To find the right amperage for TIG welding aluminum, use this rule of thumb: set 1 ampere for every 1/1000 inch of aluminum thickness. For instance, if the aluminum is 1/4 inch thick, adjust the welder to 250 amperes. This approach ensures good penetration and high-quality welds. Additionally, factors such as joint design, welding speed, … Read more

TIG welding parameters for aluminum depend on material thickness and position. For 1/4 inch thickness: use 260 amps in flat position, 235 amps in horizontal and vertical positions, and 240 amps for overhead. Adjust AC amperage according to your specific welding setup to ensure strong and quality welds. When preparing for TIG welding aluminum, select … Read more

To weld aluminum with a Miller 30A, set the gun angle slightly forward, tilting back 10-15 degrees. Use speed control at level 2, voltage around 22V, and an argon flow rate of 30 CFH. For 1/16” thick material, aim for 90-100 amps, 15-20V, and a wire feed speed of 260-300 IPM. Always follow safety precautions. … Read more

Advanced TIG welding of aluminum needs careful techniques. Use AC for effective results. Follow the amperage rule: apply 1 amp per thousandth of thickness.
