With the Handler® 190 (500554), weld as thin as 24 gauge up to 5/16" in a single pass with a broad output range of 25–190 amps. Easily weld thicker materials with multiple passes. Quick and easy setup with Quick Select™ drive rolls which offer three grooves—two for different sizes of solid wire and a third for flux-cored wire. Easy to set and adjust for different materials and thicknesses — features seven output voltage settings for finer control, less spatter and cleaner welds. The Handler 190 also features a direct plug-in for the optional SpoolRunner 100 spool gun. The use of a spool gun reduces wire feed problems associated with soft aluminum wire and other mild or stainless steel wires.
