Programmable shielding gas post-flooding

In order to eliminate the oxidation of the welded joint directly after it has been welded, the times during which the shielding gas ist still conducted on the welded joint following the welding can be individually set.

In the lower power range, which depends upon high stability, traditional lasers are inclinined toward a low „pulse to pulse stability“ and thus to a non-uniform welding result. The Pulse Width Modulation (PWM) gives a vastly more fine and stable coordination, as the internal energy supply here works in the area of the optimal output.

Free pulse shaping enables the setting and saving of all possible variations in the pulse process. Materials with different thermal coefficients of expansion thus show a clearly better welding behaviour - your laser´s area of application thus expands.

This allows you to see into deep crevices or holes which would be in darkness if lateral illumination were used. The illumination comes alongside the optical beam and always illuminates accurately from above.

On-axis shielding gas supply

A reliable on-axis shielding gas supply enables perfect welding even with highly-sensitive materials, such as titanium, for example.

The welded joint is always flooded with shielding gas under 90 degrees. This prevents the sort of shadow effects and swirling which occurs when a lateral gas supply is used.

Specially developed turning units increase the user value of your workstation. They incorporate all functions of CAN-Step control, available at the touch of a button, including pulse synchronization and „Teach in“ programming.

Additional features: • Swivel-mounted • Free implementation up to Ø40 mm • different chuck types, chucking range up to Ø 160 mm.

Large display with backlighting

The large backlit display provides the user with a direct view of all the important operating parameters. Adjustment limits are visualized.

The adjustment of the parameters themselves takes place via the work chamber´s control elements.
