Welding process expanded to work with thin-gauge materials
Lincoln Electric® has expanded its patented STT® (Surface Tension Transfer) welding process to work with thin-gauge materials. The new AC STT waveform handles thin sheet metal from 24 ga. and up while accommodating for poor fit-up and gap conditions.
The modified, short-circuit GMAW process originally was engineered for low-spatter root-pass pipe welding. The new expansion combines this low-spatter technology with the control heat-input characteristics of AC GMAW, helping to reduce burn-through while maintaining high deposition rates.
The technology is available as a free waveform upgrade for the Power Wave® S500, R500, and R450 with the Advanced Module.
