THE HANDLER 125 EZ is a gasless flux-cored wire welder that is the first of its kind to feature a single control knob. That means it's fast to set up and easy to use. It automatically sets the correct voltage and amperage for the metal thickness selected. The unit has a maximum output of 125 amps, providing penetration and consistency on metal thicknesses ranging from 18 gauge to 3/16 in. using .030- to .035-in. flux-cored wire. It works well for outdoor work because no shielding gas is required. The small-sized unit is easy to pick up and move from the barn to the field, where it can be run off a portable generator.
