Trafimet ERGOPLUS 500 Water-Cooled MIG Torch

A 500 A water-cooled MIG torch for continuous heavy welding

The Trafimet ERGOPLUS 500 is a water-cooled MIG/MAG torch rated at 500 A with CO2 and 450 A with mixed gas at 100% duty cycle. It accepts wire from 1.0 to 2.4 mm, which covers heavy solid and flux-cored wires used in structural steel, earthmoving equipment and thick-plate fabrication. Coolant flows through the neck to the front end, so the torch can run at high current for long periods.

It has the ERGOPLUS rubber-textured handle and the MT0566 pistol grip, and connects through a EURO central connector with separate coolant lines.

Technical specifications

Front-end parts and cable assembly

Nozzles in the sheet include MC0268 (2.5 mm wall, 16 mm bore), MC0340 heavy duty with 3 mm wall, and quick-release types MC0568 and MC0576. Contact tips are M8 CuCrZr, from MD0005-80 for 1.0 mm to MD0005-86 for 1.6 mm wire, on brass or copper tip holders. Uncoated steel liners GM0530 to GM0532 cover 1.2 to 1.6 mm wire. The cable assembly MN2014, control leads BX1421 and gas hose are listed for each length.

Cooler requirements

A recirculating cooler must deliver at least 1.6 l/min at 2 to 4 bar. Running a water-cooled torch without flow, or below the minimum, damages the neck and front end within seconds at high current. Check that the cooler outlets match the hose fittings and that the coolant is the type the cooler maker specifies. For work below about 300 A without a cooler, the gas-cooled ERGOPLUS 36 is simpler.

Heavy-duty quick-release nozzles let the welder change front ends quickly without tools, which reduces stoppages on long production runs. Choose a nozzle bore and stick-out to suit the process: a smaller bore improves access in deep grooves, while a larger bore gives wider gas coverage at high deposition rates. For flux-cored wire of 1.6 mm and above, confirm liner and tip sizes against the full Trafimet consumable list before ordering.

Check the coolant level and flow before each shift. Air in the circuit or a blocked hose reduces flow without warning, so a cooler with a flow switch is recommended. Drain and refill the cooler at the interval its maker recommends.

When a long cable package is needed, consider placing the cooler and feeder closer to the work instead, because a shorter torch is lighter and easier to guide at high current.
