Short stickout will cause burnback, where wire burns your welding gun consumables, clogs them, and interferes with wire feed. For strong flux core welds, stickout should be twice longer compared to MIG welding, approximately 3/4 inch. Stickout is referred to welding wire that extends from the tip of the contact tube. Once you've mounted the wire and adjusted the tension, you will need to leave a stickout. Low or high tension on welding wire can cause wire flattening, tangling, or birdnesing, which can impact your flux core weld's overall results and strength. Any good flux core welder, such as YesWelder MIG205 DS, will have a clearly marked tensioner as a part of a wire feed mechanism. Next, you will need to adjust the tension. You don't want to choose too high or lower than the required tensile strength wire. That's why you should check both typical tensile strength values on a data sheet and AWS classification for matching. The classification states the minimum tensile strength of the wire, e.g., 70.000 psi, but the filler metal manufacturer can meet or exceed it. To do so, you should always check the AWS flux core wire classification. Therefore, like with any welding process, you should match the strength of the flux core wire to the base metal. While penetration and amperage can somewhat be accredited for the weld strength, the vast majority of the physical characteristics rely on the flux core wires. While this can take some of your time, it is always better to clean the joint rather than rely on your flux-cored wire. Photo by easiest way to prevent porosity and slag inclusions in multiple passes is, you guessed it, to clean the weld joint with a wire brush or solvent prior to welding and chip the slag generated after the first pass. The porosity can interfere with the integrity of the weld, making it weaker, eventually developing the under bead cracking. In specific situations, porosity can occur inside the weld, which is even riskier since you cannot see it without weld testing. Once you start welding, the remaining oil, grease, paint, or dirt create tiny bubbles of nitrogen, hydrogen, or oxygen, referred to as porosity, that may appear on the surface of the weld. While these are often a solution in industrial applications, relying on flux core wire cannot replace proper weld joint cleaning and preparation. Flux-cored arc welding is considered a good option when working with dirty metal, as there are flux core or dual shielded flux-cored wires with de-oxidizers, similar to specific stick welding electrodes, that can quickly burn through any contaminants.
That takes in a lot of ground, and the Millermatic 180 covers it beautifully. It is employed in muffler shops, auto body shops, maintenance and repair garages, farms and ranches and where light metal fabrication is done. It’s all you’ll need at home to cover any repair that comes your way. This versatile welder is making a name for itself in multiple settings. The Millermatic 180 is backed by Miller’s TrueBlue 3-year warranty that covers parts and labor for 3 years. The welding range is 30 to 180 amps with variable settings to give you optimal power for each weld. Added to the 180 it gives you the functionality to weld aluminum from 18 gauge to ¼” thick.
MILLER FLUX CORE WELDERS SERIES
The Millermatic 180 is compatible with the Spoolmate 100 Series spool gun that makes welding aluminum easier than ever. Reset the unit at the torch, not the welder so you can get going again immediately. It will save your equipment and extend the life of the tip. The Tip Saver mode shuts down the welder when the tip shorts to the work. It includes spring-loaded tension arm with tension knob that is precisely calibrated for accuracy. The cast aluminum drive system is strong and durable, and it makes set up fast and easy. It is manufactured to withstand the rugged use welders receive on a daily basis. You’ll appreciate the quality build of the Millermatic 180.
