Wagner Welding provides high quality acetylene gas for your welding, metal fabrication, and medical needs. Acetylene gas has many uses in a variety of industries. Its high burning temperature makes acetylene an ideal gas for welders and metal fabricators. The medical and science fields use acetylene gas for various instruments, and many manufacturers use acetylene for the production of glasses, paints, resins, and acrylic fibers.
As a stable, non-reactive gas, argon offers various benefits to many industries. Welders use argon as a shielding gas for GMWA (gas metal arc welding) and GTAW (gas tungsten arc welding). Argon is also an important component in the production of several household products, including incandescent light bulbs and solar panels, and acts as a preservative in numerous foods and products.
At Wagner Welding Supply, we supply carbon dioxide in high pressure gas cylinders or liquid CO2 dewars in various sizes. For the past seventy years, we have supported many local industries and organizations-both large and small-in the Longmont/Denver Metro area.

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.

I buy propane, $16 for a 20lb fill but okay only for what you get, so half full, you pay half. You can get SodaSteram bottles for $5 plus tax. $5 for what costs $20 we oth shipping from others.
great store,… highly recommended.
on Nextdoor people gave me a hard time because Sams (membership required) is about $1 cheaper for propane.
SPEND THE F'ING DOLLAR TO SUPPORT LOCAL BUSINESS.

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.

Be careful when you have propane tanks filled if you got a new tank you soon have an old beat up and rusty tank! Not to mention the general manager had enough decency to hang up during our conversation when I questioned him about it!

I worked for this company. Do not be fooled, safety is not their priority! I drove for them transporting dangerous gases and was very concerned when the tires on my truck were becoming bald. So I asked the owner Dennis and Russ the shop manager to replace them. After viewing the tires, they both determined I was safe to continue driving on them. I then turned to the owners wife Danine to help make this dangerous situation better. She was willing to go against the owner and manager and sent me to get tires. Thank goodness she did besause the tire shop had determined that both front tires had broken

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.

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!
