The SAW Tractor is a heavy-production automatic system. It excels at long seam welding on thick plates — but is not designed for positional or light-gauge work.
High-frequency switching delivers stable arc at 85%+ efficiency — significantly lower power bills versus conventional transformer-based SAW machines.
Constant Current for SMAW/SAW and Constant Voltage for MIG/MAG/Hard-Facing — one machine covers your entire production floor.
Under/over voltage, phase loss, internal over-temperature, and IGBT over-current / short-circuit protection — machine safeguards itself automatically.
Prevents wire electrode from sticking to the job at weld end — reduces downtime, protects the torch, and maintains consistent bead finish.
Adjustable inductance lets the welder dial between smooth and rough arc characteristics — critical for different wire types and joint configurations.
Programmable crater voltage/current (triggerable from torch) plus ArcForce and HotStart for reliable out-of-position starts on dirty metal.
Long seam and girth welds on thick-walled vessels and heat exchangers
