Read more →MIG Welding Machines MIG welding machines are easy to use. Almost anyone can buy a MIG welding machine and be welding just minutes after plugging in the machine. Because of this, MIG welding machines have become very popular in recent years. MIG welding machines have come a long way since the 1980′s, due to technological advancements and inventions designed to

Read more →Choosing between a TIG welding machine and MIG welding machine MIG welding machines can make quick work of those around the house projects. With a basic configuration you have your MIG welding machine set up with “gasless” filler material commonly known as “Flux Core”. It welds ok, but you find that if you want “clean” results you need a bottle of Argon/Co2
Read more →MIG Welding Procedures. (1) The welding procedures for MIG welding are similar to those for other arc welding processes. Adequate fixturing and clamping of the work are required with adequate accessibility for the welding gun. Fixturing must hold the work rigid to minimize distortion from welding. It should be designed for easy loading and unloading. Good connection of the work
Read more →MIG Welding Process Principles. (1) Arc power and polarity. (a) The vast majority of MIG welding applications require the use of direct current reverse polarity (electrode positive). This type of electrical connection yields a stable arc, smooth metal transfer, relatively low spatter loss, and good weld bead characteristics for the entire range of welding currents used. Direct current straight polarity
Read more →MIG Welding Advantages (1) The major advantage of MIG welding is that high quality welds can be produced much faster than with SMAW or TIG welding. (2) Since a flux is not used in MIG welding, there is no chance for the entrapment of slag in the weld metal. (3) The gas shield protects the arc so that there is

Gas metal arc welding equipment consists of a welding gun, a power supply, a shielding gas supply, and a wire-drive system which pulls the wire electrode from a spool and pushes it through a welding gun.
