When Joe Stangl started Unitec in 1969, he had one goal in mind – to provide the best quality welding products and solutions to his customers in an efficient, friendly manner.

In 2015, Joe, and his son Richard are doing it again with Josef Gas. We are truly THE hands on industrial gas supplier. Joe and Richard’s relationships with customers and suppliers alike span decades and at Josef Gas we are proud to continue those relationships by being a fully Authorized Distributor for the top brands in welding such as Lincoln, Miller, Victor, and ESAB, J Walter, Fibremetal, 3M, Harris, and Avesta among others.


Our new home is a 3 acre facility at 201 Basaltic Rd in Concord. It is here where our industrial gases, propane and welding equipment are all processed. It’s also the place where we maintain our 15 delivery trucks, 20,000 industrial gas cylinders and the largest single storage propane tank facility in the GTA.


Find the latest welding equipment on display in our modern showroom.  From abrasives to cutting equipment, regulators, welding machines and helmets along with all of the accessories!
