12 gauge is slightly less than 1/8″ thick. Scenario One:Īll your welding is expected to take place indoors on clean metals 24 to 12 gauge thick.

Therefore, a portable 115v machine looks attractive and is worth looking into. You should ask yourself, what is the thickness range of the metals you will be welding? This will help determine if a 115v will be adequate for building your projects and making repairs.Įvery home will have several 115v outlets to plug a machine into. MIG vs Flux Core Welding Should I Use Gas or Flux Core when Welding? Selecting a machine that can perform both MIG and Flux Core welding is ideal to give you more versatility for your welding. It can handle a little debris on the surfaces to be welded, whereas GMAW needs the welding surfaces to be very clean. However, welding outside is not an issue with FCAW, and penetration rates are typically better. It also leaves a coating of slag on the finished weld that must be chipped off. The wire is hollow and contains flux powder to shield the weld from atmospheric contamination instead of gas.įCAW is not as good as GMAW at welding very thin materials as it tends to burn through easier. What is FCAW Welding?įCAW which is short for Flux Core Arc Welding is done with the same wire machine as GMAW but doesn’t use gas to shield the weld. GMAW also welds thin metals with less burn-through compared to FCAW. Compared to FCAW the welds will be more visually appealing and have no slag to chip off. This is because the shield gas tends to blow away before it can do its job. GMAW is not good for welding outside or in drafty conditions. To break it down further, it is welding with solid wire using an inert gas to shield the weld from atmospheric contamination. GMAW, which is short for Gas Metal Arc Welding is better known as MIG or Metal Inert Gas welding. We will only be dealing with the two associated with wire welding for this article. I’m not convinced they are helpful some may find them confusing initially.īut, they are inescapable in the welding world. School is still out for me regarding the acronyms applied to the various welding methods designated by the American Welding Society.
