High Force Servo-Motor Driven Weld Head - Model 73

Product catalog summary

Overview: The document provides detailed information about the 70 Series Servo Motor Driven Weld Heads by Amada Miyachi America, designed for resistance welding applications. These weld heads are suitable for automation or benchtop welding, offering precise control and programmability.

Key Features:

Programmable speed and positions with up to 32 motion schedules.
Controlled servo motor actuation to prevent overforce and ensure low-end force control (0.25 lbs).
Soft Touch part clamping for minimal impact force and part alignment verification.
Fast follow-up for consistent welds and reduced weld splash.
Overforce protection for repeatable force and reduced part deformation.
Constant applied force independent of part height for weld repeatability.

Technical Specifications:

Programmable electrode positions accurate to .004 inches.
Electrode stroke of 1.5 inches max, adjustable in .004-inch steps.
Force range of 0.25 – 8 lbs per electrode, dependent on spring used.
Electrode speed adjustable in multiple stages, with speeds ranging from 20-300 mm/s and 7.5-30 mm/s.
Power supply requirement of 100 - 220 VAC 50/60 Hz and welding current of 3000 amps @ 2% DC.

High Force Servo-Motor Driven Weld Head - Model 73-1

Servo Motor Driven Weld Heads • Programmable speed and positions • Controlled servo motor actuation eliminates overforce • Extremely low-end force control (0.25 lbs) • “Soft Touch” part clamping • Displacement and force options communication • Unitip and blade thermode option TYPICAL APPLICATIONS Designed for use in automation or benchtop welding, Amada Miyachi America’s 70 Series servo motor welding heads offer fast, repeatable electrode motion control for a wide range of resistance welding applications. Two different models are available, each equipped with an easy-to-program, state-of-theart servo motor controller that allows precise programming of electrode position and speed for up to 32 different weld schedules. Solar cell KEY FEATURES • Write and save up to 32 motion schedules • “Soft-touch” part clamping minimizes impact force and allows verification of part alignment prior to welding • Fast follow-up means less weld splash and more consistent welds • Individual speed control for “stroke to search” and “search to weld” increases flexibility and throughput; good for automation Pacemaker interconnects • Overforce protection ensures concise repeatable force, less weld splash, and reduced part deformation • Constant applied force - independent of part height - ensures weld repeatability • Easy programming and fast, efficient schedule adjustment 0.002 in diameter magnet wire to gold pad RESISTANCE WELDING
