![]() ![]() The gun also uses diffused shielding gas (depending on the exact process) that helps to cover the weld zone and protect the molten metal from outside contaminants as it cools. On the other side of the circuit is the welding ground clamp. The lead is known as the electrode side of the circuit. ![]() A welding gun dispenses it at the pull of a trigger. This feeder holds a roll of welding wire, which functions as the filler metal for the weld. A wire feeder is attached to the machine. Aside from the wire, let’s take a look at what makes each of them unique.įCAW (flux-core arc welding) is a semi-automatic welding process that uses a constant voltage power source on a welder/inverter where the voltage is set on the machine and stays relatively consistent throughout the welding process. ![]() The primary difference is the wire that is used. They both use MIG equipment, and FCAW is sometimes called MIG flux-core. What is the primary difference between FCAW and MIG, also called GMAW (Gas Metal Arc Welding)? The difference is not in the equipment. However, they are distinct from each other. They are known as ‘semi-automatic’ processes and are very user-friendly processes overall. Both machines have a welding gun that strikes an arc with the pull of a trigger, feeds the filler metal from a roll of wire, and has adjustable parameters on the machine that stay relatively consistent. 0 FCAW vs MIG Welding: Differences & When to Use ThemĪside from automated welding processes, FCAW (flux-cored arc welding) and MIG (Metal Inert Gas) welding are the two most efficient welding processes out there. ![]()
