FAQ
Is X3 FastMig suitable for professional industrial welding?

X3 FastMig is a system-class welding machine designed for industrial welding, supporting professional and semi-skilled welders. The high-duty cycle, 60% ED power sources are designed and engineered for MIG/MAG welding, plus MMA and gouging processes.

Can I add a cooler to my X3 FastMig welding machine?

X3 FastMig offers both gas-cooled and water-cooled power sources. In water-cooled models, the cooler is integrated into the power source. You can select the specification that best suits your application, including an interconnection cable set suitable for either bench welding or welding at a distance from the power source.  

Can I fit a remote control to the X3 FastMig?

Yes, X3 FastMig supports torch-mounted GRe50 remote and handheld remote-control HR53.

Does X3 FastMig have any easy set-up techniques?

Yes, X3 FastMig allows both Manual and Auto set-up options. In Auto mode, select the filler wire type, diameter, and gas combination, then select the plate thickness to be welded. If you prefer to increase or reduce welding travel speed, you can dial in more or less power – it's really that simple.

How many standard welding programs does X3 FastMig have?

X3S power sources have more than 40 welding programs included when delivered from the factory, covering a wide range of filler materials and shielding gas combinations.

Brilliantly simple, brutally effective MIG/MAG welding

The X3 FastMig MIG/MAG welding machine is the quickest way to complete high-quality welds in difficult environments. With a robust design and durable wire feeder, the X3 FastMig can handle the bumps and bangs of heavy industrial MIG/MAG welding. It looks tough, but it's also simple and precise. A new icon-based user interface saves time with a fast setup and easy parameter selection. The X3 FastMig gives you immediate control over key functions for a simple and reliable way to create high-quality welds.

It's a brilliantly simple MIG/MAG welder that is also extremely powerful. When tasks get tougher, the X3 FastMig is always ready to meet heavy production targets. Need to complete the biggest job on site? No problem. With 420 amps at a 60% duty cycle, the X3 is brutally effective without compromising on quality. Lock in on a task and keep going until it's done. The X3 FastMig is perfect for industrial MIG/MAG welding, but it's also precise enough for simple welds that just need to be done quickly.

The X3 FastMig MIG/MAG welder comes with the X3 HD300 wire feeder, featuring a 4x4 wire drive mechanism and a strong plastic case with dual-wall construction. The X3 HD300 wire feeder can be attached to the X3 FastMig's MIG/MAG power source with a rotating plate. The safe-lift design allows the wire feeder to be lifted and suspended by the handle. Add a 4-wheel trolley or do more by adding accessories like a hanger for boom for the HD300 Wire Feeder. Adjust parameters while welding with the HR53 hand remote or GRe50 torch remote control which are available as optional accessories.
