Hi GJ,
I hope these explinations are of some help.
1. Initial slope, time 0-2s. This is for the time it takes to get up to the welding amps that have been set.
2. Peak current, 20-200A. This is for setting the upper limit of power for the weld.
3. Background Current. This is the low-level current needed to maintain the arc.
4. Final slope, time 0-5s. This is the time it takes to stop the arc by reducing the amps down.
5. Arc force. This is more for Stick Welding ( MMA ).
6. Pulse frequency, 1-70Hz. This shapes the weld bead by narrowing the arc cone with increased frequency.
7. AC balance, 10% - 90%. This controls the amount of positive or negative electrode time on the tungsten.
8. Clean width, 20% - 80%. This controls the cleaning of the area that is being welding.( Removal of the oxide )
9. Post flow, time:2-10s. This is the time gas flows at the end of a weld to keep oxygen out of the weld puddle.
