Pulse Mig Welding Aluminum Settings

Over 0 100 traditional mig spray transfer is beneficial in contrast to mig welding steels the pulsed mig process provides real welding benefits.

Pulse mig welding aluminum settings.

Pulsed mig is beneficial on all aluminum applications. A pulse spray welder is used for welding of thin aluminum 18 gauge or less. In most cases. You should first check your mig welder s manual or if there is one the settings chart on your mig welder itself.

Finding the settings for aluminum welding on your mig. Aluminum should be thoroughly cleaned prior to welding including the removal of any lubricants from the material. In most cases it will take 21 to 23 volts to get the arc to spray transfer. This may seem like common sense but many fabricators get hung up on purchase price vs.

The settings needed to mig weld aluminum are pretty much the same for all positions. Aluminum mig welding settings. 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. 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.

To mig weld aluminum thinner than 14 gauge 074 inch it may be necessary to use specialized pulsed mig or ac tig welding equipment. Ac aluminum pulse gmaw brings features that cannot be realized with standard dc pulse mig welding. Built in mig and pulsed mig programs automatically set the optimal parameters for a variety of wires and the system simplified the welding operation by using synergic pulsed mig controls and profile pulse. The viscosity is beneficial when using spray or pulsed transfer for all position welds pulsed mig ideal for applications 0 040 to 0 100.

Productivity increases with improved deposition rates using ac aluminum pulse gmaw waveform technology are. Matched with d 74 mpa plus dual wire feeders the system allows welders to quickly switch between two metals typically aluminum and then a second wire such as stainless or silicon bronze. Oxide removal should be done after degreasing using a stainless wire brush. When mig welding aluminum obtaining good quality and productivity depends on using the right welding process and system.
