Maintenance and care
Repetition Test conforming to E VDE 0544-207, conforming to the German
Ordinance on Operational Safety

7.3.1
Test intervals and scope
A quarterly partial test and an annual extensive test are to be carried out. The extensive test must also be
carried out each time that repairs are made; in the case of heavy use, the period can be reduced (e.g. to
6 months when used at construction sites). In the extensive test, the machine must be opened and
cleaned according to the section entitled “Cleaning”. Only exterior cleaning is required for the partial test.

Documentation of the test
The result of the test must be documented to show the following clearly:
• Identify the tested machines,
• The date of the test
• The time of the next test and
• The
results
for later reference. The machine must be marked if the test is successful (e.g. with a test plate). This plate
must include the date of the next repetition test.
7.3.3
Visual inspection
Given below are the main points in the full test. The points to be tested with the machine open are not
required for the partial test.
1. Torch/stick electrode holder, welding current return lead clamp
2. Leads including plugs and couplings
3. Open plugs and couplings
4. Casing
5. Open casing
6. Special features of the welding power sources for plasma cutting
7. Operating, message, safety and adjustment devices
8. Other, general condition
7.3.4
Measurement of protective conductor resistance
Measure between the plug earthed contact and accessible metal parts, e.g. casing screws. During the
measurement, the connection lead must be moved across the entire length, but especially close to the
casing and plug inputs. This should uncover any interruptions in the protective conductor. All conductive
parts of the casing accessible from outside should also be tested to ensure a correct PE connection for
safety class I.
The resistance must not exceed a mains connection lead 0.3
Ω
up to 5m in length. For longer leads, the
permissible value increases by 0.1
Ω
per 7.5m of lead.
