Arc welding machine reduces spatter, saves costs

A gas metal arc welding machine that uses high frequency inverter technology with advanced waveform control reduces spatter and smoke, providing significant saving on weld cleaning.

By using of high frequency inverter technology with advanced waveform control The Lincoln Electric Company has developed its 'Surface Tension Transfer' (STT) gas metal arc welding (GMAW) process.

Use of this patented inverter-based power source significantly reduces spatter and smoke.

The STT power source has the basic power platform used by other inverter power sources, but the electronics more closely monitor and control the arc welding current.

The STT process can be used with 100% carbon dioxide shielding gas in combination with electrodes ranging from 0.030in to 0.045in (say 0.8-1.1mm) diameter.

These two STT process features can produce significant cost savings.

The STT process can use 100% carbon dioxide, blends or argon and carbon dioxide or helium mixtures as shielding gas for stainless steel and will reduce spatter and smoke.

Reduction in spatter can result in significant cost savings through minimizing final weld surface cleaning or reducing the maintenance of welding fixtures.

It also allows extended welding periods before having to clear the gun nozzle of accumulated spatter.

Reduced smoke and spatter also gives this process a high operator appeal, leading to improved performance.
