Weld Heads Amada Miyachi's Thin-Line Heads for spot welding applications comprise three families of fullfeatured products for resistance spot welding: 80 Series (20 lbs (89N) - 40 lbs (178N)), and 180 Series (100 lb (445 N)). All are precision, low inertia, force-fired designs, with narrow vertical profiles. Inline and parallel gap spot welding configurations available. Ideal for both production line and benchtop applications, Thin-line weld heads can operate at speeds greater than 3600 welds per hour. TYPICAL APPLICATIONS KEY FEATURES • Low inertia, fast follow-up designs improve weld consistency, reduce metal expulsion, and improve weld appearance • Adjustable force firing ensures weld force is independent of electrode stroke length resulting in higher quality welds Magnet wire to terminal • Patented EZ-AIR technology ensures force consistency and simplifies set-up • Rugged industrial design improves productivity, minimizes repair costs and ensures long life • Pneumatic or manual actuation Coin cell battery tab Honeycomb tacking RESISTANCE WELDING

RESISTANCE WELDING PRECISION PERFORMANCE THROUGH INTELLIGENT DESIGN The Thin-Line Ranges Amada Miyachi's Thin-Line Weld Heads consist of two families of full-featured products for precision metals joining: 80 Series – 0.25 to 20 lbs. (1.1 to 89 N) 4 to 40 lbs. (18 to 178 N) 180 Series – 5 to 100 lbs. (22 to 445 N) Durable High Quality Design Rugged construction, linear ball bearing bushings and an over-sized, anti-rotation bearing system provide perfect linear travel of the upper electrode arm. This system minimizes the potential for electrode wiping action during the weld, even at maximum...

RESISTANCE WELDING HIGH QUALITY, FULL FEATURED All Amada Miyachi weld heads are subjected to environmental life testing designed to guarantee specifications and performance. Air actuated weld heads are supplied with an EZ-Air force control module. The air actuation system includes a linear spring which ensures proper operation at low forces. EZ-Air provides high repeatability and eliminates overforce. The air systems can be moved to other locations when the heads are incorporated in work stations or automated systems. The heads can be supplied with an optional Hall Effect Limit Switch Kit,...

RESISTANCE WELDING EZ-AIR TECHNOLOGY The EZ-AIR weld force control system simplifies the set-up process to a single adjustment and helps prevent weld over-force by closing off the input air when the actual weld force reaches the programmed weld force level, delivering accurate force control which is repeatable across multiple weld heads without complex setup or operator training. • Firing force is important because it controls contact resistances and, therefore, heat generation at the electrode-to-part and partto-part interface. • Superior force control = process stability and higher...
