Aluminum Pulse Mig Welding Settings Chart

Mig welding or metal inert gas is normally used for welding aluminum.
Aluminum pulse mig welding settings chart. In other words no matter how you set the controls the machine circuitry is rapidly making adjustments on the fly its not as simple as just setting voltage and wire speed. Gas entrapped in solidifying metal forms spherical or elongated pores in the weld. So if you are welding 12 gauge mild steel with a thickness of 0 100 you would set the machine at 100 amps. The settings needed to mig weld aluminum are pretty much the same for all positions.
Spray arc welding requires a constant current and constant voltage machine while pulse welding requires an inverter power supply. For pulse settings set pulse width 60 peak current 185 background current 75 hz 1 0. When welding mild steel a good rule of thumb is to set the amperage level at 1 amp for every 0 001 of thickness. For out of position mig welding pulse spray cannot be beat.
The angle at which the electrode leads the weld pool relative to the direction of travel. Good equipment makes mig welding easier while poor equipment can cost you dearly in frustration and weld quality. Mig welder settings charts guides and tables for steel stainless and aluminum lincoln mig welding electrode and gas selection chart settings. 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 welding pulse settings are pretty confusing and one of the reasons is that a lot of mig welding machines capable of pulse settings use what is called a synergic control. Lincoln mig welding aluminum setting chart aluminum mig welding settings. In most cases it will take 21 to 23 volts to get the arc to spray transfer. Productivity increases with improved deposition rates using ac aluminum pulse gmaw waveform technology are.
For pulse settings set pulse width 60 peak current 125 background current 50 hz 1 0 3 16 1 4 pre flow 1 sec hot start 20 amperage 185 post flow 8 0 sec. Over heating of aluminum. The welder you choose should use impulse welding or spray arc welding methods. Ac aluminum pulse gmaw brings features that cannot be realized with standard dc pulse mig welding.
If you re looking for a machine with multiple welding capabilities we recommend multiprocess welders like the multimatic 215 and multimatic 220 ac dc. Mig welders such as the millermatic 211 and millermatic 141 are ideal for the occasional welder. Gas metal arc welding including metal inert gas mig and metal active gas mag welding.
