  • Page 37: Ac Welding

    Functional characteristics TIG welding 5.1.4 AC welding The welding of aluminium and aluminium alloys is made possible by the periodic change of polarity on the tungsten electrode. The negative pole (negative half-wave) of the tungsten electrode determines the penetration characteris- tics and has a lower electrode load compared to the positive half-wave.

  • Page 38: Automatic Ac Frequency

    Functional characteristics TIG welding 5.1.4.2 Automatic AC frequency The machine control takes over the regulation or setting of the alternating current frequency depending on the set main current. The lower the welding current, the higher the frequency and vice versa. This achieves a concentrated, directionally stable arc when welding currents are low.

  • Page 39: Ac Balance (Optimise Cleaning Effect And Penetration Characteristics)

    Functional characteristics TIG welding 5.1.4.3 AC balance (optimise cleaning effect and penetration characteristics) It is important to choose the right time relationship (balance) between the positive phase (cleaning effect, balled end size) and the negative phase (penetration depth). This may differ from the factory setting de- pending on the material and task.

  • Page 40: Ac Amplitude Balance

    Functional characteristics TIG welding 5.1.4.5 AC amplitude balance As with AC balance, durations (balance) for positive phase and negative phase are set for AC amplitude balance. The balance changes in terms of the current amplitude. Figure 5-12 Increasing the current amplitude in the positive half-wave facilitates the cleaning effect and the cracking of the oxide layer.

  • Page 41: Synchronous Welding (Ac)

    Wiring differences in the supply network are also compensated. Optimum phase compensation immedi- ately shows better welding results. Two EWM power sources can be synchronised using the phase shift parameter in steps of 60° (0°, 60°, 120°, 180°, 240° and 300°).

  • Page 50: Tig Activarc Welding

    5.1.8 TIG activArc welding The EWM activArc process, thanks to the highly dynamic controller system, ensures that the power sup- plied 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.

    Functional characteristics TIG welding 5.1.12.2 Responsiveness This function controls the responsiveness of the welding current during the main current phase. The user can choose between linear and logarithmic responsiveness (factory setting). The logarithmic set- ting is especially suited for welding with low current, for example for thin sheet metal. This method ena- bles better dosing of the welding current.
