6.1
General
Warning – Risk from electrical current!
Follow the safety instructions on the opening pages entitled “For your safety”.
Connection and welding leads (e.g. electrode holder, welding torch, workpiece lead, interfaces)
may only be connected when the machine is switched off.
Re-fit protective caps onto sockets and cable plugs when not in use!
6.2
Area of application – proper usage
These welding machines are only suitable for:
• MMA direct current welding for rutile and basic electrodes.
• TIG direct current and alternating current welding with HF ignition or liftarc.
• TIG DC: Unalloyed, low-alloy and high-alloy steels, copper, nickel-based alloys and special metals.
• TIG AC/DC: Aluminium and aluminium alloys.
Any other use is regarded as "improper" and no liability is assumed for any damage arising therefrom.
We can only guarantee smooth and trouble-free operation of the machines when used in
conjunction with the welding torches and accessories from our range.
6.3
Installation
Ensure that the machine is set up in a stable position and is appropriately secured.
With modular systems (power source, transport vehicle, cooling module), observe the operating
instructions for the relevant machine.
Set up the machine so that there is sufficient room to adjust the operating elements.
6.4
Mains connection
The operating voltage shown on the rating plate must match the mains voltage.
For mains fuse protection, please refer to the “Technical Data” chapter.
The correct mains plug must be attached to the mains supply lead on the machine.
The connection must be made by a qualified electrician in compliance with the relevant local laws
and regulations.
The phase sequence for three-phase machines is optional and has no effect on the fans direction
of rotation.
• Insert mains plug of the switched-off machine into the appropriate socket.
6.5
Machine cooling
To obtain an optimal duty cycle from the power components, the following precautions should be
observed:
•
Ensure that the working area is adequately ventilated,
•
Do not obstruct the air inlets and outlets of the machine,
•
Do not allow metal parts, dust or other objects to get into the machine.
6.6
Workpiece lead, general
Remove paint, rust and dirt from clamping and welding areas with a wire brush. The workpiece
clamp must be mounted near the welding point and must be fixed in such a way that it cannot
come loose of its own accord.
Structural parts, pipes, rails etc. may not be used as return leads for the welding current unless
they are part of the actual workpiece.
Correct current connection must be ensured when using welding benches and appliances.
