If the MMA welding process is selected, any cooling unit present is automatically de-
activated. It is not possible to switch it on.
IMPORTANT! Welding parameters that have been set on a control panel for a system
component (TR 2000 and TR 3000) may not be changed on the control panel of the
wire-feed unit under certain circumstances.
Use the wire speed adjuster to set the desired amperage.
The amperage value in A is shown in the digital display located above it.

Adjustments
while welding -
manual control
panel To obtain the best possible welding results, the arc-force dynamic parameter will some-
times need to be adjusted.
Set the required arc-force dynamic using the Dynamic buttons.
The value of the welding parameter is indicated by the LEDs located between the but-
tons.

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 electrically con-
ducting or earthed parts (e.g. the housing etc.)
Move the mains switch to the "I" position: all the indicators on the control panel light
up briefly
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 de-
activated. It is not possible to switch it on.
IMPORTANT! Welding parameters that have been set on a control panel for a system
component (TR 2000 and TR 3000) may not be changed on the control panel of the
wire-feed unit under certain circumstances.
Press the "Parameter selection" button to select the amperage parameter.
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 on and off again in the meantime.
Start welding
To display the actual welding current during welding:
-
Press the "Parameter selection" button to select the welding current parameter
