Condition: like new (used), Year of construction: 2024, load capacity: 6,000 kg, workpiece weight (max.): 6,000 kg, Stierli- ROTATOR 600 / 6 to Ijdpfogqgb Usx Abvoth 360° turning device for fast and safe turning and rotating of beams, profiles and welding components. Use for welding, plastering, fast welding visual inspection, as assembly turning device etc.... Capacity: 6 tons Swing circle diameter: 600mm (e.g. beam HEB 600) Length of parts: freely selectable (stands are freely positionable by means of hand pallet truck) Adjustment of working height: Steplessly adjustable The Stierli rotator was developed to turn heavy and large loads such as beams and welded constructions quickly and safely without a crane. This saves you a lot of working time and increases productivity. This welding positioner or welding manipulator works as a lifting turning device with reliable chains. The turning device is not only used for beam welding, but other cross sections can also be turned with it, such as the use as a pipe turning device. Loading is impressively simple with the overhead crane, or by means of forklift loading. The rotator can be brought into position very easily with the hand pallet truck, whereby the distance between the uprights of this welding device is freely selectable.

Condition: used, functionality: fully functional, The Selco NEOMIG 242 is a classic, extremely robust MIG/MAG welding machine from the Italian premium manufacturer Selco (which was acquired by voestalpine Böhler Welding several years ago). Unlike modern, fully digital inverter machines, this is a stepped, electromechanical transformer system. This means that it is considerably heavier and larger than a modern compact inverter, but it is considered practically indestructible in metalworking shops and workshops, with an enormous service life and a very stable arc. Technical data at a glance Feature Value / Specification Welding process MIG/MAG (gas-shielded welding) Connection voltage 400 V (3-phase / three-phase) Welding current range 30 – 240 A Duty cycle 30% at 240 A60% at 170 A100% at 131 A Voltage levels Multi-stage, manually adjustable Wire feed Integrated, mechanical roller feed Max. power consumption approx. 8.3 kW Cooling Typically gas-cooled (standard hose package) Ijdpfszd S Ryox Abvoth Important features & practical advantages Classic transformer technology: Since no sensitive electronics are installed in the power unit, the NEOMIG 242 tolerates dust, metal grinding dirt and moisture much better than modern inverters. It also operates absolutely reliably under harsh conditions in the workshop or on-site. Excellent welding properties: Selco was known in the industry for its perfectly matched copper transformers and chokes. The system provides a very spatter-free, smooth and even arc in steel, stainless steel and also in thinner aluminum applications. Intuitive operation without unnecessary features: No complicated digital menus. You select the appropriate welding level, adjust the wire speed on the potentiometer and can start immediately. Using toggle switches, modes such as 2-cycle / 4-cycle (for long seams) as well as spot and interval welding can also be activated. Used market assessment: Since this series is no longer produced new, it is a real insider tip on the used market for workshops and ambitious DIY enthusiasts. Note: Sold without warranty or guarantee. We assume no liability for the operational functionality of the machine. The sale is made excluding any liability for material defects, to the extent permitted by law.
