Safety
The effective measures avoid the problem of EMC::
Power source:
- Even though the power source connection meet rules, we still need to take additional measure to remove
the electromagnetic interference (eg: Use the right power filter).
Length of welding cable:
- Keep the cable length as short as possible.
- Lay out the unit cables next to each other and place them with sufficient distance to other cables.
Ground connection of work-piece.
Shielding, when necessary:
- Shield the ambient equipment
- Shield the entire welding device

Safety labels on the plasma cutter
NOTE:
Damaged or missing safety symbols on the plasma cutter can lead to incorrect operation resulting in
personal injury and damage to property. The safety symbols attached to the machine must not be
removed. Damaged safety symbols must be replaced immediately.
Observe the following:
The instructions on the safety label on the unit must be followed under all circumstances. If the safety labels
fade or become damaged during the life of the appliance, new labels must be attached immediately.
From the time when the signs are not immediately recognisable and comprehensible at first sight, the unit
must be taken out of operation until the new signs are attached.
