Products

Compact DC Resistance Welding Power Supplies - m1 Series

The m1 Series is a compact, lightweight resistance welding power supply range that blends leading-edge power technology with affordable pricing.
The range offers high-speed closed-loop adaptive feedback control with embedded monitoring, making it the ideal tool for a wide range of joining applications where quality is crucial.
The m1-10 unit offers precision linear technology for low-current applications.
The m1-40 uses a hybrid fast-response twin loop HFDC system for higher current applications.


Specifications

  • High-speed closed-loop output control for consistent welding process definition and control.
  • Constant current, voltage and power modes with programmable double pulse combinations.
  • Simple to use, intuitive menu.
  • Compact, high performance and low cost.
  • Single-phase 95 VAC to 265 VAC operation.

 

Linear DC Power Supplies - m2 Series

The linear DC resistance power supply m2 Series is designed for medium-duty resistance welding applications requiring a high degree of process control and real-time data capture.

The m2 Series succeeds in combining the control and precision of closed-loop DC welding with the economy, ease of use and compact packaging of traditional open loop welding technologies such as capacitor discharge (CD) and AC welding. With better performance than alternative low-cost inverter systems, the m2 offers a solution for any application where precision control is required. Typical m2 product applications include miniature contact welding, battery tab welding, battery pack assembly, conductive material welding and lamp manufacturing.


Specifications

  • High-speed, low-ripple closed-loop output control for consistent welding process definition and control.
  • Constant current, voltage and power modes with programmable multi-pulse combinations.
  • Built-in process and limits monitor.
  • Compact, high performance, high duty at affordable pricing.
  • High-speed automation and communication ports.

 

High Duty DC Spot Welding Power Supplies - m31 SMART Series

The m31 SMART Series of HF DC resistance welding power supplies is designed for high-duty, demanding resistance welding applications requiring a high degree of process control and real-time data capture. Models are available from 6000 to 18000 amps @ 5% duty with <1% ripple. The units employ a unique twin loop control circuit enabling HFDC technology to provide performance similar to Linear DC. The unique system ensures a minimal output ripple across the entire operating range, thereby permitting highly accurate process measurements to be taken in real time.  

The m31 SMART Series offers a precise and responsive control of welding output for applications requiring larger currents, such as miniature contact welding, wire and lead termination, welding of automotive electronics and battery pack assembly.


Specifications

  • 6000 / 12000 / 18000 Amp Versions.
  • Current, Voltage and Power Control.
  • Single-phase and 3-phase input available.
  • Programmed pulse times as low as 0.1 ms for short pulse applications.
  • Real-time feedback and process correction.

 

Single Phase Linear DC Power Supplies - DC1013-613-T Series

The DC1013-T and DC613-T are high-performance 1000 amp precision Linear DC spot welding power supplies that combine touch-panel integrated database process control and monitoring with a high-accuracy, zero-ripple linear transistor output stage that delivers ultra-fast 10 µs dynamic process response rates, with absolute closed-loop 1 amp incremental accuracy and repeatability.

These Single-Phase Linear DC Power Supplies are typically used in aerospace or the medical sector for precision joining of small and fine components. 


Specifications

  • Negligible ripple and extremely high accuracy : 1%
  • Fine incremental current steps – 5 A to 1000 A in 1 A steps.
  • Constant Current, Voltage and Power modes with programmable multi-pulse combinations.
  • Built-in process and limits monitor.
  • High-speed automation and communication ports.

 

High Duty DC Spot Welding Power Supplies - DC2013-T

The DC2013-T HF DC resistance spot welding power supply is designed for high duty, demanding resistance welding applications requiring a high degree of process control and real-time data capture. The DC2013-T is a precision closed-loop servo-controlled resistance welding power supply, taking spot weld verification and quality control to new levels within the industry. Fully closing the process loop on weld quality generation and verification within a single unit increases flexibility and reduces process and plant costs.

Elevated output voltages and a narrow footprint make it an ideal choice for automation applications.


Specifications

  • Maximum Output Current: 3000 amps @ 8 V DC
  • Maximum Output Power: 24 kW
  • Full Output Duty Cycle : 6% @ 2000 A (3% @ 3000 A)
  • Current, Voltage and Power Control - 1 amp incremental steps from 5 amps to 3000 amps - 1% accuracy
  • Built-in SPC data collection and analysis features
