and as a workshop installation, for jointing operations pipe-to-pipe, but
also for processing tees and elbows (see also the first paragraphs of Sect. 4.5
for more detailed information on this).
It has basically three functions:
• Controlling the welding process
• Monitoring all the relevant parameters during the welding process
• Generating a log protocol/report of the welding process

3.2 Control Panel
Emergency Stop Switch on the Control Unit
An Emergency Stop switch is provided on the control unit to abort
