Arco Welding Supply
ARCO Welding Supply Company has been the leading distributor of welding equipment and welding supplies from the top manufacturers in the industry. Since we first opened our doors in 1950, we've been successfully serving professional welders throughout Massachusetts, southern New Hampshire and Rhode Island.

Whether you're a novice or seasoned welder, you can expect nothing less than quality customer service from us. With an extensive inventory carried in our Malden, MA warehouse, combined with our partnership with the Independent Welding Distributors Cooperative (Weldmark), we can guarantee our customers the highest quality welding equipment, welding supplies, and industrial gases when they need it.
Services
We are a factory authorized service repair center for all major welding equipment brands including Miller, Lincoln, Hobart, Hypertherm, and Weldmark to name a few. We offer diagnostic and repairs to your existing equipment either on-site or in-house performed by fully trained and experienced technicians.
At ARCO Welding Supply we provide more than an extensive inventory of welding products from leading manufacturers - we also stock a large selection of industrial gases so we can quickly service our professional welding customers with all the welding supplies they'll need. We offer high purity gases, specialty gases, and shielding gases that can be custom-mixed.
Our reputation as a leading New England welding supply distributor was not by accident. At ARCO Welding Supply, our goal has been to continually ensure that our warehouses are stocked with all the welding equipment, supplies, and safety gear needed to support every type of welding application - and provide a level of service that our customers have come to expect from us.
Eliminate Overwelding - Make sure welds are properly sized by following what is called out on the print. Don't have prints? Develop them! The savings can be huge. Reduce the amount of reinforcement - Multiple pass welds on a groove joint typically end up with a certain amount of reinforcement. The goal is to be just above flush to prevent under fill.
We offer a wide selection of welding equipment rentals from major brands at affordable rates. We can deliver to your job site, or convenient pick up at our Malden Ma facility. Terms of Rental: 1 Day = 8 hours, 1 Week = 7 days or 40 hours, 1 Month = 30 days or 160 hours. Rental rate: All rental rates are based on a minimum of 1 day with weekly and monthly rental rates offered.

Hours on the website do NOT match the actual hours. Website says they are open on Saturday but they are not. I really enjoyed wasting my time on a Saturday morning because they can't be bothered to update their website (but they redid the hours on the glass door at the shop ... Which one takes more time and reaches more people?)

When I came here to refill a huge propane tank I except that someone will help me to take out it from the trunk of my truck. It didn’t happen thought. There was two guys and one who hold a can of Red Bull in his hand told me “you should do it”. Ok, I did it. But when I asked to help me put heavy refilled tank back to the trunk other guy acted like he is doing a huge favor to me.
I guess I will go to more customer friendly business next time.

Incredible service. The knowledge of the employees alone makes a trip here vastly superior to ordering off of Amazon.

Can never find my account or my contact information when I'm waiting on an order or if the order is delayed no heads up but the info magically appears when it's time to pay the bill?
