JOUNJIP Standard Plastic Welding Kit- UL Certified Welder 80W- Professional Grade Plastic Repair Kit for Automotive Car Bumper, Kayak, Tank Repair

This welding kit is set up real well for plastic welding. The welder gets very hot and makes welding plastic much easier with better flow of the rods. I repaired a large black trash barrel (one with flip lid for trucks to raise up and flip over to deposit trash). My barrel ended up with about a 12 inch split of the lid from the back corner heading towards the middle. Needed to repair this crack or it was just going to get worse and these barrels aren't cheap. I used the silver tape, to seal the top side and then used the black polyplaz rods with the included wire mesh and larger triangle tip to weld and seal the underside. On the top side, I created a groove with my dremel tool along the crack and then used the boot tip with a PP black rod to fill in the groove and flattened the the plastic to create a relatively flat surface. I then used an orbital sander just to smooth out and to practice. It's ready for a quick paint (not needed but once again just to humor myself) and the trash barrel looks so much better and the lid is now rigid and feels like there never was a crack. With regards to customer service: When I got the box, I noticed it was missing the smaller triangle tip and I got a hold of customer service quickly. Jon was so helpful and said he would get a welding tip right out. He did and had the tracking number for me that day. If you are price comparing, I think you will see that this kit is much better quality and the items included deliver better bang for the buck. I added some photos to show work in progress. I will do some final touches to smooth out and blend some paint in (really not needed for this trash barrel but just to use some more tools! Pictures show the wire mesh on the rough underside but on the top you can blend in with the boot iron and fill the crack with the PP rod. Did some rough and medium sanding and it looks like a used trash barrel and is as strong as when it was new.

Excellent kit, been using it for over 2 years now and it gets the job done everytime and this was my first time doing plastic weld. The tip heats up in about 4 minutes and is ready to use but can get really hot and i have to be careful not to melt other plastic. The different heads are practical and allows or getting into corners

As others have mentioned, the 'foot' on this is made of soft metal and will bend very easily. I anticipated this when I started using the tool and was careful not to apply too much pressure. Even so, after about 15 minutes of use, the foot was noticeably bent. Another review had mentioned drilling a hole down the shaft and inserting a drill bit to stiffen the foot. This worked for me. I didn't solder the bit in place but rather just cut it so it sticks out slightly from the top of the shaft. That way, when the shaft is inserted into the recess in the end of the tool handle, the bit is captured and can't go anywhere. A 5/64 bit seems to be about the right size for this. I used it a fair bit after inserting the drill bit with no sign of bending. I think this is a permanent fix. I'm giving it 4 stars because I anticipated I might have to make this fix. I looked around for higher quality tools that wouldn't require the fix and found them to be priced at least twice what this one. The rest of the tool seems to be good quality and there's a decent supply of plasting welding material supplied. If you're willing to put in a bit of work and sacrifice a drill bit to fix the foot, this would make a useful tool for a modest price. Without the drill bit fix, I don't think I would get much use out of it before the foot broke off or became so bent that it's hard to use.

The Jounjip welder worked so much better than JB Weld. My wife dropped the cordless blower which cracked the end near the motor. I applied a thick coating of JB Weld original on the inside and out and then let it cure for two days-popped apart when placed back on the blower. Jounjip with wire mesh and other areas with just the weld stick held up perfectly. Temperature was 500+ degrees and easily melted the HTPE ABS and the plastic fill rod. Glad I got it during the Black Friday sale.

The tool is basically the same as a low wattage soldering iron or woodburning tool. But that's a good thing. Because it's simple. It's a rugged, time-tested design. And if you've used any of those tools - using this is very much the same. The kit is well arrayed. There's a standard bent-metal heating iron rest. It works but leaves everything exposed (hot) and if you have kids or pets that like to get close while you work, you have to be careful around the unit when it's hot. I always just use an empty soda can on its side. Works like a shield and rest. The kit includes aluminum tape which you usually see on automotive plastics that come near heat. This is listed as "repair tape" to be used to hold seams together while you're making repairs. There are a couple strips of stainless steel screen. These are intended to be permanently melted into the plastic across any cracks as reinforcing mesh. Some strips of polypropylene and rods of polyethylene are included. You can buy strips or rods of other plastics like LDPE and HDPE online if you need to repair those types of plastics. The included tips screw into the head both for good heat transfer and strength. There are flat "ironing" tips for melting and smoothing plastic. And there "welding tips" with a 1/8 inch hole that allows you to feed plastic "rods" directly to the repair as you apply the heat to melt and weld the plastic. The keys to a good repair are (1) making sure you're using the right plastic for your repair strip/rod. Polypropylene will not make successful repairs on HDPE for instance. and (2) getting a good melt (so don't move the tip too quickly). There's a wirebrush and some sandpaper which you'll use if the plastic item you're repairing has junk or embedded dirt. These are standard things you can get anywhere as they wear out. All in all, I've made some successful repairs on a Polypropylene cup holder in my UTV and a couple HDPE repairs on a plastic wheelbarrow body. Pleased with the purchase. I think you will be too, with a little practice.

I've used this with success on three projects - all welds have held for the three to six months since I did them, so very happy with the results. My welds are a little ugly due to my lack of skill, but all are solid. Watch a few Youtube videos if you want to see how it is done. You can find extra "welding rod" in your recycling bin. Find a chart for what the recycling numbers mean on the internet and then look thru what you are throwing away.

I used this for the first time today and I was surprised at the strength of the repair. This works much better than the hot staples I'd used on previous repairs. However, the brass tip on my welder became very soft as I was using it. The brass tip is threaded, and screws into the handle where heat is applied. The threads became so soft that the shaft with the threads began to elongate slightly. I'd screwed the tip into the welder until there was no gap between the two, but as I used it, a gap began to form on one side of the tip. I then noticed it was angled slightly. So, I used the welder to apply pressure from the opposite side to bend the tip back into alignment. This happened a couple of times over the ten minutes I used it. Then, the tip suddenly and completely broke off, leaving the threaded shaft inside the welder. This welder is so effective and useful that I plan to purchase a replacement. I'm not happy with the durability of the brass tips, but otherwise it does what it's supposed to do.

I have test in 110V 50hz it work perfectly, i'm in France but i'm glad it's work really good ! Thank you Jounjip team.
