[MW:22195] Pulsed Mode GTAW HEAT INPUT calculations

How i can measure travelling speed and current in pulsed mode GTAW.
Because there are always 2 values of these parameters 1 for high pulse(HP) and  1 for low pulse(L).
i actually want to calculate heat input for this.so any guidance will be appreciated.
i.e. my data is
HP current 112 A
LP current 56 A
HP time 0.31 sec
LP time 0.31 sec
HP travelling speed 1 mm/min
LP travelling speed 150 mm/min
also can anyone tell me how can i find arc voltage value in machine data because i am using ORBIMAT 300 CA model of orbital welding machine and i can't find arc voltage value.thanx in advance
For more details i have attached a document with this Post.
