Explore our export-ready automated weaving systems, fiber laser cutters, high-capacity wire feeders, and specialized welding positioners built for continuous industrial duty.
The manufacturing ecosystem in the Czech Republic—celebrated for its centuries-old engineering lineage in heavy machinery, automotive assembly, pressure vessel fabrication, and rail transit manufacturing—is navigating a vital transformation. Heavy metal fabricators in key industrial hubs such as Ostrava, Plzeň, Brno, Liberec, and Prague face dual pressures: maintaining rigorous compliance with European structural standards (EN 1090-2, ISO 3834-2, EN 13445) while mitigating an unprecedented structural deficit of certified European Welding Engineers (EWE) and manual welders.
To overcome these challenges, progressive Czech fabricators are systematically moving away from strictly manual arc weaving toward programmable linear welding oscillators and motorized torch weaving carriages. Advanced Power Sources Limited (APS Welding) stands at the forefront of this industrial transition, manufacturing micro-processor-controlled welding oscillators designed to integrate seamlessly into MIG/MAG (GMAW), TIG (GTAW), Submerged Arc Welding (SAW), and hardfacing automation cells throughout Central and Eastern Europe.
By automating the transverse weaving motion of the welding torch with controlled left/right dwell times, precise amplitude regulation, and synchronized travel speed, continuous weld defect rates (such as undercut, lack of side-wall fusion, and irregular bead ripples) are reduced by up to 88% compared to semi-automatic manual operations. This level of repeatability ensures that Czech manufacturers satisfy stringent non-destructive testing (NDT)—including Ultrasonic Testing (UT) and Radiographic Testing (RT)—on thick-section welds.
Designed for extreme duty cycles in harsh fabrication environments, our linear and angular welding oscillators utilize high-torque micro-stepping motors, zero-backlash ball screws, and heavy EMC-shielded digital control units.
Offers versatile weaving algorithms including Linear Trapezoidal, Triangular, Square Wave, and Pendulum oscillation patterns. Operators can independently adjust oscillation width (0–50 mm) and step resolution down to 0.1 mm increments.
Prevents side-wall undercut on heavy structural plates by providing independent left, right, and center dwell time control (0.0 to 10.0 seconds). Ensures perfect heat saturation and tie-in on multi-pass butt and fillet joints.
Features standardized relay contact control interface compatible with all major inverter power sources (MIG/MAG, TIG, Submerged Arc, and Fiber Laser welding heads). Easily mounts onto welding carriages, manipulators, and gantry systems.

As an established manufacturer and global exporter of industrial power sources, plasma cutters, and welding positioners, Advanced Power Sources Limited (APS Welding) enforces rigid Quality Control (QC) protocols certified under ISO 9001:2015. All equipment exported to the European Union and Czech Republic strictly complies with relevant European Directives:
Unlike trading intermediaries, APS designs and manufactures micro-controller control boards, inverter power modules, and mechanical drive mechanisms in-house, giving our engineering team direct control over software update customization and hardware longevity.
We maintain streamlined export channels to Central European destinations, facilitating smooth customs clearance into Czech Republic (Prague Airport, Hamburg/Stettin sea corridors, or direct road logistics) with complete EUR.1 / COO documentation.
Every oscillator system includes detailed English user manuals, wiring schematics, digital parameter setup guides, and direct engineer-to-engineer video support for rapid commissioning.
Addressing key commercial, technical, and regulatory inquiries for seamless importing into the Czech Republic.
Standard model welding oscillators and motorized carriages are typically dispatched within 7 to 10 business days following order confirmation. Air freight delivery to Prague (PRG) airport typically takes 4 to 6 transit days, while door-to-door ocean freight (via Hamburg, Bremerhaven, or Koper) followed by rail/truck transport to Czech hubs takes approximately 22 to 28 days. Express courier service for urgent spare parts is available with a 72-hour turnaround.
Yes. All APS automated welding oscillators, linear carriages, and power sources delivered to the Czech Republic carry the CE mark and conform strictly to EU Directives, including 2014/35/EU (LVD) and 2014/30/EU (EMC). Comprehensive Certificates of Conformity (DoC) and test reports are supplied with each shipment to support your internal ISO 3834-2 and EN 1090-2 quality audit trails.
Absolutely. APS oscillators feature universal dry-contact trigger interfacing and adaptable mounting brackets. Whether your workshop operates Fronius, ESAB, Miller, Lincoln Electric, or APS welding sources (MIG/MAG, TIG, or SAW), our control box seamlessly syncs arc start, arc stop, and travel carriage motion automatically.
The control units operate on standard European single-phase AC 230V (±10%), 50Hz electrical supply. Internally, a stabilized transformer converts this to low-voltage DC (24V/36V) to power the high-torque micro-step motor safely, protecting operators and ensuring stable motion even during power grid fluctuations.
In thick-plate multi-pass V-butt or J-prep joints, manual welding often suffers from side-wall cold laps or incomplete root penetration due to irregular torch manipulation. An automated linear oscillator ensures exact dwell timing at both side walls, allowing the molten weld pool to flush perfectly into the parent material before stepping forward. This results in ultra-clean radiographic and ultrasonic profiles free from slag inclusions.
APS provides a standard 12-month comprehensive warranty on all mechanical drive units, stepper motors, and digital control modules. We maintain a complete inventory of plug-and-play replacement boards and drive components ready for immediate dispatch via DHL/TNT. Our senior technical team also offers direct remote video assistance for parameter tuning and integration guidance.
