To MIG weld aluminum thinner than 14 gauge 074 inch it may be necessary to use specialized pulsed MIG or AC TIG welding equipment.

How to weld aluminum with a mig welder. The recommended electrode angle of travel is 5 to 15 degrees. What Youll Need to Weld Aluminum. Use DC reverse polarity the electrode will be positive while the base plate is negative.

Lets run through how you can stick weld aluminum. Hold your spool gun tip at an angle of 10 to 15 degrees from straight up. The spool gun will keep the aluminum from getting stuck inside.

Pure Argon gas is needed to weld Aluminum with a Mig welder. Tips for MIG welding. Aluminum should be thoroughly cleaned prior to welding including the removal of any lubricants from the material.

If the angle falls within this range it will be much easier to control the molten pool. Prepare your push-pull wire feed Clean your aluminum remove any oxide and file the edges that will be joined Avoid pulling while weldinginstead push at a. 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 successfully weld aluminum youll need a spool gun. In the forehand technique used for MIG welding aluminum the electrode will be pointed in the direction of travel. They have a special liner throughout the wire feed system which allows the use of aluminum welding wire in a MIG machine.

Otherwise it can burn through the metal. The MIG welding I am going to describe in this instructable is for steel which uses a copper colored wire. The tank is either 100 Argon or a mixture.

It is safe to keep the flow rate 20 to 30 cubic feet per hour. Achieve the Best Quality When MIG Welding Aluminum. Anything thinner than 18-gauge aluminum would require a TIG welder.

Can MIG welders weld aluminum. The process will require more heat than mild steel which is the most common metal used in MIG welding jobs. First of all when welding thinner sheets of aluminum make sure that the MIG welde r is not using too much power.
