If you searched for welding supplies in Santa Ana, CA, it helps to know upfront that Pen Manufacturing does not sell welding equipment or consumables to the public. Pen Manufacturing is a contract manufacturer providing custom welding services and metal fabrication to OEMs, engineers, and procurement teams across Santa Ana and the surrounding Orange County region from its Anaheim location, which has served the area since 1982. Pen Manufacturing is AS9100D and ISO 9001 certified and ITAR registered, supporting welding, metal fabrication, CNC machining, sheet metal fabrication, and finishing under one roof.

Pen Manufacturing does not operate as a welding supply retailer selling rods, wire, gas, or equipment. Pen Manufacturing is a custom welding and fabrication company that uses its own in-house welding equipment and materials to build parts and assemblies to a customer's drawings and specifications.

At our Anaheim facility, certified welders build structural assemblies, enclosures, and custom parts to your drawings in aluminum, stainless steel, and carbon steel. This is the core welding service Santa Ana OEMs use Pen Manufacturing for, rather than a supply purchase.
