Tips for Choosing the Right Contact Tip | Bernard

However, when wire is fed from a drum (e.g. those 500 pounds and larger) and/or when using solid wire, an undersized contact tip may improve welding performance. Because wire from a drum tends to have less cast, it feeds through the contact tip with less or no contact — having a smaller bore exerts more pressure on the wire, creating greater electric conductivity.

What Is A Wire Welder? - MakeMoneyWelding

A wire welder, also known as a MIG welder or a flux core welder, is a semi-automated welding process. In fact, the simple welding process that a wire welder provides makes it the perfect welder for beginners. A wire welder has several components that you need to

Plant Engineering | Selecting a filler metal: Seven factors …

For instance, when welding on thin material, it is important that the arc characteristics are appropriate—a wire that provides deep penetration may cause the welding operator to burn through. On the other hand, if the part to be welded is thick and features a single "V" joint, a filler metal with better penetration characteristics allows for better tie-in at the root and sides.

How to Calculate MIG Wire Feed Speed | eHow

7/8/2020· Metal inert gas (MIG) welding machines automatically feed wire through the torch head of the welding gun to the weld site. This wire acts both as the electrode that arcs with the metal being welded to create the weld bead and as filler material to join the metal pieces.
