When to Use Pulse for TIG Welding

TIG welding with pulsing is most commonly used on thin metals such as aluminum, but can also be used on copper and various steels. Pulsing can be set by the foot pedal or as a setting on the TIG welder, but when should I use pulsing? There are some very specific applications for pulsing with a TIG welder, and sometimes it can come in handy to get the job done better. Here are some TIG welding applications that use pulsing.

 

When you need a neat weld seam

Pulsed welds are an easy way to create smooth, clean welds for TIG welding applications. Putting yourself in a steady pulsing rhythm is the ideal way to keep moving the puddle forward or moving the cup along the weld seam.

TIG welding is most often used when errors are minimal and the metal is exceptionally thin. By pulsing along the weld seam, you can adjust the amount of filler metal added, distribute it evenly, and create an aesthetically pleasing weld seam.
