ESAB Fabricator 141i Welder #W1003141

ESAB Fabricator 141i multiprocess welderThe ESAB Fabricator 141i Welder is a portable 3-in-1 welding system for MIG, TIG and Stick welding. It will output 140 amps for MIG and TIG welding, and 90 amps for Stick welding projects. This welder is primarily for small scale DIY projects. It operates on a standard 115-volt input power and comes complete with a 15 amp or 20 amp adapter.

Weighing just 33 pounds, it's easy to move around but packs enough punch to get the job done without weighing a pound more than it needs to. Not only is the Fabricator 141i lightweight and easy to use, it has well-thought out features like overload protection, a flow gauge regulator, and a fan on the welder that keeps dust and dirt from being sucked into the machine. The Fabricator 141i is a great tool for the price, especially with the included Victor Argon Regulator and 10-foot hose. 

Welders Supply Company has the Fabricator 141i at the lowest price possible, and all orders over $300 ship FREE to anywhere in the lower 48 states.
