Cloos Qineo Pulse 600 QWD-Twin with a MASTER panel is an industrial MIG/MAG welder on a large copper transformer with digital control. The source works in a range from 40 A to 600 A, gives 600 A at a 60% duty cycle and 44.0 V and 465 A in continuous 100% work at 37.5 V. What sets the set apart is the QWD-TWIN double feeder with two independent wire paths and two four roll drives.
What this machine is for
Two wire feed paths fed from one 600 A source change the way you work at the station. You load the machine with two different spools, for example structural steel and aluminium or mild steel and flux cored wire, assign separate synergic programs to them and switch over with a short press of the trigger of the right torch. On the panel the LED of the active path lights up, and the controller recalls the parameters last used for that feeder. Changeover disappears: you do not swap rolls, wire or guides when you move to another material. This is not welding with two wires at the same time, the paths work in turn.
On heavy steel structures and multi layer welds you load one path with solid wire for the root run and tacking, and the other with a high output flux cored wire or a larger diameter for fast filling of the groove. A current of 465 A in continuous 100% work lets you run long welds on thick material without waiting for the source to cool down, which is why the machine goes to the machine, rail and shipbuilding industries and to tank production.
The program base covers Fe structural steels under Ar/CO2, Ar/CO2/O2 and Ar/O2 mixtures and under pure CO2, CrNi stainless and acid resistant steels, AlSi and AlMg aluminium alloys under pure argon and under argon and helium ArHe mixtures, MIG braze welding with CuSi and CuAl filler for galvanised sheet and bronzes, and rutile and metal cored wires for carbon and stainless steel. The panel handles wire diameters of 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm and 2.0 mm.
Features and equipment
- Two independent QWD-TWIN feed paths, each with a four roll drive: two spools and two programs at once, switched with the torch trigger, without swapping rolls and guides.
- A large copper transformer with digital arc control: the current circuit takes the thermal loads of the 600 A class and works long cycles on large structures.
- MASTER panel with two large segment displays: you pick the material group, the shielding gas and the wire diameter with buttons and knobs, without going through graphic menus.
- Synergic control: after you point to the material, the gas and the wire diameter you set one power parameter, and the controller picks the voltage and the feed speed.
- Mode without synergy (Syn off): the process engineer switches the curve off and defines the voltage and current characteristic himself for an unusual material or gas.
- MIG/MAG Pulse: the droplet detaches at the peak phase of the current pulse, so there is less spatter and the heat put into the material stays under control.
- SpeedPuls: a focused fast pulsed arc for straight sections of welds, it raises the welding speed without losing pool stability and penetration depth.
- DuoPuls, a double pulse with a separate button: it adds a low frequency modulation, so you control the heat input more closely, bridge assembly gaps more easily, and the bead gets a regular ripple on aluminium and CrNi.
- Fe ArCO2 RapWld program, that is Rapid Weld: a focused spray arc with high pressure and deep penetration, so you reduce the bevel angle on thick plate and lay fewer layers in the groove.
- JOB memory for up to 999 numbers: you save a full set of settings for a repeated part, together with the voltage correction, the arc dynamics and the course of the start and the fade out.
- HOLD function: after a bead the real current and voltage values stay on the display for quality control.
- Torch modes 2T, 4T, Super-4T and spot and interval welding: in Super-4T you control the starting current, the main current and the crater fade from the trigger, which limits crater cracks at critical points of the joint.
- Interconnection cable of about 1 m: the feeder stands on the source, and the losses over a short route are small.
- A set of working cables of 4 m each, that is MIG, earth and supply: the earth cable has a cross section sized for a continuous load of 600 A and a jaw clamp.

What to watch out for
The machine needs an industrial connection of 3 x 400 V at 50/60 Hz, and the input current reaches 48.7 A at the peak and 37.8 A effective, so size the circuit and the fuse for those values, not for a typical workshop circuit. The interconnection cable is only about 1 m, the feeder sits practically on the source, so this is a stationary layout and not a set for walking around a structure. The working cables are 4 m each, so on large parts count the reach or plan a longer set. The open circuit voltage is 84 V, so in tight and damp places keep to the safety rules for industrial sources.
The two feed paths work in turn, so if you are looking for tandem welding with two wires at once, this is not the configuration. The product record gives liquid cooling, and machines from the second hand market come in different configurations, so confirm the torches, the rolls of both paths and the cooling circuit with us before you buy. Protection class IP23 allows the dust and damp of a hall, but not washing with a jet. A source with a copper transformer is heavy, so prepare a forklift for unloading.
How we sell used machines
This unit was checked in our service workshop in Krotoszyn with measurements to PN-EN 60974-4 and a load test. The price includes the first year of the basic service package: an inspection with cleaning of the machine and a validation measurement. Further years can be added. We ship across the European Union, collection in person by appointment.
