Can You Weld Aluminum With A Mig Welder

Use an aluminum feeding kit to feed the electrodes and soft aluminum wire.
Apply the push method and fix wire feed issues as well. The contact tips need holes which are large enough to enter and small enough to offer electrical contact. The simplest way to explain this is that in order to increase heat to weld aluminum with a mig welder is to either increase amperage or use a welding machine with a bigger transformer. Material thicknesses of aluminum that can be mig welded are 14 gauge and heavier.
Yes you can weld aluminum with a mig welder. A 115 volt welder can handle aluminum up to an eighth of an inch thick 3 mm with adequate preheating and a 230 volt machine can weld aluminum that s up to a quarter of an inch thick 6 mm. You ll also want to keep the weld lead and liner as straight as possible to avoid the wire from kinking as it is very fragile. To mig weld aluminum thinner than 14 gauge 074 inch it may be necessary to use specialized pulsed mig or ac tig welding equipment.
This video will explain how to mig wire weld aluminum. The minimum aluminum thickness you should attempt is roughly 14 ga. You should adjust the settings and use wires with low crack sensitivity to minimize porosity cracking and other defects. Weld training mig welding aluminum.

A welder with a bigger transformer means you are going to spend more money. That along with a cylinder of 100 argon welding gas and a small spool of solid aluminum wire is an efficient and reliable method. If your welder isn t spool gun ready or you just want to save some money try mig welding aluminum without a spool gun. Aluminum is a tricky metal to weld with a mig welder because it takes more heat than mild steel usually in the range of 21 to 24 volts.
When you are choosing a shielding gas consider 100 argon as the best known option for mig welding of aluminum. To do this you will need to loosen spring tension to avoid the wire from snapping as it pulls through the feed rollers. To perform correctly without being distorted keep in mind the following features. You could install a spool gun on a compatible welder.
