- Be conscious of possibility of hidden fire on covered objects or in another rooms due tu
heat transfer.
-
After finishing of welding check up the welding place for smoking parts or small fires
in the time interval up to 6 or 8 hours.

Handling the pressure bottles
You have to follow respective safety regulations (technical regulations for pressure gas TRG
253 and 303).
Due to high presure inside the bottles (up to 200 bar) it is necessary to secure them against
mechanical damage, overturning, downfall, heating up (max 50°C), against sunshine expo-
sure for a longer time and against strong frost.
- When the MIG/MAG device is being equipped with pressure bottle, you have to keep on
mind that the bottle could cause overturn of device on an uneven surface. To prevent
this kind of accident you should use an appropriate pressure bottles.
- Filling of the bottles is allowed only by specialized companies.

Protection against electrical accidents
It`s not allowed to carry the torch under armpit or to hold it in such way, that a current could
flow through human body. The device must be switched off during the longer breaks. When
the welding is finished and before moving, the device must be un-plugged from the power
supply. It is necessary to cut immediately off the power supply in a case of accident.
To prevent uncontrollable welding back current you have to connect the welding supply di-
rectly to the work piece by working clamp. The pipes, steel constructions etc... must not be
„electric conductors“ in any case, if they are not welded themselves.
Follow this instructions in any case:
The welding current must not have any conductive connection with protective or zero con-
ductor of the power supply network. Because the protective contact of power supply is con-
nected to welding device, you must not put the grounding clamp down on the welding device
body, when the device is connected to power supply network. The workpiece must be
insulated from power supply protective and zero conductor and from the grounding con-
ductor.
