  • Page 39: Spotarc

    Design and function TIG welding 5.6.10.2 SpotArc The TIG SpotArc function is activated with the pulse variant automated frequencies by default, because this combination produces the most effective results. The user can of course combine the function with other pulse variants depending on the selected welding process. Pulse time (t1) and pulse break time (t2) can be set independently, but the spot time (tP) should be much greater than the pulse time in order to achieve an appropriate result.

  • Page 43: Pulses, Function Sequences

    Design and function TIG welding 5.6.11 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 44: Pulse Variants

    Design and function TIG welding 5.6.12 Pulse variants NOTE The machines have an integrated pulse device. With pulses, the machine switches back and forth between the pulse current (main current) and pause current (secondary current). 5.6.12.1 Pulses (thermal pulses) With thermal pulses, the pulse and pause times (frequency up to 200 Hz) and the pulse edges (ts1 and ts2) are entered in seconds on the control.

  • Page 45: Khz Pulses (Metallurgic Pulses)

    Design and function TIG welding 5.6.12.2 KHz pulses (metallurgic pulses) The kHz pulses (metallurgic pulses) use the plasma pressure produced at high currents (arc pressure) which is used to achieve a constricted arc with concentrated heat feeding.

  • Page 47: Tig Activarc Welding

    TIG welding 5.6.13 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.
