add strenth to your repair ... in case noone has said so yet , Cheers !!!

A link to where I can buy one?
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
The mesh is for repairing broken tabs.
Says so in the instructions…
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?
Did this kit from Harbor Freight work on your radiator repair? I have a leaking car radiator.
Yes it works on radiator... I did my 2010 s550 Mercedes benz hair line cracked near driver side air intake common crack on these vehicles
yepp easy hmmgm
Watch a You Tube video to find out what the mesh is for, lol. Sarcasm!
That’s a crappy job. You need penatration
