Overview plus

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 flux core welder is lightweight, convenient 23 pounds, and easy to carry. You can easily store and transport this little flux core welder because of its small footprint.

Flux Core MIG Welder Mobility

The best thing about a 110v MIG welder is that you 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.

    How to Use plus

    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.

    Selector Switches plus

    Selector Switches

    1. Abnormal Indicator: Lights up if there is a problem with the welder operation
    2. Current/Wire Speed Adjustment Knob: Controls the speed that the welding wire feeds out of the MIG gun and the output amperage of the welder.
    3. Voltage Adjustment Knob: Provides adjustment and control of the welding voltage under MIG mode. It has not effect under MMA mode.
    4. MIG/MMA Selector: Provides selection of MIG or MMA (Stick) welding modes. Selecting MIG position provides for MIG welding function. Selecting MMA position provides for Stick welding function.
    5. 2T/4T Selector: Use this to set the Gun Trigger operation to either 2T or 4T mode.
    6. 2T (2 Touch) Mode: 1. Squeeze the trigger to start the welding current. 2. Release the trigger to stop the welding current.
    7. 4T (4 Touch) Mode: 1. Squeeze the trigger to start welding. 2 Release the trigger during welding. 3. Squeeze and release the trigger to shut welding current off.
    8. Quick Wire Feed Functions: While not welding, the wire feed will go slow at first. Hold the trigger down for 5 seconds for the machine to enter into wire quick feed mode. The wire speed cannot be adjusted under quick feed mode. Wire speed can only be adjusted when welding with arc.
