Guide to TIG Welding Basics - MillerWelds
2022年10月11日 · While DC TIG welding, a lack of shielding gas, loose cable or torch connections, or an incomplete weld circuit can all cause arc starting problems. Also be sure to use the right tungsten size and type — choose a ceriated (gray) or lanthanated (blue) tungsten. In addition, check to make sure the power supply switch positions are correct.
Best Practices For Proper Shielding Gas in TIG Welding - Miller
2017年12月12日 · The optimal gas flow rate for TIG welding varies by the combination of consumables and atmospheric conditions. GTAW flow rates are typically between 10 and 35 cubic feet per hour (cfh). When the shielding gas exits the nozzle, it has a different velocity than that of the atmospheric gases surrounding it. The different velocity and density ...
Remove stick electrode from holder or cut off welding wire at contact tip when not in use. Wear body protection made from durable, flame−resistant material (leather, heavy cotton, wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
How to Solve 10 Common TIG Welding Problems [Guide] - Miller
2020年4月3日 · The TIG process is complex, and it is undisputedly the most difficult process to learn. Follow these basic tips to prevent common TIG welding problems. 1. Poor gas coverage. The weld here shows contamination caused by lack of shielding gas. This can happen when the shielding gas is not turned on, there is either too little or too much gas ...

What Gas Should You Use for MIG Welding in DIY Applications?
2022年11月22日 · The most common gas used for MIG welding aluminum is 100% argon. This gas allows you to get into a spray transfer or pulsed spray transfer mode easily for aluminum due to its low ionization value. Another benefit of 100% argon gas is that it can also be used for TIG welding aluminum.
How a TIG Welder Works and When to TIG Weld | MillerWelds
2021年9月1日 · TIG stands for tungsten inert gas and is technically called gas tungsten arc welding (GTAW). The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. An inert gas, typically argon, protects and cools the tungsten and weld puddle. TIG welding is similar to oxy-acetylene welding in that you use a filler ...

Use water-cooled torch when welding with more than 200 amps. Butt Weld (V-Groove) Bevel must have 60 degree included angle. 3/16 Root face. AC TIG is generally used to weld aluminum and magnesium materials. For the best appearance, highest quality and leak free welds on aluminum, AC TIG welding is the process of choice.
TIG Welding Aluminum for Beginners | MillerWelds
2009年8月1日 · Keep a close distance from the tungsten to the workpiece, typically equal to the diameter of the tungsten up to about 1/4 inch. If you pull the tungsten too far away from the workpiece, the arc spreads out too wide and overheats the piece, causing loss of puddle control.
