Contact Information

Ingels Engineering Inc. provides products and services to Orthodontists, Orthodontist Industry Suppliers, medical firms, as well as scientific and emerging technology companies in the United States and Canada.

We are a family owned and operated business and we specialize in excellent customer service.

We manufacture a wide range of welding electrodes for 3M Unitek Welders model #'s1050, 1071, 1082 and similar welders in the industry. In some instances we are able to repair the welders, the cables and or the on/off switches. Repairs of welders often requires the Doctor to mail their machines to our Duarte location for the needed repairs, installation of replacement parts or maintenance cleanings.
