7. Adjust Pulse freq. to desired setting (how often pulse happens)
8. Press the Tig torch switch to start welding
The benefits of pulse welding is the ability to control the weld pool and amount of heat absorbed by
work resulting in a smaller heat affected zone which results in fewer deformations and reduced
chance of cracking. There are no set rules for pulse welding as this is down to personal choice by
the welder.
