High Frequency Welding Control HIGH RELIABILITY MICROJOINING The HF Series high frequency weld controls address the challenges of micro welding for a wide range of applications. Precise control of weld energy with high speed closed loop feedback and weld quality tools ensure high yields for the most demanding welding applications. HF series weld controls are also geared for automation featuring exceptional repetition rates, standard I/O connections and remote programming capability. KEY FEATURES CONTROL FEATURES: • Constant current, voltage, and power modes TYPICAL APPLICATIONS • Monitors energy and resistance • 2400 A maximum • 25 kHz feedback WELD QUALITY PROCESS TOOLS: • Active Part Conditioning (APC) Anti-lock brake system solenoid Critical parts fabrication Switch assembly Implantable device interconnects • Pre-Weld Check • Weld to Limits HF27 ADVANCED FEATURES: • Displacement and force monitoring • Force control • Envelope function • Combo mode • Energy and time limits RESISTANCE WELDING

CURRENT, VOLTAGE AND POWER FEEDBACK MODES: INTUITIVE, EASY-TO-USE • Intuitive graphical user interface. • Dual pulse waveforms programmed in current, voltage, or power control modes. • Programming times to 100 usee increments provides ultimate control. • Accurate, built-in monitor displays the graphical "trace" of weld current, voltage, power and resistance, along with numerical peak and average values. • Easy-to-set limits establish process window • User programmable relays can be used in conjunction with visual and audible signals for operators and automation interface. • Compensates for parts...
