Welding Wisdom for Professionals and Beginners Alike.

TIG welding 1-inch aluminum needs a strong machine, ideally 250 amps or more. Preheat the aluminum to help the weld. Use AC TIG with a gas mixture of 75% helium…

AC balance in TIG welding aluminum is the setting that controls the mix of cleaning action and penetration during the weld. A 50-50 AC balance often works best. Modern TIG…

Use a TIG welder with an AC frequency of 150 to 250 Hz for thin aluminum materials. This frequency ensures accurate weld placement without burning through. For thicker aluminum, use…

TIG welding of 3/16 aluminum involves using AC current and argon gas. Begin with a short preflow for comfort. Adjust amperage with a foot pedal. Ensure good ventilation to control…

For aluminum GTAW, set 1 amp per 0.001 inches of thickness. Preheat to 200°F. For 3/16 inch aluminum, use 150 amps and adjust the foot pedal as the puddle forms….

Use easy methods to join aluminum without welding. First, clean the aluminum with a wire brush. Next, cut and chamfer the edges. Use a propane torch to heat the aluminum…

Tungsten may melt when welding aluminum because of wrong current settings or insufficient gas flow. Use electrode negative (DCEP) for AC welding. Choose the right tungsten type and size; too…

To weld aluminum with a propane torch, clean the surfaces with a stainless wire brush to remove aluminum oxide. Use brazing rods that melt below aluminum’s melting temperature of 1200°F….

For aluminum welding, use a Green Tip (Pure Tungsten) for optimal AC performance. This type offers effective conductivity. Alternatively, choose a Blue Tip (2% Lanthanated) for versatility and better arc…
