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.
How to MIG weld thick structural plates | Welpedia
Joining of thick material by using a welding process, always has been a major concern in fabriion industries. Here are some important points that are needed to know about the structural welding of thicker pates using Metal Inert Gas (MIG) process. Below listed
Welding Intro to Welding - University of Florida
Welding Intro to Welding • A weld is made when separate pieces of material to be joined coine and form one piece when heated to a temperature high enough to cause softening or melting. Filler material is typically added to strengthen the joint. permanently

Different types of welding and what they are used for
Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equipment.

Ca rbon Dioxide (CO2) is the most common of the reactive gases used in MIG welding and the only one that can be used in its pure form without the addition of an inert gas. CO2 is also the least expensive of the common shielding gases, making an attractive choice when material costs are the main priority.
