Functional characteristics TIG welding 5.3.2 Optimising the ignition characteristics for pure tungsten electrodes The best ignition and stabilisation of the arc (DC, AC) and optimum spherical cup formation in the tungsten electrode depend on the electrode diameter being used. The set value should correspond to the diameter of the tungsten electrode. The value can of course be adjusted in line with different requirements.

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.

5.3.9 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.

DIN EN 61010-1 Appendix A – Measuring Circuit A1. You as the user are tasked with ensuring that your EWM machines conform to the standard IEC/DIN EN 60974-4 and are tested with the relevant test equipment and measuring devices given above.
Maintenance and testing Test 7.3.2 Scope of the test a) Visual inspection b) Electrical test: measurement of • open circuit voltage • insulation resistance, or alternatively • leakage currents • protective conductor resistance c) Functional test d) Documentation 7.3.3 Visual inspection The key areas in the test are: 1.
Note: Even if the leakage current measurement according to the standard is only an alternative to the insulation resistance measurement, EWM recommends always performing both measurements, especially following repair work. The leakage current is based for the greater part on a physical effect other than the insulation resistance.
