// The Machine
One Machine. Every Metal. Professional Results.
The RETOP WSE 250 is a full industrial AC/DC TIG inverter built for workshops that demand the best. Whether you're repairing a cracked aluminium engine block, fabricating a stainless steel exhaust, or welding up a brass fitting, the WSE 250 delivers clean, controlled, professional-quality welds every time.
Available through Weld.lk — Sri Lanka's leading welding equipment supplier — the WSE 250 brings together MOSFET inverter technology, dual AC/DC output, and a 2-year warranty in one workshop-ready package.
// Engineering Advantage
MOSFET Inverter Technology — Built for Precision
At the heart of the WSE 250 is a MOSFET-based inverter circuit — the technology trusted by professional fabricators worldwide. MOSFET inverters switch at frequencies of 20,000 to 100,000 Hz, delivering an arc that is dramatically more stable, responsive, and controllable than older transformer-based machines.
In practice: smoother arc starts, tighter heat control, reduced spatter, and a weld pool you can actually steer. On delicate sections like thin aluminium panels or gearbox casings, that level of control is the difference between a perfect repair and a ruined component.
The inverter design also makes the WSE 250 significantly lighter and more energy-efficient — easier to move around the workshop, and easier on the electricity bill.
// Why AC/DC Matters
The Complete Solution for Aluminium Welding
Aluminium carries a natural oxide layer that melts at nearly three times the temperature of the metal beneath it. To weld aluminium properly, you need alternating current (AC) — the electrode-positive half-cycle provides cathodic cleaning that blasts away the oxide, while the electrode-negative half-cycle delivers penetration and fusion. The result is bright, clean, porosity-free welds on engine blocks, gearboxes, and alloy structures.
For steel and stainless, DC output gives a tight, directional arc with deep penetration and minimal distortion. The WSE 250 switches between both modes — making it the only TIG machine your workshop needs.
// What You Can Weld
Built for the Jobs That Matter
Engine Blocks & Cylinder Heads
Crack repairs, casting porosity fill, and structural welding on aluminium engine blocks and cylinder heads. AC TIG delivers the controlled heat and clean fusion these precision components demand.
Gearbox & Transmission Cases
Aluminium gearbox housings and bell housings are ideal for AC TIG repair. The WSE 250 cleans the oxide layer and achieves full-penetration welds without cracking surrounding cast material.
Alloy Wheels & Chassis Fabrication
Crack repair on alloy wheels, roll cage and chassis fabrication, suspension brackets — AC TIG gives you the clean, aesthetic welds that aluminium fabrication demands.
Marine & Structural Aluminium
Boat hulls, marine hardware, and structural aluminium profiles. The WSE 250's stable high-frequency arc start and smooth AC balance control ensure consistent, quality welds.
Stainless & Mild Steel
Switch to DC for stainless steel food-grade fabrication, industrial pipework, structural mild steel, and all general workshop TIG welding. One machine for your full scope.
Brass & Non-Ferrous Metals
Brass fittings, bronze components, and copper alloys — the WSE 250 gives your workshop versatility for maintenance, decorative, and custom fabrication work.
