What is MAWA-300B/MAWA-050A PULSETIG® Welding Power Supply?

This DC type TIG welder generates arcs between an object to be welded and the tungsten electrode and carries out welding using the generated heat.
Effective for welding of precision devices and minute parts.
Individual lineup of high voltage start special purpose machines and touch start special purpose machines.
Selecting the start method appropriate for the workpiece improves the welding reliability.

Features

  • Feature of each start
    • ● Touch start
    • Touch electrode and work piece before start, pull up electrode, make magnetic field between electrode and work piece, generate arc
      • Suppress influence of noise
        Suppress causing malfunction of electrical device and breaking electrical parts with weak electrical strength near the welding point.
      • Secure weld on chosen point
        Arc will cause from electrode touching point to electrode. This will secure place to weld.
      • Reduction of the running cost
        Electrode life is prolonged , compared with the high voltage start, running cost can be reduced.
    • ● High voltage start
    • Cause arc by adding DC high voltage between electrode and work piece Position of electrode will be fixed on same place for all the time
      • Non-contact
        Effective in welding small parts as the arc is shot without contact.
      • Non-pressurized
        Since electrode does not touch work piece, able to reduce distortion of work piece.
      • Short takt time
        This method is more effective than the touch start method in reducing the takt time because it is not necessary to vertically move the torch.
  • Controller can be separate from unit by using option cable
    Controller can be separate from unit by using option cable
  • Pulse modulation feature
    Inner blow halls generated at welding are reduced due to this feature which inputs heat intermittently.
    Size and shape of arc ball is controllable.
  • Envelope feature
    The upper and lower limit of criterial current waveform are set to judge welding quality.
    Touch start feature

* ON/OFF of pulse modulation can be set to each Up Slope /WELD /Down slope of WELD1 and WELD2.

*1:Only the touch start functions.

TOUCH START HEAD MH-TL01A

TOUCH START HEAD MH-TL01A

  • Weld head that can be easily connected to the MAWA-050A (a model dedicated for touch start)!
  • The torch is motor driven exclusively for the MAWA-050A (a model dedicated for touch start).
  • The dedicated controller easily sets the electrode position and speed.
  • Torch floating lock feature
    The MH-TL01A keeps a certain torch hoist amount even if the workpiece height varies.
    This realizes a stable penetration amount.
