1.4.1 Glossary:
1. Pre-gas flow: Time elapse of gas flow before welding
2. Arc-start: Min current of start arc
3.Up-slope: Time elapse of welding current slopes up
4.Constant current: welding current on output constant current
5.Oxide clean ratio: time ratio of output clean current
While in AC TIG, regulate clean width and penetration to obtain optimum welding
quality.
Figure 12: Illustration for Oxide clean ratio
6. AC Bias: Ratio of clean current dividing by welding current.
By adjusting the parameter, as to adjusting clean current result in reasonable oxide clean effect.
Suggestion: At the same clean effect, reduce clean ratio and increase AC bias to obtain deeper
penetration, higher productivity and prolong tungsten electrode lifespan.
7. AC frequency: Frequency of output AC
8. Peak: Peak value of output pulse
9. Pulse ratio: Time ratio between length of peak value current and length of whole single pulse
applied in pulse TIG, can be easily used for controlling penetration in all-position or thin sheet
welding.
10. Pulse frequency: Output pulse frequency
11.Base current: Arc maintenance current of output pulse
