Welding Wisdom for Professionals and Beginners Alike.

To weld aluminum with a spool gun, adjust the wire feed and voltage settings. Use 4043 or 5356 wire for strength. Preheat the aluminum to avoid cold lap at the…

To weld aluminum with a spool gun, set the polarity to Direct Current Electrode Negative (DCEN). This method helps penetrate the material effectively. The spool gun simplifies feeding the wire….

To weld aluminum corner joints effectively, set up the joint accurately. Use a 1.5-2mm arc length and adjust the machine to 150A. For inside and outside corners, ensure proper filler…

To weld copper wire to aluminum, use a TIG welder for optimal results. Start by pre-cleaning both metals to remove oxidation. Then, heat the copper and aluminum until the solder…

For MIG welding aluminum, set argon flow rates to 40-60 cf/hr. For mixtures of helium and argon, choose flow rates of 50-100 cf/hr. Do not use an argon flowmeter for…

To weld aluminum tubing, use MIG or TIG welding. For MIG, employ 100% argon as the shielding gas. Preheat the area to around 1200°F to help melt the metal. Clean…

Welding plugs for aluminum tubes are internal end fittings made from aluminum alloy. They are designed for Schedule 80 tubing. Clean aluminum surfaces and use TIG welding techniques for best…

To prepare polished aluminum for welding, first degrease the surfaces with a solvent. Then, clean and dry the welding joint using cheesecloth or paper towels. These materials effectively absorb oils…

When welding pot metal aluminum, use low-temperature settings to prevent damage. Weld in intervals of five to ten seconds to allow cooling. Stop immediately if the metal starts to flow…
