Equipment Details


Aluminum can be a challenging material for manufacturing, but not every manufacturer faces the same challenges. Lincoln Electric offers feature-packed solutions tailored to a user’s specific needs, and include the essential attributes you should expect for success in welding aluminum.



The New Industry Standard

Built on a simple platform, the AlumaFab® multi-process system is easy to set up and easy to operate, yet rugged enough for any heavy-duty aluminum application. AlumaFab leverages key technologies available in all of our industrial aluminum platforms to overcome common welding issues like erratic feeding, arc instability and soot.


Improving the Basics

With the AlumaFab, we have taken the most commonly used waveforms for Aluminum and simplified them so you don’t have to worry about using the correct settings. Just dial in and weld. For those of you who just want a simple, the AlumaFab system has the standard CV Pulse and CV Spray modes to satisfy your most essential Aluminum welding needs. CC Pulse (Constant Current Pulse) improves upon the standard pulse waveform to provide better stability while whipping or shuffling the weld puddle with a smooth arc, while still maintaining excellent starts and stops.
