As a result, many automotive enthusiasts who specialize in bodywork or those who work with thinner applications prefer solid wire in their operations. 030-inch solid wire set at 18-19 volts with 160-170 amps and using 75 percent argon and 25 percent carbon dioxide shielding gas will usually produce little spatter, create a smaller heat heat-affected area and reduce chances of burn-through. For example, a short short-circuit transfer with. When working on materials less than 3/16-inch thick down to thin sheet metal (24 gauge), solid wire will produce a clean looking weld. Many welders believe that weld appearance is an important factor. What to consider when choosing solid or flux-cored wire Appearance

As a result, self-shielding flux-cored wire is more portable because it does not require an external gas tank. As a result, it creates a shelf to hold the molten pool when welding overhead or vertically up. Self-shielding flux-cored wire does not require external shielding gas because the weld pool is protected by gas generated when flux from the wire is burned. Gas-shielded flux-cored wires have a flux coating that solidifies more quickly than the molten weld material. Consider using gas-shielded flux-cored wires when welding on thicker metals or in out-of-position applications. Gas-shielded flux-cored wires require external shielding gas, and the slag is easy to remove. There are two types of flux-cored wires - gas-shielded and self-shielded. While using solid wire outdoors, welders should use caution and prevent any wind from blowing the shielding gas coverage away from the welding arc. The most common shielding gas combination is 75 percent argon and 25 percent carbon dioxide. The shielding gas protects the molten weld pool from contaminants present in the surrounding atmosphere. Mild steel solid wires are usually plated with copper to prevent oxidation, aid in electrical conductivity and help increase the life of the welding contact tip. MIG power sources use a continuous solid wire electrode for filler metal and require a shielding gas delivered from a pressurized gas bottle.

This article will help the novice or occasional welders - such as farmers, ranchers, motorsports enthusiasts and home hobbyists - understand the basics of solid and flux-cored wire and how to maximize the advantages of each. There is no one-size-fits-all welding solution, and all of the above variables will affect the welder’s decision to use solid or flux-cored wire. To achieve the best results, consider the following factors: thickness of the material, proper shielding gas, wire feed speed and voltage settings, location of the jobsite, and weld appearance. MIG welding and flux-cored welding possess different characteristics that welders must evaluate when selecting which process to use for welding applications.
