Aluminum Mig Welding Settings Chart

How to adjust a mig welder voltage settings.

Aluminum mig welding settings chart.

Browse suggested weld parameter settings for stick welding tig welding mig solid wire welding and mig flux core welding. Your machine s electrodes are responsible for leading the electricity flow from the metal into the welding handle. Material thicknesses of aluminum that can be mig welded are 14 gauge and heavier. Here s why when mig welding aluminum you use the same gun angle and gas flow rate 20 30 cfh.

Good equipment makes mig welding easier while poor equipment can cost you dearly in frustration and weld quality. In most cases a mig welder will utilize dc direct current. Lincoln mig welding aluminum setting chart aluminum mig welding settings. Mig welders such as the millermatic 211 and millermatic 141 are ideal for the occasional welder.

In most cases it will take 21 to 23 volts to get the arc to spray transfer. The lincoln 140 setting chart yellow column. Lincoln suggest you use their super glaze aluminum mig wire. If you re looking for a machine with multiple welding capabilities we recommend multiprocess welders like the multimatic 215 and multimatic 220 ac dc.

To start the pictures above and below are the manufacturer s recommended lincoln welders and miller welding equipment voltage wire feed speed settings and gas recommendations. Mig welder settings charts guides and tables for steel stainless and aluminum lincoln mig welding electrode and gas selection chart settings. Again you could buy the 0 035 inch diameter aluminum wire you wanted. If welding out of position you will want the wire feed speed fast enough to keep the weld full of metal at a.

When welding mild steel a good rule of thumb is to set the amperage level at 1 amp for every 0 001 of thickness. The settings needed to mig weld aluminum are pretty much the same for all positions. You ll need a magnum 100sg spool gun. The output capacity of your welder determines the thickness you can weld.

Metal thickness amperage settings. If you haven t yet mastered mig welding mild steel then you probably need to do that before you start aluminum welding with the gmaw mig process. Therefore the voltage setting will decide how deep the welding torch penetrates through the material and also the quality of the welding joints. To mig weld aluminum thinner than 14 gauge 074 inch it may be necessary to use specialized pulsed mig or ac tig welding equipment.

However that s pretty much where the similarities end. The final column on your settings chart are your settings for mig welding aluminum.
