 Industrial Gases for Welding, Fabrication & Manufacturing

At Igo's Welding Supply Company, we manufacture and supply liquefied and compressed gases for the welding, manufacturing, and defense industries. As one of Massachusetts' last independently owned gas plants, we offer something that has become increasingly rare in our industry: local ownership, local decision-making, and our own routine delivery operation.

We take pride in providing some of the fastest, most dependable delivery service in the industry. Whether you're welding in a garage or running a full-scale production facility, we have the gas, equipment, and reliability to keep your operation moving.

A Partnership Built to Last

Boston Ship Repair has been working with Igo’s for years, and they have consistently provided premium services tailored to our needs. Their support extends across multiple aspects, including welding gases, purging gases, welding consumables, and new welding equipment procurement.

What sets Igo’s apart from larger corporate suppliers is their personalized, family-oriented approach. They go above and beyond to assist us, even in urgent situations. When our company was awarded a federal grant, Igo’s took the time to meet with us, carefully planning purchases to align with our production requirements and budget. They facilitated discussions with industry leaders such as Miller, Lincoln Electric, and Swift-Cut, ensuring we made informed decisions.

For the past year and a half, we have had a United States Naval ship drydocked at our facility, requiring a continuous and high-volume supply of mixed welding gases. Igo’s has met our demands every week without fail. Their commitment to service and reliability makes them the best local welding supply outfit in the Greater Boston area. We are fortunate to have a company like Igo’s as a trusted partner.

I had a great experience with Igo’s Welding Supply. I needed a set of tanks in a pinch, and within just a few hours they personally showed up in his pickup and delivered them right to me. That kind of old-fashioned, dependable service is hard to find these days. Super professional, friendly, and reliable — I’d give them a solid 10/10 for customer service. Highly recommend!
