![]() ![]() 035 wire on metals within this thickness range, I suggest you step up to a higher capacity 230v machine. Scenario Two:Īll of your welding is expected to take place indoors on clean metals 1/8″ to 1/4″ thick.įor MIG welding with gas and. The 115v will be the best for you in this scenario economically. The smaller wire will make it easier to weld the 24 gauge material.030 wire will have a higher deposition rate and could also be used. If all of your planned projects and repairs fall within the parameters of this scenario, I suggest a 115v MIG welder like Hobart 50059 using gas with. 12 gauge is a little less than 1/8″ thick. Scenario One:Īll of 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 indeed 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 is going to have several 115v outlets to plug a machine into. Should I Use Gas or Flux Core when 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 has a tendency 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 will have no slag to chip off. This is because the shield gas has a tendency 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 totally convinced they are helpful and some may find them confusing at first.īut, they are inescapable in the welding world. School is still out for me when it comes to the acronyms applied to the various welding methods designated by the American Welding Society.
