- 2. MH-1201A MH-1301A Force Range: 70 -265 lbs. Force Range: 97-393 lbs. 10kA Secondary 10kA Secondary Key Features Key Features • Integrated in-line spring for fast follow-up Integrated transformer inside head • Precision linear bearings for long life • Low friction cylinder for fast follow-up • Precision anti-rotation bearing ensures proper • 3-inch stroke for easy part loading alignment of upper electrode assembly • Lower T-slot platen for custom tooling • Optional displacement sensor mount • Throat depth 8 inches • Optional internal load cell • Throat depth 2.9 inches The MH-1301A head has a solid welded frame with provision for an internal mounted transformer. The head The MH-1201A head is an in-line weld head with features a cup style cylinder for fast follow-up, and has spring follow-up, mounted to a rigid extrusion. an optional lower electrode holder. Match to the IS-120B inverter for light-to-medium welding applications. MG3 Digital Process Monitor Miyachi Inverters Matched to Key Features Inverter Key Features • Monitor current, voltage, displacement, • 1 kHz feedback frequency and force • Secondary and primary RMS or peak constant • Set limits and process envelope for all current, voltage, power control modes parameters • Built-in monitor and limit setting for current, • Time stamped data logging • Full on-screen SPC capability voltage, power and time • Can be used on any welder • Matched plug-and-play transformers • Optional programmable force control weld-to- displacement interrupt STA-100 AC Key Features • Percent heat and primary RMS control modes • Monitor RMS current and conduction angle • Optional voltage monitoring and electronic pressure regulatio • Differential pressure monitoring The MG3 provides an invaluable window into the welding process. Being able to see overlayed current, voltage and displacement traces provides a key understanding of the weld. Once a weld is optimized, the MG3 can be used to envelope a waveform, program warning and out-of-process limits, as well as provide full SPC data logging and analysis.
- 3. MH-1501A / MH-1601A Force Range: 250-1570 lbs. 24/40kA Secondary Key Features • Benchtop or pedestal options • Low inertia ram with integrated accelerator for fast follow-up • Ram mounted to slide with zero clearance ball bear- ings to ensure precise movement • Many cylinder options for different force ranges • Throat depth 8 inches The MH-1501A and larger MH-1601A are high performance weld heads with the flexibility to optimize the force range to the application. Five different cylinder options mean that the head is always working in the best force and follow-up combination. MH Range MM-380A Handheld Weld Checker Key Features • Measure current, voltage and force • Weld-through sensor measures current and force between the weld electrodes • Easy screen navigation with thumb wheel and intuitive on-screen analysis • RS232 output • Auto shut-off promotes long battery life on Force and current trace provides optimization tool for timing.
