208 Flux Core (Gasless MIG) Welders Starting at $307.62

Flux-cored arc welding (FCAW) utilizes a continuously fed, hollow electrode filled with flux to create a shielding gas and slag layer protecting the weld pool during fusion. Compared to gas metal arc welding (GMAW/MIG), FCAW offers greater portability due to its self-shielding option and can achieve faster weld deposition rates.

Flux Cored Wire for Outdoor Applications

Welders from professional to hobbyist have been restrained from welding dirty and/or rusty materials, and from performing outside. This is no longer the case with the latest innovation in welding, particularly MIG welding. With the addition of Flux Cored wire; which is wire that has been hallowed out and filled with a powered Flux material and activated when coming into contact with the arc releasing a vapor that shields the welding pool of molten metal from the environment. Air causes a weld to become weak if this welding pool is not protected from said environment, and with Flux Cored wire this pool is protected by the vapor and a residue from the weld called slag. This byproduct covers and further helps to reinforce the weld making the end result very unsightly if the excess is not chipped away.

The sheer ability to use these machines outside on almost all materials makes them an invaluable machine to have in any workshop and/or jobsite. The Welders Supply Company sells all the materials you will need to maintain and perfect your weld.

All the welding equipment you’ll ever need for any welding applications sold here at affordable rates!
