Our compact, affordable MIG160 160-Amp Flux Core MIG Welder gives you enough on-demand power to weld up to 1/4 in. mild steel both MIG, flux-cored, and stick welding thick on household current. PrimeWeld builds them to last, and this 110v MIG welder is equally at home in your garage or at the worksite.

This gasless flux core MIG welder is lightweight and portable, weighing just 23 pounds. You can easily store and transport this little flux core welder because of its small footprint.

A Portable Flux Core MIG Welder

The MIG160 160-Amp Flux Core MIG Welder can weld anywhere there’s standard household current available. The PrimeWeld MIG160 also runs as a flux core welder when you don’t have or don’t want to run shielding gas. Not everyone has the room to store a giant cylinder of CO2, a cart to secure it, or a way to transport it conveniently.

An additional advantage that a flux core MIG welder has over gas MIG: it performs better when you have to weld outside with a breeze. MIG shielding gas tends to blow away from the arc in those conditions. The flux core welder’s wire is hollow and filled with flux material. The flux evaporates into the gas as the wire melts, enveloping the weld to keep oxygen out.

Versatility and Durability in One Welder

Every PrimeWeld MIG160 is built from the ground up to take workshop conditions in stride. We know you need your tools to last and keep up with your work pace. PrimeWeld believes our MIG160 160-Amp Flux Core MIG Welder should work as hard as you do.

Great for both hobby and professional welders. It’s highly portable to move around any sized job and designed to ensure reliability, stability, and ease of use. Great to weld magnesium, cast iron, mild steel, copper and copper alloys, stainless steel, and more.

How to Do a Basic Weld

1. Press and hold the Trigger and contact the area to be welded with electrode wire to ignite arc.
2. For a narrow weld, you can usually draw the wire in a steady, straight line. This is called a stringer bead.
3. For a wider weld, draw the wire back and forth across the joint. This is called a weave bead and takes practice to perform properly.
4. Direct the welding wire straight into the joint. This gives an angel of 90° (straight up and down) for butt (end to end) welds and an angle of 45° for fillet (T-shaped) welds.
5. For MIG welding using solid wire and shielding gas, the end of the MIG Gun should be tilted so that wire is angled anywhere in-between straight on and 15° away from the direction you are welding. The amount of tilt is called the push angle.
6. When using flux-cored wire without shielding gas, the end of the MIG Gun should be tilted so that wire is angled anywhere in-between straight on and 15° in the direction you are welding. The amount of tilt is called the drag angle.
7. The Contact Tip should remain with 1/2" of the work surface. This distance is called stick out.
8. After welding the test weld on a piece of scrap for a few seconds, stop, and check your progress. Clean, then compare your your weld's appearance with the user manual linked at right.
