Year of construction: 2023, condition: used, functionality: fully functional, machine/vehicle number: 2331 280, We sell a used Bolte Pro I-2200 stud welding unit with microprocessor control. MFG 2023, serial number: 2331 280 The trolley version of the PRO-I 2200, with two large, extremely robust wheels and a telescopic handle, is ideal for mobile use on construction sites. Technical features and advantages: Excellent welding quality – modern inverter technology ensures very precise control and high reproducibility of the welding process Very high arc stability – also in cases of short welding times and low welding currents Powerful – high welding current of 1050 A for a maximum welding diameter of 13 mm Fast welding sequences through innovative cooling concept Ideal for mobile use – considerably less weight than conventional stud welding units Robust construction for use in harsh environments Low energy consumption due to high efficiency Easy operation via a very robust rotary pressure switch Microprocessor control All functions and parameters are displayed on a large display (display contrast is adjustable) Welding program library Welding program storage – 59 Welding range: Ø 2-22 mm Welding current: 100-2100 A Welding method: studs with ceramic rings or shielding gas and short-cycle stud welding with or without shielding gas Welded materials: steel, stainless steel, aluminum Voltage: 320-495 V, 32 A, 50/60 Hz Power source: transformer/rectifier Welding time: 1-1500 ms, continuously adjustable Protection class: IP23 Dimensions (W x H x L) (mm): 550x850x650 mm Weight: 81 kg drawn arc stud welding gun GD 22 WMS is designed for welding shear connectors with large diameters (19 and 22 mm). Welding range Ø 3-22 mm Welding material steel, stainless steel Stud length 10-525 mm Welding method (acc. to DIN EN ISO 14555) stud welding with ceramic ferrule, stud welding with shielding gas Lift 0-6 mm, adjustable (raster: 0,3 mm) Welding cable: 2 m, 95 mm², outside Control cable plug: 12-pin Dimensions (WxHxL): 68x180x295 mm Weight (without cable): 2,45 kg The new drawn arc stud welding gun GD 22 is designed for welding shear connectors with large diameters (19 and 22 mm). The ample-dimensioned adjustable lift (adjustment range: 0-6 mm) ensures in combination with the adjustable hydraulic piston damper optimum welding results in this diameter field. Of course, the new guns are suitable for welding through metal deck. Ijdpsy Tqwysfx Aa Ieth The gun also features a piston with linear ball track, an automatic length compensation system for different stud lengths and surface conditions as well as a robust, impact resistant housing for the hard work on the construction site. The high-grade outside welding cable (cable cross section 95 mm²) accommodates the high welding currents that are necessary for large stud diameters. Optionally, the new guns can be equipped with integrated travel measuring system. Using this the lift adjustment couldn`t be easier. Moreover, it enables a quality monitoring by measuring and recording of stud protrusion before the weld as well as stud travel (lift, immersion depth, immersion speed and short-circuit time) during the weld.
