Transport and installation
The machines may only be transported and operated in an upright position.
Before carrying away or moving, pull out mains plug and place on the machine.
When the power source is moved and positioned, it is only tilt resistant up to an angle of 10° (as
specified in EN 60974-A2). The following points should be noted here in particular:
•
Add-on parts are to be distributed evenly according to their weight and suitably secured during
transport.
•
Obstacles on the ground can cause additional tilting.
•
Damaged fixed castors and guide castors should be replaced immediately.
•
For machines with a rotating external wire feed unit (e.g. DRIVE 4L), make sure that it is fixed
securely and cannot rotate in an uncontrolled manner.
Secure the gas cylinder!
• Place shielding gas cylinders in the holders provided for them and secure with safety chains.
• Take care when handling cylinders; do not throw or heat, guard against them toppling over.
• When moving by crane, take off the gas cylinder from the welding machine.
2.2.1
Ambient conditions
This machine must not be operated in any area where any risk of explosion exists.
The following conditions must be observed during operation:
Temperature range of the ambient air
• During welding: -10°C to +40°C *),
• For transport and storage:
-25°C to +55°C *)
*) Using the appropriate coolant.
Relative air humidity
• up to 50% at 40°C
• up to 90% at 20°C
The ambient air must be free of unusual amounts of dust, acids, corrosive gases or substances, etc.,
assuming these are not produced by the welding process.
Examples of unusual operating conditions:
• unusual
corrosive
smoke,
• vapour,
• excessive
oil
vapour,
• unusual vibrations or jolts,
• excessive quantities of dust such as grinding dust etc.,
• severe weather conditions,
• unusual conditions near the coast or on board ship.
When setting up the machine, ensure a free inlet and outlet of air.
The machine is tested to protection class IP23, i.e.:
•
Protection against penetration of solid foreign bodies
∅
> 12mm,
• Protection against water spray up to an angle of 60° to the vertical.
