How To Weld Aluminium With Stick. The best method for maximum control over the aluminum welding process is AC alternating current TIG tungsten inert gas using a helium or argon mix. Then the best way to weld aluminum is using a MIG welder with a 100 argon gas shield.
The flux coating acts as a gaseous shield for the arc and the molten aluminum. For personal and small DIY projects Yes you can use a stick welder for joining aluminum. Use DC reverse polarity the electrode will be positive while the base plate is negative.
Firstly you need to get your flux-coated aluminum electrode ready prepare the base metal set the current and polarity on the welding machine right and start welding.
To weld aluminum with a stick welding machine you have to set the current on DCEP Electrode Positive Reverse Polarity. It will have a good penetration if you preheat the pieces and use the right electrode stick with the right coating. You will need a welder capable of at least 200 amps to successfully weld aluminum materials. For personal and small DIY projects Yes you can use a stick welder for joining aluminum.
