POWER FEED 25M & 25M ALUMINUM
GMAW-STT WELDING
®
Surface Tension Transfer, or STT
process offered exclusively by the Lincoln Electric Company.
STT ® is a low heat, low spatter process created with Waveform
Control Technology ® . STT ®
root welding, welding on thin materials or welding on parts with
poor fit-up. Low spatter, even when using 100% CO
gas, results in cost savings in gas and part clean-up.
Several sets of STT ® weld modes are available.
• Non synergic modes provide individual control of peak current,
background current and tail-out. Some modes also provide for
adjustment of hot start.
• Synergic STT ® modes keep the arc characteristics the same
when the wire feed speed is changed.
®
Note that STT is available only with specially equipped Power
Wave power sources, like the Power Wave 455M/STT or the
Power Wave S350 + STT Module.
For best results:
• Attach the work sense lead as close as possible to the
welding arc.
• Use only solid steel, stainless steel or silicon bronze
electrodes.
