The IS-360 MF was created for processes that require high energy and millimeter control. The operator fits the appropriate device, selects the program on the IHM Plus, and starts the two-handed cycle; the machine performs rapid welds, monitored in closed loop by the 1 kHz inverter.
Main Integrated Equipment
- 2 inverters IMF-35 (1 kHz) – Double pulse, linear current, and low thermal losses.
- 2 transformers MF4-16,0-7,2-TM-M8-1c – Current from 7 to 35 kA for cycles of 250 kVA/20%.
- Welding heads vertical (upper/lower) – Cooled electrode holders and fine adjustment.
- IHM Plus + IHM Automation (Siemens KTP700) – 250 programs, Operator/Supervisor modes, detailed alarms.
- Electrical panel (380 V, 200 A), pneumatic (5–7 bar) and hydraulic – With SRB 301MC relay, safety valve, and Thermo chiller.
- Complete enclosure – Structure in profile 40 × 80, Schmersal SLC440 light curtains, signaling tower.
- Modular devices (20+ models) – Cradles dedicated to different parts, with pneumatic extraction and fixing magnets.
- Mobile disposal ramp – Segregates OK/NOK parts into bins, with wheels and articulated closure.
