The machine must not be operated in the open air and must only be set up and operated on a suitable, stable and level base! • The operator must ensure that the ground is non-slip and level, and provide sufficient lighting for the place of work.
3.1.1.1 activArc 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.

Example: 7mm gas nozzle corresponds to 7l/min gas flow. Incorrect shielding gas setting! If the shielding gas setting is too low or too high, this can introduce air to the weld pool and may cause pores to form.

Design and function TIG welding 5.8.7 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 5.8.4 Expert menu (TIG) chapter"...
Design and function TIG welding 5.8.8 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). 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 50
Design and function TIG welding 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. The frequency can be infinitely adjusted from 50 Hz to 15 kHz and the pulse balance from 1-99 %.
5.8.9 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.
