CLOOS QINEO PULSE 600 MASTER, used MIG/MAG welder

Cloos Qineo Pulse 600 Master is an industrial MIG/MAG welding machine with a Master panel and an external Qineo WD Pulse wire feeder. You set the current from 40 to 600 A, the working voltage from 16 to 44 V, and the duty cycle is 600 A at 60% and 465 A at 100%. The set has an interconnection cable 10 m long and working cables of 4 m each.

What this machine is for

This is a source for heavy production at high current. A load capacity of 600 A in a 60% duty cycle and 465 A in continuous work lets you weld thick steel plate with long beads, without pauses to cool the system. The source is built on a large copper transformer with digital control, so the arc is stable also when the voltage in the hall wavers.

The interconnection cable 10 m long splits the station. The heavy source, weighing over 200 kg, stays in one place and you move the feeder alone to the part: onto a platform, onto a long boom arm or inside a tank. That helps when assembling large steel structures, containers, trailers and machine frames, where rolling the source about takes more time than the welding itself.

The Master panel with two digital displays gives access to synergic programs without going into a deep menu. The database covers structural steels shielded by Ar/CO2, Ar/CO2/O2 and Ar/O2 mixes and by pure CO2, CrNi stainless and acid resistant steels, AlSi and AlMg aluminium alloys in argon and in mixes with helium, CuSi and CuAl braze welding on galvanised sheet, and also rutile, basic and metal cored flux wires as well as stainless ones. You pick the wire diameter from the panel, from 0.8 mm to 2.0 mm.

Pulsed processes order metal transfer. In pulse the droplet detaches in the peak phase of the pulse, without a short circuit, so there is less spatter and you hold the heat put into the material in check. SpeedPuls is a concentrated, fast pulsed arc for raising the welding speed, and the Rapid Weld spray program gives deep penetration, so you reduce the bevel angle on thick plate and lay fewer runs in the groove.

Features and equipment

• Setting range from 40 to 600 A and from 16 to 44 V: one source handles thin sheet at the lower end and thick sections at the upper one, without changing the setup of the station.
• Large copper transformer with digital control: the arc is stable under heavy load, and the build takes the conditions of an industrial hall.
• Interconnection cable 10 m: it splits source and feeder, so the welder works far from the machine, on the structure or inside a tank.
• External Qineo WD Pulse feeder with a 4 roll drive: matched to work at 600 A in a 60% duty cycle, it guides the wire without slip along a long cable package.
• Master panel with two segment displays: current, voltage, program choice and wire diameter are at hand, without a graphic menu.
• Synergic control: you enter material, gas and wire diameter, the controller picks the linked electrical parameters, so fewer trial settings on the part.
• MIG/MAG Pulse: droplet transfer in the peak phase of the pulse, without short circuits, with less spatter.
• SpeedPuls: a concentrated, fast pulsed arc for a higher welding speed with a stable pool and deep penetration.
• Rapid Weld (Fe ArCO2 RapWld): a spray arc with high pressure and deep penetration, it lets you reduce the bevel angle and the number of runs in the groove.
• DuoPuls, that is double pulse with its own button: modulating the pulse with an extra low frequency orders the heat input, bridges assembly gaps and lays a regular, rippled face on aluminium and on stainless steel.
• JOB program memory up to 999 numbers: you save proven settings for given parts and call them up by number.
• HOLD function: after the arc goes out the display holds the last real values of current and voltage, which makes quality control easier.
• Torch modes 2T, 4T and Super-4T plus spot and interval welding: Super-4T lets you steer the start and end current from the torch button, which helps on aluminium and with changing wall thickness.

Technical data

What you get

• Cloos Qineo Pulse 600 power source with a Master panel
• external Qineo WD Pulse wire feeder with a 4 roll drive
• interconnection cable 10 m
• MIG welding cable 4 m
• earth cable 4 m with a clamp
• supply cable 4 m

What to watch out for

The supply is 3 x 400 V at 50 or 60 Hz, the maximum input current 48.7 A and the effective one 37.8 A, so choose the connection and the fuse with a margin before installation. The open circuit voltage is 84 V, the protection class IP23 to EN 60974-1, that is work under a roof. A 60% duty cycle at 600 A and 44.0 V gives six minutes of welding in a ten minute window, and without a limit you work at 465 A and 37.5 V.

The source weighs over 200 kg, so for unloading and moving prepare a forklift and even ground. The interconnection cable 10 m long has to be routed with the bending radius kept, because current, gas, control and coolant run inside it, and too sharp a bend spoils the wire feed. The shop catalogue data give liquid cooling, so at the station you need a liquid cooled torch and fluid in the circuit, checked before the start.

You match the rolls, the liner and the contact tip to the diameter and the type of wire, and with aluminium you need U groove rolls and a teflon liner. The Master panel has ready synergic lines, but it is you who confirms which programs are active in this unit, so ask about the software configuration before you buy.

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.
