Designed to meet demanding production cycles, the IS-200 MF automates the welding of nuts, pins, and fittings on metal chassis. The operator simply selects the appropriate device, chooses the program on the IHM Plus, and starts the cycle with a two-hand operation; the closed-loop control adjusts current, time, and force of each pulse, ensuring a consistent and traceable bond.
Main Project Equipment
- Inverter IMF-25 (1 kHz) – Raises the frequency from the 60 Hz grid to 1000 Hz and ensures stable pulses.
- Welding transformer MF4-16,0-7,2-TM-M8-1c – Linear current between 2.5 and 25 kA.
- IHM Plus + IHM Automation (Siemens KTP700) – 250 programs, Operator/Supervisor modes, touch screen.
- Set of vertical welding heads – Water-cooled electrode holders with position transducer and linear guide.
- Modular devices – Specific supports for brackets, fittings, and reinforcements, with pin guides and brass insulations.
- Thermo Chiller cooling system – Water inlet/outlet via Ø 10 mm hoses for thermal control.
- Electrical panel (440 V, 200 A) and pneumatic (5–7 bar) – Safety relay, FESTO valves, and dedicated manifold.
- Enclosure with Schmersal light curtain – Casters, magnetic switches, and three-color light tower.
