Design and function

MMA welding

5.4 MMA welding
Risk from electrical current!
If welding is carried out alternately using different methods and if a welding torch and
an electrode holder remain connected to the machine, the open-circuit/welding voltage
is applied simultaneously on all cables.
• The torch and the electrode holder should therefore always be placed on an insulated
surface before starting work and during breaks.
For connection description, see the relevant "Power source" operating instructions.
5.4.1

Welding task selection

For selection of the welding task and for general operation see the relevant Control operating instructions.
5.5

Remote control

The remote controls are operated via the 19-pole remote control connection socket (analogue) or
the 7-pole remote control connection socket (digital), depending on the model.
Read and observe the documentation to all system and accessory components!
5.6

Access control

To protect against unauthorised or unintentional adjustment of the welding parameters on the machine,
the control input can be locked with the aid of a key switch.
In key switch position 1 all functions and parameters can be set without restriction.
In key switch position 0 the following functions and parameters cannot be changed:
• No adjustment of the operating point (welding performance) in programs 1–15.
• No change of welding or operating mode in programs 1–15.
• The welding parameters can be displayed but not changed in the control's function sequence.
• No welding task switching (JOB block operation P16 possible).
• No change of special parameters (except P10). Restart required.
5.7

Interfaces for automation

No improper repairs and modifications!
To prevent injuries and damage to the machine, only competent personnel (authorised
service personnel) are allowed to repair or modify the machine.
Unauthorised manipulations will invalidate the warranty!
• Instruct competent personnel (authorised service personnel) to repair the machine.
Accessory components and the power source itself can be damaged by incorrect connection!
• Only insert and lock accessory components into the relevant connection socket when the
machine is switched off.
• Comprehensive descriptions can be found in the operating instructions for the relevant ac-
cessory components.
• Accessory components are detected automatically after the power source is switched on.
