INTRODUCTION
Note!
This product is solely intended for arc welding.
LTR 160/200 are rectifiers based on inverter technology and designed for TIG welding and
welding with coated electrodes. They are available in two versions, one with a central socket
and one with an OKC socket for connecting a TIG torch.
The machines are supplied complete with 5 metre mains cable, 5 metre return cable, gas hose
and hose clamps.
Versions with a central socket are also supplied with a protective handle to protect the
connections from strokes.
An optional top handle can be fitted to the machine for winding up cables and to protect the

Two different trolleys are available to facilitate transport with a gas cylinder and cooling unit.
INSTALLATION
WARNING
This product is intended for industrial use. In a domestic environment it may cause
radio interference. It is the user’s responsibility to take adequate precautions.
LTR 160/200 are equipped with mains voltage compensation, which means that a
¦
10 %
variation in the mains voltage only results in a
¦
0.2 % variation in the welding current.
To reduce the voltage drop when using a long cable it can be advisable to select a heavier
cable cross section.
1. Place the equipment in a suitable place and make sure the machine is not covered or
set--up so that cooling is prevented.
2. Make sure the machine is connected to the correct mains voltage.
Earth according to applicable directives.
3. Connect the shielding gas.
4. Connect the TIG torch and the return cable or the MMA welding cables.
The machine is now ready for welding.
