Safety
Preparation Move the mains switch to the "O" position
Disconnect the mains plug
Plug the grounding (earthing) cable into the (-) or (+) current socket (depending upon
which type of electrode is to be used) and latch it by turning it clockwise
Use the other end of the grounding (earthing) cable to establish a connection to the
workpiece
Plug the electrode holder cable bayonet plug into the free current socket with the op-
posite polarity, according to the type of electrode, and turn it clockwise to latch it in
place
Plug in the mains plug
MMA welding
Move the mains switch to the "I" position: all the indicators on the control panel will
briefly light up
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.
Press the "Parameter selection" button to select the amperage parameter.
Use the adjusting dial to set the desired amperage.
The amperage value is displayed in the left-hand digital display.
All welding parameter set values 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.
WARNING! Operating the equipment incorrectly can cause serious injury and
damage. Do not use the functions described until you have thoroughly read and
understood the following documents:
-
these operating instructions
- all the operating instructions for the system components, especially the safe-
ty rules
WARNING! An electric shock can be fatal. If the machine is plugged into the
mains electricity supply during installation, there is a high risk of very serious in-
jury and damage. Do not carry out any work on the device unless
-
the mains switch is in the "O" position,
- the device is unplugged from the mains.
IMPORTANT! Check the rod electrode packaging to determine whether the rod electrodes
are for (+) or (-) 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 electrically conducting
or earthed parts (e.g. the housing, etc.).
IMPORTANT! Under certain circumstances, welding parameters that have been set
on a system component control panel (TR 2000 and TR 3000) may not be changed
on the control panel of the power source.
