Danger to life due to electric shock
Electric shock can result in fatal injuries.
● Before all repair, setup and maintenance work, disconnect the
welding laser system from the power supply by removing the
mains plug.
● Secure the welding laser system against unintentional
switching back on.
● In addition, trigger an Emergency Stop button.
● As the operating company, specify the type and scope of the required checks.
● Specify the intervals for the recurring checks so that the welding laser system can
be safely used until the next specified check.
Proven intervals for recurring checks for electrical working equipment
(stationary) are generally: every 4 years. The checks must take place in
accordance with the applicable electrical engineering regulations.
Furthermore, the reduction of the inspection interval for all portable
electrical devices to once per year is required.
● Immediately rectify loose connections and damaged cables.
● Categorically never work with equipment under voltage. Only in
exceptional cases with compelling reasons present is this allowed.
● As the operating company, record these compelling reasons in
writing before the start of work under voltage.
● Only carry out work on live components in accordance with national
requirements and procedures.
The work must only be carried out by skilled electricians or electrical
engineering instructed personnel who have received specialist training.
