Manual metal arc
welding
CAUTION!
Risk of injury and damage from electric shock.
As soon as the mains switch is in the "I" position, the rod electrode in the electrode
holder is LIVE. Make sure that the rod electrode does not touch any persons or electric-
ally conducting or earthed parts (e.g. the housing etc.).
1
Move the mains switch to the "I" position: all the indicators on the control panel light
up briefly
2
Press the Process button to select the MMA welding process:
The welding voltage is connected to the welding socket with a 3-second time lag.
If the MMA welding process is selected, any cooling unit present is automatically
deactivated. It is not possible to switch it on.
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.
3
Press the Parameter selection button. The LED indicator on the button must light up.
4
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.
5
Start welding
NOTE!
The power source has a pulsating open circuit voltage.
When the MMA welding process is selected, the right hand digital display shows an aver-
age welding voltage value of 40 V before welding begins (open circuit). The following
maximum welding voltages are available for the welding start and the welding process to
ensure optimum ignition properties:
â–¶
TPS 2700 ... 50 V
â–¶
TS 4000 / 5000, TPS 3200 / 4000 / 5000 ... 70 V
Corrections dur-
ing welding
In order to obtain the best possible welding results, the following parameter can be
corrected 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
