GMAW-STT™ WELDING
Surface Tension Transfer, or STT™ welding, is a
break-through process offered exclusively by the
Lincoln Electric Company. STT™ is a low heat, low
spatter process created with Waveform Control
Technology™. STT™ is the process of choice for
open root welding, welding on thin materials or weld-
ing on parts with poor fit-up. Low spatter, even when
using 100% CO
2
shielding 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.
