70 Series - Servo Motor Driven Weld Head
Designed for use in automation or benchtop welding, AMADA WELD TECH's 70 Series Weld heads offer stable, repeatable electrode force for a wide range of resistance welding applications. Two different models are available, each equipped with an easy-to-program, state-of-the-art servo motor controller which allows the electrode positions to be precisely programmed and a speed of up to 32 different weld schedules.
Key features 70 Series - Servo Motor Driven Weld Head
- 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
- 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
Servo Motor Driven Weld Heads
Programmable electrode positions – accurate to .004 in
- “Home” position allows for easy access during maintenance
- Electrode in the “Upstop” position in the “Ready” state
- The first level of the footswitch moves the electrode down to the “Search” position at a programmable “Soft-touch” speed
- The second level of the footswitch applies the pre-set welding force, with no overforce
- Programmable “Downstop” inhibits welding if parts are not present
