TIME 5000 Digital and CMT control panels.
The inputs required for MMA welding are described by reference to the Comfort control
panel.
Preparation Move the mains switch to the "O" position
Disconnect the mains plug
Remove the MIG/MAG welding torch
Plug the grounding (earthing) cable into either the (-) or the (+) current socket, depend-
ing on the type of electrode, and latch it in firmly
Use the other end of the grounding (earthing) cable to establish a connection to the

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 power source is connected to the
mains electricity supply during installation, there is a high risk of very serious in-
jury and damage. Before carrying out any work on the device make sure that:
- the power source mains switch is in the "O" position
- the power source is unplugged from the mains
NOTE! Check the rod electrode packaging to determine whether the rod
electrodes are for (+) or (-) welding.
