Mac, I bought this welder, which is a pro-level plastic welder, because our wells are drying up around here, and rainwater collection is going to be my only source of household water in the next few years. I have a fair amount of plastic welding to do for the massive collection and treatment system I've been building for the last several years, so I sought out a pro-level solution...That particular welder looks a lot more sophisticated than the twist and pray HF model I've got. I like that you can digitally set the temperature...which is critical for welding plastic.
Very accurate statement, Mac. Just like welding metals, you have to know what you're welding and then use the proper settings. Leister makes a non-digital (just a knob to turn) gun exactly like the one I bought for a few hundred less, but the salesman told me the digital would be worth the extra money. He was right.The second most important thing is figuring out what plastic it is so you select the right welding material and temperature.
I started making some cable tie organizers. I wanted to organize my cable ties, and I assumed someone would have the perfect solution for me. Nope. I couldn't find anything even close to what I need, so I decided to make an organizer out of PVC. I cut some 2" pipe into different lengths. Then, I welded them together:

There's a second row that I welded onto that row, but I forgot to take a picture. I've got some PVC sheet on order, and I'll cut a bottom out of that, along with some pieces to weld on some mounting tabs. It'll be wall-mountable when complete...
It just uses very low flow, dry air from the compressor and dryer.Does that thing use C25 or pure Argon?
Geez - I wasn't even trying to spend your money this time, Jeff!Edit: Plastic Welder...Hmmmmm......

Some burning plastics create hydrogen cyanide, but welding plastic doesn't involve combustion. You just heat it above the glass transition temperature, which is well below the combustion temperature. The fumes while welding are not bad at all.I imagine setting just enough heat really cuts down on the noxious fumes and smoke. Burning plastic makes hydrogen cyanide,bad stuff!
I have seven tanks. All but one are HDPE tanks, which is why I bought the plastic welder. The big one (30,000 gallons) is a Pioneer brand tank. Like most quality rainwater-collection equipment, it's made in Australia. Australia leads the world in rainwater-collection technology. That tank is a a corrugated steel structure with a plastic liner. Like your friend, my total capacity gives me a year of water storage because we have Texas-sized droughts down here.I forget what you have for water storage. Have you looked into the large tanks with liners? I helped a friend set up a 50k gallon tank. Their spring is seasonal and rely on a large amount of storage to get through the dry season.
About 37,000 gallons. We are very water-conscious and only use about 60 gallons per day.What's the total capacity, Scott?
Been running the chipper into an IBC and spreading the chips on the mud outside the shop.

Makes you want pancakes house, doesn't it?Ever since the movie "Fargo" I can never look at a wood chipper the same way.
I finished the PVC cable tie holder and mounted it to a toolbox:

PVC is not nearly as easy to weld as HDPE is. It doesn't flow very well, so the welds are butt-ugly. On top of that, welding around the circular pipe was tricky. I had to change directions on every tube at the base. I doubt that I got full fusion everywhere, but I think the welds are strong enough for this purpose, though. At least I won't misplace my cable ties any more!
