Welding Basics : Techniques for Tig, Mig & Arc Welds

The fabrication process joining materials together is known commonly as welding, and it involves a welding power supply combined with metals melting (and melting pools) to create fusion. Arc welding is a common welding process which uses a power supply to keep an electric arc between electrodes and base materials to melt metals. Currents and voltage are used to maintain the energy needed for melting the materials. Undoubtedly, the art of welding can be very dangerous, and special equipment and protective gear is required to keep welders safe and guarded from potential burns. Once a welder has learned how to safeguard his or herself against the dangers, and knows the essentials of using the machinery, they can begin welding under the supervision of a professional. It is not wise to operate any machinery unfamiliar to you unless you're being instructed by a professional or an instructor. Always use caution when using machinery and lasers.

In this free video clip series, our expert will demonstrate the ways in which you prepare a welding machine, manage voltage and energy levels as well as techniques for the different modes of operation and equipment. Learn how to use the weld supplies, tig, wig and arc welds and more. Techniques such as the Push and Pull are explained and demonstrated, as well as basic information such as setting up the welding machine and an introduction to the gases used for welding are included.
