Design and function TIG welding 5.7.10 Pulses, function sequences NOTE The function sequences in pulses basically behave in the same way as in standard welding, but during the main current phase there is a continual switching back and forth between the pulse and pause currents at the relevant times. The pulse function can also be deactivated if necessary during the upslope and downslope phases (see chapter "Advanced settings"). -
Page 39: 5.7.11 Tig Activarc Welding
TIG welding 5.7.11 TIG activArc welding The EWM activArc process, thanks to the highly dynamic controller system, ensures that the power supplied is kept virtually constant in the event of changes in the distance between the welding torch and the weld pool, e.g. during manual welding. Voltage losses as a result of a shortening of the distance between the torch and molten pool are compensated by a current rise (ampere per volt - A/V), and vice versa. -
