Wagner Welding Supply

Solid spot for any compressed gas needs you may have.

Nice staff.

Best place in town to refill your propane tanks because they actually fill them to 20lbs (unlike box store tank swaps, where you actually only get 14-15 lbs in a 20 lb tank....)

I have been using them for about 9 years now. They are courteous and efficient. I started going there because they will refill CO2 for my SodaStream cartridges. They convinced me to upgrade the cartridge to a bigger one (with an adapter). This is saving me some money, thank you! I have since started filling my RV’s propane there too.

This is a great local company worth doing business with and supporting.

Super fast propane refills at a very good price. Just drive around back next to the refill station and you'll be in and out in less than 10 mins.

Great experience had an issue with a settling tank and they replaced it for your charge. This is why I've always come here and this is why I will always come here. Great selection of steel here too.

I went in with a bunch of questions. You never know how that is going to work out. The staff was friendly, professional, knowledgable and helpful. Prices were much better than General Air in Boulder. I'll be back.

Great people. I brought back a tank with what I thought was a broken connector. It turns out the problem was on my end, but they were super nice about helping me find the issue.

I’m a out of stater and happened to be caught in a snow storm and needed a propane refill...found this place and they were very friendly and upfront about my tank having a seal leak and repaired it for me right there! Prices were very reasonable...this place is great! Thanks guys!

This review reflects on the Welding shop-
Excellent service, availability of various options, and quality material. From welding jacket, I mean "real ones", sheet metals, and welding necessities. Well recommended.

The people who work here are amazing and have gone out of their way multiple times to help my family out personally. I cannot express enough thanks to them for helping us in a time of need. Today they clearly put being a decent human being ahead of business. It has moved us to know that good hearted, quality people still exist out there.

Thanks guys for filling our propane tank every week to ensure Longmont is fed. Best propane refill place!

Best place to fill you're bbq propane tank!! Friendly fast service and its only $18.90 cheaper than any place and they fill up 20 pounds not 15!! Great service!

Brought my Sodastream canisters here for refills. Quick and easy and they were full just like the ones you get at the store but for $5 instead of $15 each. Will be coming back.

Refilled my SodaStream CO2 carbonation cylinder for about $5. Normally I do a cylinder exchange at Bed Bath & Beyond. But the whole covid thing has left them out-of-stock. So I decided to stop in to Wagner, and they said they could fill it no problem. And it cost only $5 compared to BB&B $20 exchange price. Even once BB&B is in stock again, I'm seriously thinking about using Wagner from now on. BB&B has more convenient hours, but Wagner is so much cheaper.

These guys are the F'n best. They offer a wide range of gases and different sized containers, welding accessories, etc. It seems to me that everyone working the front of house knows what they're talking about; I never leave with a question unanswered. The prices are awesome, and if you're doing a lot of commercial business, they'll beat any contract out there. Give these guys a ring this summer for some BBQ propane!

Amazing company, great customer service, great prices! I'm so glad that we work with you guys. And when I was in a bind they expedited shipping for me. Thank you for being awesome to work with!

Wagner is THE BEST! These guys really know what is going on! Amazingly helpful and always attentive. Awesome pricing on steel too! Cant say enough good things. Been going there for 13 years now!

Really impressed with the great customer service and unbeatable prices. Friendly, helpful staff. Swapped my old Amerigas bottles, now I'm a Wagner customer for life!

Very friendly and helpful staff! Every time I've gone in there to fill up my bbq propane tank they make the annoying process simple and fast.

Great place to buy propane. Far less expensive than swapping tanks at the hardware store. Helpful and professional staff

Great place. It is that old school quality and service. Good guys.
