I liked Wagner the first time I visited and bought C25 gas for MIG welding, but my second visit left me much more impressed. I had just used up a tank of C25 (75% Argon, 25% CO2) from General Air Service & Supply in Fort Collins that cost me $127 (just for the gas). Went and exchanged it at Wagner for the exact same gas in the exact same amount. $67. That's half price, folks! So I asked about buying another cylinder, because it sucks when my sole tank runs out in the middle of work. They said they'd sell me one, but it would make a lot more sense to buy a used one on Craigslist or whatever and use it to exchange. And then they showed me where to look on the tank to make sure that it wasn't X'd out in a certain place that means the tank is unusable. Helpful people & great prices - I love this place! read more

Great outfit: Knowledgable folks, reasonable exchange price on CO2, and FULL 20LB refills on propane. It's a fairly long ride from my place in the mountains, but worth it, especially for propane. You'll feel the difference from grocery store exchanges -- typically 14 - 16 lb -- when you pick it up. When these guys say "20 lb" they mean it. read more

Good crew over there, no BS and won't take any. Only cowards don't use there real name!

Friendly customer service. They will refill Soda Stream canisters for a few dollars, ~$5, as long as the canister is not expired due to safety concerns. read more

We are in town and staying in our RV in subzero weather and needed a refill on our propane tanks. TSC and Uhaul were both unable to refill in low temp conditions but Wagner Welding was able and solved our propane emergency! read more

I'm a hobbyist fabricator and boy was I happy when my neighbor told me about Wagner. Their pricing on metal absolutely blows all the local hardware stores out of the water, and it's super convenient to get my (shielding) gas here. Employees are informative, polite, and honest: just yesterday I was there to pick up some supplies and asked for input on why my welding helmet was undarkening while plasma cutting. The guy helping me suspected my hood just wasn't sensitive enough, but instead of selling me on an expensive hood, told me most people use shade 5 glasses for cutting and sold me a pair for $10. That, my friends, is integrity. I will absolutely continue to use Wagner and strongly recommend them to anyone looking for a great welding supply store. Thanks for being awesome! read more

I have a mig welder that I was having some trouble with last week, mainly arc instability issues. After cleaning it out, it still wasn't working properly. Tried a couple more ideas with no results. It was only getting worse and I was beginning to think I would have to replace the entire machine. Luckily a friend of mine convinced me to take in into Wagner to have them check it out. They found a cable liner that was worn out that I somehow didn't see, replaced it for me, and I was out of there in 20 minutes. The guys in the store were really helpful, and they saved me from having to buy a new machine. Thanks again guys! read more

These folks are hardworking and customer focused. They have many options for buying/leasing/filling gas and oxygen cylinders, and they treat every customer, no matter how much they're spending, with respect. I'm grateful this business serves Longmont. read more

I filled my BBQ propane tank their yesterday and I am very pleased. It only cost me $16 compared to the exchange program at King Soopers and it feels like my tank is fuller. Thanks WWS. I will be back again for sure. read more

Customer service was terrible, employees rude, and dishonest. Brought a B tank in for exchange, and received one that had a faulty valve. Ended up losing most of the gas. Took it back in, and they acknowledged the valve was bad, but said I couldn't prove I had exchanged for that particular tank. On a subsequent visit, they refused to credit me for oxygen cylinder caps that I'd been charged for, and was returning. Will not use them again. read more

Have had my CO2 tanked filled 3 times and not once has it taken less then 2 weeks and I always have to call and ask if it's done. Never been called when tank was filled. Will go to a different company from now on as they act like they already have enough customers. read more
