Linear DC Power Supplies

Regulated direct current power supplies provide a direct current voltage that is free of harmonic waves. It is essential to use these when welding extremely small parts or certain refractive materials. They offer the same outstanding controllability as inverter power supplies.

Linear DC Spot Welding Control with Built-in Monitor - DC29

The DC29 linear DC resistance welding control is a 200-4000 Amp linear DC control with four feedback modes that is designed to adapt to part and process variables. Weld energy may be programmed in current, voltage, power, or V-A, in increments as short as 0.01 milliseconds. Therefore, this spot welder is ideal for small applications in the electronic component and battery-pack markets.


Specifications

  • Four control modes: current, voltage, power and V-A (voltage-current)
  • Single-phase input
  • Compact size
  • Dual pulse schedules
  • Precisely controlled repeatable waveform
  • Very fast rise time

 

Linear DC Spot Welding Control with Built-in Monitor - DC25

The DC25 Linear DC resistance welding control is ideal for micro joining applications which require exceptional control and the highest quality throughput. Weld energy may be programmed in current, voltage, or power in increments as short as 0.01 milliseconds.

Specifications

  • Superior Low Energy Control for Micro Welding
  • Ultra-Fast Closed Loop Control
  • Real-Time Feedback
  • Single-Phase Power Supply
  • Three Feedback Modes for DC Welders Graphical Display and Intuitive DC Welder Monitoring

 

Low Power Linear DC Micro Spot Welder - UB29

The UB29 linear DC micro spot welder provides unsurpassed levels of control for resistance micro welding and thermo-compression bonding.

UB29 is a 400 Amp linear DC control with four feedback modes designed to adapt to part and process variables. This micro-welding machine should be used for smaller applications where closed-loop feedback control and fast response times are required. Safety critical applications such as those found in the medical and automotive markets will benefit from UB29’s precision low energy control.

MD Series - Linear DC Controls

MDA-10000A is an ultra-fast, high-current linear DC weld control, which can operate in constant current mode, constant voltage mode, or both. It is particularly well suited to series welding applications. The MDA-10000A is ideal for welding optical sensor parts, crystal oscillators, and projection welding of electronic components.

Connect multiple power supplies to achieve high-power welding in a short time frame. Up to twelve MDA-10000A power supplies can be connected in a slave/master configuration to design just the right system for high power/short process welding.


Specifications

  • Monitor constant current, voltage, or both
  • Connect up to 12 units together
  • Switchable polarity
