| Description: | Several advices about welding equipment, MIG and TIG welders, plasma cutters. MIG welders use a wire welding electrode on a spool that is fed automatically at a constant pre-selected speed. The arc, created by an electrical current between the base metal and the wire, melts the wire and joins it with the base, producing a high-strength weld with great appearance and little need for cleaning. MIG welding is clean, easy and can be used on thin or thicker plate metals. Similar to MIG welding, flux-cored arc welding (FCAW)* is a wire-feed process but differs in that self-shielded flux-cored welding does not require a shielding gas. Instead, flux-cored wire is used to shield the arc from contamination. This is a simple, efficient and effective welding approach, especially when welding outdoors, in windy conditions or on dirty materials. The process is widely used in construction because of its high welding speed and portability. Best welding advices: Improper drive roll selection and tension setting can lead to poor wire feeding. Consider the size and type of wire being used and match it to the correct drive roll. Since flux-cored wire is softer, due to the flux inside and the tubular design, it requires a knurled drive roll that has teeth to grab the wire and to help push it through. However, knurled drive rolls should not be used with solid wire because the teeth will cause shavings to break off the wire, leading to clogs in the liner that create resistance as the wire feeds. In this case, use V-grove or U-groove drive rolls instead. Set the proper drive roll tension by releasing the drive rolls. Then increase the tension while feeding the wire into your gloved hand until the tension is one half-turn past wire slippage. Always keep the gun as straight as possible to avoid kinking in the cable that could lead to poor wire feeding. X- Mode is an unique trait of this welding helmet and Miller patented technology (that's why no one else can use it). You see when you strike an ark, 3 types of radiation are emitted. UV (as a bright light) Infrared (as heat) and Electromagnetic radiation. On all other welding helmets, sensors are triggered by IR radiation. Hence the flashing with a low amp, grinding problems, sun and etc. This Millers hood's sensors are triggered by a lower spectrum of electromagnetic radiation"X-rays". This means there will be no flashes, never. The ADF will go dark literally moments before the arc is struck. ADF won't lit up when grinding, and the sun will not be a problem and it will continuously detect the arc even if sensors are blocked. |
