Engineered specifically for heavy engineering, vessel fabrication, wind towers, structural steel, and long-seam pipe production. APS Endeavour Series SAW power sources deliver deep penetration, low energy operational costs, and 100% duty cycle performance under continuous industrial workloads.
Submerged Arc Welding (SAW) is an automated wire-fed process where the arc burns beneath a blanket of granular protective flux. This enclosed arc eliminates ultra-violet flash, reduces spatter to near-zero, and achieves extremely high metal deposition rates unattainable by manual arc or MIG processes.
At Advanced Power Sources Limited (APS Welding), our Endeavour Series SAW power sources integrate advanced IGBT module inverter technology. Compared to legacy transformer-rectifiers, our systems reduce grid power consumption by up to 35%, offer digital constant-current (CC) and constant-voltage (CV) arc control, and integrate seamlessly with column-and-boom manipulators or self-propelled welding tractors.
Complete single-source packages engineered and built under strict ISO quality standards in Gujarat, India for overseas B2B fabricators.
1000 Amperage heavy-duty multi-process inverter source ideal for medium-to-thick plate structural welding and vessel seams.
Flagship 1250 Amperage power source designed for continuous heavy section welding, thick pressure vessel shells, and heavy structural beams.
Self-propelled digital travel carriage for precise longitudinal butt and fillet seam tracking with smooth wire feeding.
Heavy-duty vacuum recovery system that reclaims un-fused flux automatically during welding to cut material cost and keep worksites clean.
