Welding ImageForney Industries has welding and plasma cutting machines designed for the do-it-yourselfer, along with folks in the industrial market. Forney designs quality machines that serves both markets extremely well, and our warranty rate is less than 2%-- which is considered world class.

Forney offers all the accessories that a DIYer would need to operate our machines, including contact tips, magnets, scribes, carts, MIG wire, pliers, cold galvanizing compound, electrode holders, ground clamps and more.

We also offer a wide selection of stick electrodes, brazing rod and TIG filler metal. This offering fulfills DIY and most industrial requirements for MIG, ARC, TIG and brazing applications. 

Welding 

How does welding work? 

Welding is simply taking two or more base metals and joining them together. They can be joined by various methods, but various forms of ARC welding are the most common. Sometimes a filler metal is used, and sometimes welding is done without a filler metal.

How do I choose what welding process to use? 

When welding outdoors usually stick welding is used as the process. This is a more portable method, and you don't need to worry about the wind blowing the shielding gas away. Sometimes Flux-Core welding is used when outdoor welding because the shielding gas doesn't need to be moved around as much as other processes. 

If you have long welds to make indoors, the preferred method is usually MIG welding. Just make certain the base metals are fairly clean. 

If you need to weld on a lot of different base metals stick welding is usually favored. This method is quick and easy to change out the stick electrode and go from welding stainless steel, to mild steel, or whatever material you're working with. 

If you want to weld aluminum, you can choose MIG welding with a spool gun, or TIG welding. MIG welding is faster, but TIG welding can be more precise and provide higher quality welds. For more information on TIG welding aluminum, check out this blog. 

How do I choose a stick electrode?

Each stick electrode has certain characteristics that make it better for specific situations. 

For mild still and carbon steel, E6011 is a fairly common, deep penetrating rod that works well for most steel applications but may not provide the best-looking weld. E6013 is a rod designed for welding in almost any position and is easy to strike and maintain an arc. E7014 is an easy-to-strike rod and provides a nice looking weld, and is best for welding in a flat position. The E7014 electrode is also a great rod for beginners. The E7018 rod can provide very high-quality welds for more critical or structural welds, and is incredibly versatile. For more information on the E7018 electrode, check out this blog

What are the main types of ARC welding?

Stick (SMAW- Shielded Metal ARC Welding) is a flux-coated metal rod where the rod and flux are melted into a puddle by the heat of the ARC. The flux provides shielding from the atmosphere and also helps deal with contaminants. MIG (GMAW- Gas Metal ARC Welding) is a sold wire fed by a motor where a continuous ARC is made and the heat from the ARC melts the wire and forms a puddle. A shielding gas provides protection from the atmosphere. 

 


Flux-Core (FCAW- Flux-Core ARC Welding)
is similar to MIG welding, but the wire is a continuous wire tube with flux in the middle. The wire, flux melt and the flux provide the shielding from the atmosphere. 

TIG (GTAW- Gas Tungsten ARC Welding) is significantly different than other processes, as the ARC occurs between the base metal and tungsten electrode and filler metal is fed into the puddle by hand. A shielding gas provides protection from the atmosphere.
