Press the Parameter selection button. The LED indicator on the button must light up.
Use the adjusting dial to set the desired amperage.
The amperage value is shown in the left-hand digital display.
All welding parameter set values that have been set using the adjusting dial remain
stored until the next time they are changed. This applies even if the power source is
switched off and on again in the meantime.

Press the Parameter selection button to select the parameter you wish to correct
Use the adjusting dial to set the selected parameter to the desired value. The param-
eter value is displayed in the digital display located above it.
HotStart function To obtain optimum welding results, it will sometimes be necessary to adjust the HotStart
function.
Benefits
- Improved ignition, even when using electrodes with poor ignition properties
- Better fusion of the base material during start-up phase, meaning fewer cold-shut de-
fects
- Largely prevents slag inclusions
See the "Setup menu: level 2" section for details on setting the available welding parame-
ters.
NOTE! Parameters that have been set on a system component control panel
(e.g. wire feed unit or remote control) might not be able to be changed on the
power source control panel.
NOTE! The power source has a pulsating open circuit voltage. When the MMA
welding process is selected, the right hand digital display shows an average weld-
ing voltage value of 40 V before welding begins (open circuit). The following max-
imum welding voltages are available for the welding start and the welding process
to ensure optimum ignition properties:
- TPS 2700 ... 50 V
- TS 4000 / 5000, TPS 3200 / 4000 / 5000 ... 70 V

In order to obtain the best possible welding results, the following parameter can be cor-
rected in certain circumstances:
Arc-force dynamic
to influence the short-circuiting dynamic at the instant of droplet transfer
0 soft, low-spatter arc
100 harder, more stable arc
