NOTICE
• The ABICUT 155 cutting torch may only be operated by qualified
personnel (in Germany, see TRBS 1203).
• Please consult the operating instructions for the welding components,
such as the welding power source and the robot control unit.
• Check the actual gas flow on the measuring instruments or by closing
and opening the corresponding gas outlet openings on the torch.
• All necessary parameters (such as the cutting current, soft start,
compressed air, etc.) must be set on the power source in accordance with
the cutting operation.
