Pulse TIG settings using a

The video below shows 7 tips for TIG welding aluminum

There is no one size fits all pulse setting that works for every application.

The following pulse settings work well on a 16ga stainless outside corner joint if you are trying to limit distortion and discoloration

1 pulse per second

5% background

30% pulse duty

Chill bars can help a lot too when it comes to limiting distortion.

I like the digital readout feature on the primeweld tig 325x. It makes setting pulse rates easier.

The 3 main settings for pulse tig are

1. pulses per second (pps)
2. background current ( a percentage of peak pulse)
3. pulse duty ( sometimes called peak pulse or pulse width which is the percentage of time the peak pulse is on)

Pulse tig can be helpful but is not always a benefit in manual welding due to the weldor making sub conscious adjustments.

That said there are several applications where pulse settings can help control heat and distortion.
