DINSE MQZ 305.neo Liquid-Cooled MIG/MAG Torch
Description
550 A liquid-cooled MIG/MAG torch with a ball joint
The DINSE MQZ 305.neo is a manual MIG/MAG torch set for heavy-duty welding up to 550 A. It uses DINSE’s dual-circuit liquid cooling, where coolant flows through concentric ducts along the whole torch neck and cools the contact tip and gas nozzle at the same time, and a ball joint on the torch side with kink protection that lets the hose move freely in all directions.
DINSE rates the torch at 550 A with CO2 and 500 A with mixed gas at 60% duty cycle (DIN EN 60 974-7), for wire from 1.2 to 2.0 mm. The catalogue lists non-alloyed and alloyed steels as applications, as well as aluminium, magnesium, copper and nickel alloys. A separate shield gas hose comes as standard on all MQ(Z).neo torch sets to improve gas coverage and avoid gas losses.

| MQZ 330.neo | Liquid | 400 A / 320 A | 1.0 – 1.2 mm |
| MQ 330.neo | Gas | 300 A / 270 A | 1.0 – 1.2 mm |
| MQZ 230.neo | Liquid | 270 A / 250 A | 0.8 – 1.0 mm |
| MQ 230.neo | Gas | 250 A / 200 A | 0.8 – 1.0 mm |
Selection and compatibility
Choose the length (3, 4 or 5 m) and the machine connection first. The SAZ versions have the machine-side connection fitted as listed, the N versions need a Power Pin or Power Pin set that matches the wire feeder, and the catalogue refers to a Euro-connector variant. Wear parts are compatible within the DINSE 305 series, with gas nozzles of 17 and 21 mm, screw-adapter nozzles of 15, 18 and 21 mm and a narrow gap nozzle of 15 x 125 mm available.
For extreme applications the catalogue notes a cooling jacket with screw adapter DIX SAD 5700 for direct liquid cooling. Use a recessed contact tip where optimum gas coverage is required, and match the liner to the wire diameter and torch length. Check the power source’s cooling unit capacity against a 550 A torch before ordering.
Documents and quotation
The attached DINSE MQ(Z).neo flyer lists the series data; article numbers and wear parts come from the DINSE manual welding catalogue (2022). Other DINSE torches appear under TIG Torches and MIG Guns, including the MZ 304.PLUS.
For a quotation, give the torch set article number or length, the machine connection, wire diameter and material, and the liner and wear parts required.

About brand
DINSE, headquartered in Norderstedt near Hamburg, Germany, develops and manufactures welding torches and systems for manual, robotic and automated welding. The company is widely known for the DINSE coupling, the cable connector found on many welding machines, and for its DIX range of torches, wear parts and wire feeding systems. DINSE works to a quality management system certified to DIN EN ISO 9001:2015.
Seven Star LLC is an independent supplier in Muscat. We list the DIX MZ 304.PLUS liquid-cooled MIG/MAG torch and source DINSE torches, connectors and wear parts on request.
DINSE product groups
The manual welding range covers gas-cooled and liquid-cooled MIG/MAG torches, including the PlusLine handles for the 304 and 330 series, push-pull torches and fume extraction torches. For automated welding the manufacturer offers robot torches, TIG automation and laser wire feeding. Further groups are plugs and sockets, wire feeding systems such as drum feeders, and spare and wear parts.
Ordering DINSE torches and wear parts: what we need
State the full torch designation, the cable assembly length, the cooling type and the machine-side connection on your wire feeder, either DINSE or Euro connector. Add the wire diameter and material, since liner and contact tip depend on them. For wear parts, send the DIX part name or part number, or a photo of the old part with the torch type.
