Top 3 Advantages of Using Pulsed-MIG Welders
When MIG welding was first invented, it used a constant voltage source of electricity for the arc. While this method is still used today, the invention of pulsed MIG (or MIG pulse) welders has allowed welders to realize several advantages over conventional MIG welders, several are listed below:
Pulsed MIG can be used to weld thin materials. Conventional MIG welders run at a constant amperage whereas pulsed GMAW welding runs a peak and background amperage. The constant switching between these two amperages enables the welder to put out a lower overall heat input into the material. This helps prevent blowouts on thin materials.
- There is less spatter than conventional MIG welders. Pulsed MIG welders use peak electrical currents to cleanly burn the wire off at a high amperage. It also employs a lower background welding amperage immediately after the peak electrical current to prevent the interaction of the electrical arc and the wire from becoming unstable. This ultimately results in a reduced amount of spatter.
- MIG pulse welding is excellent for out of position welding. At the same voltage and wire feed settings, conventional MIG tends to have a weld puddle that is larger and more fluid than that of pulsed. MIG pulse welding has a more controllable puddle that prevents it from falling out when gravity is a concern during out-of-position welding. Furthermore, the reduced amount of spatter that can be achieved with this method makes it safer for the welder to perform the out-of-position operation.
