Title: MIG welder
Description: Some tips on welding equipment, MIG and TIG welders, plasma cutters. A MIG welder uses a continually feeding spool of thin filler wire as an electrode fed by a wire feed gun to form an electric arc between a wire and the work-piece metal. This heats the work-piece metal and the electrode, causing them to melt and join together to create the weld. Mig welding can be either Gas or Gasless and each have benefits. Gasless welding is far more portable as there's no gas bottle to carry around, saves cost on having to buy gas bottles and regulators, is easier on positional welds and can penetrate deeper than Gas MIG although the welding wire for a gasless MIG is more expensive than a gasless MIG. Gas MIG welding produces much cleaner welds with no slag or spatter, is slightly better on thinner metals and the welding wire is cheaper than gasless MIG wire.

The position of the contact tip within the nozzle, referred to as the contact tip recess, is just as important. The correct contact recess position can reduce excessive spatter, porosity, insufficient penetration, and burn-through or warping on thinner materials. While the ideal contact tip recess position varies according to the application, a general rule of thumb is that as the current increases, the recess should also increase. Speedglass Welding Helmet. One of the most versatile welding helmets on the market right now, the 3M Speedglass gives you an additional hardhat component for protection from falling objects. It also features a model with an auto-dark visor and a quality built-in welding respirator. Speedglas helmet offers various viewport sizes and peripheral viewports that can be opened and closed at the user's discretion. Three sensors in the lens provide a rapid reaction time and reliable auto-darkening capability. The lens goes from clear to working dark in .1 milliseconds. Tig amp rating is up to 4 amps, which means that you will be able to weld or thin sheet metals like exhaust vents, aluminum and all sorts of professional micro-welding. The lens returns to full-clear with adjustable delay settings after the weld stops, allowing your eyes to adjust and metal to cool.
