SPARTUS XPro MIG 300
– industrial stability, synergy, and full process control
SPARTUS XPro MIG 300 is a modern inverter welding machine designed for users who expect high performance, a stable arc, and repeatable results in everyday workshop and industrial applications. 400V three-phase power supply, maximum welding current of 300A, and 60% duty cycle provide a solid power reserve for demanding production, assembly, and service tasks.
The machine supports MIG/MAG processes in manual and synergic modes, as well as TIG Lift and MMA. This makes the XPro MIG 300 a versatile welding center — from classic steel welding, through stainless steel and aluminium, to coated electrode welding and TIG welding.
MIG/MAG welding – performance, stability, and arc control
The main working area of the SPARTUS XPro MIG 300 is the MIG/MAG process, designed for fast parameter setup, stable arc control, and high weld repeatability. The user can work in manual mode, which provides full setting freedom, or use synergic programs, which significantly speed up machine configuration.
Synergy allows faster adjustment of parameters to the material, wire diameter, and shielding gas, reducing the risk of incorrect settings. This is especially important in workshop and production work, where not only weld quality matters, but also setup time and repeatable results on subsequent components.
The machine offers advanced gun operating modes: 2T, 4T, S2T, S4T, and SPOT. Classic 2T and 4T modes make it easier to adapt operation to short or long welds, while the extended S2T and S4T modes allow control over the start and end of the process. This enables the operator to precisely manage arc ignition, start current, final parameters, and weld crater filling.
SPOT mode enables repeatable spot welds, increasing accuracy when working with components that require welding time control. Inductance adjustment allows the arc characteristics to be adapted to the material and welding position — from a softer arc to a more dynamic and concentrated one. In practice, this means better penetration control, reduced spatter, and greater process stability.
SPARTUS XPro MIG 300 gives the user access to detailed welding process control. The settings menu allows adjustment of, among others, pre-flow and post-flow gas time, Soft Start, and arc start and end parameters.
The Slow Feed function controls slow wire feeding during start-up, making stable arc ignition easier and reducing the risk of process instability. Burn Back ensures proper wire feeding termination, reducing the risk of the wire sticking to the weld pool or contact tip. These functions have a real impact on working comfort and weld finishing quality.
Synergic programs
SPARTUS XPro MIG 300 offers synergic programs for the most commonly used materials and applications. The machine enables work with carbon steel, stainless steel, aluminium, and self-shielded flux-cored wire, among others. Thanks to synergy, the operator can start work faster and then fine-tune the parameters according to their own experience and the requirements of a specific joint. It is a combination of automated settings and conscious process correction.

Built-in 4-roll wire feeder
Stable wire feeding is crucial for MIG/MAG welding quality. SPARTUS XPro MIG 300 is equipped with a built-in four-roll wire feeder that ensures smooth and consistent wire feeding.
The feeder is located inside the housing and features a practical inspection window and internal lighting, making it easier to monitor the spool, wire guidance, and roller settings. This is especially useful during wire replacement, when working in poorly lit areas, and for quick workstation inspection before welding. Additionally, the storage space for spare rollers inside the feeder provides convenient access to the most commonly used accessories without the need for additional workspace organization.
The machine also supports a Spool Gun torch, increasing capabilities when working with soft wires, especially aluminium. This solution improves feeding stability and reduces issues caused by guiding soft wire over longer distances.
Electromagnetic compatibility (EMC)
SPARTUS XPro MIG 300 features high electromagnetic compatibility (EMC), ensuring stable operation without interference in demanding industrial environments. The machine has been designed not to affect the operation of other machines and control systems while maintaining resistance to external interference. This guarantees reliable performance in environments with automation systems, robots, and modern production installations.
20 memory channels – repeatability without wasting time
The machine offers 20 memory channels for storing custom welding parameter settings. This is a major advantage when working with repetitive components, different materials, or recurring production tasks. The operator can save proven configurations and quickly recall them without having to reset all parameters each time. The result is shorter setup time, reduced risk of errors, and higher process repeatability.
Comfortable operation and clear LCD panel
The modern control panel with a clear LCD display provides quick access to the most important functions and parameters. The interface guides the user through process selection, material type, wire diameter, and additional settings, making operation intuitive even with the machine’s advanced capabilities.
During welding, the screen displays key operating parameters, allowing continuous process monitoring and quick adaptation to the requirements of a specific task.
TIG Lift Pulse – advanced parameter control
SPARTUS XPro MIG 300 is not limited only to MIG/MAG welding. TIG Lift mode enables precise TIG DC welding with touch arc ignition, without the use of HF high frequency. This is a practical solution wherever greater process control and high weld aesthetics are required.
However, the XPro MIG series takes TIG Lift capabilities a step further. The machine is equipped with an advanced TIG Lift Pulse function with pulse operation mode and access to extended welding process settings, including pulse frequency and pulse width adjustment. This solution allows even more precise control of the welding arc, heat input and weld characteristics, which will be particularly appreciated by users working with thinner materials or demanding components.
In addition to standard support for TIG torches with a gas valve, SPARTUS XPro MIG 300 also supports TIG torches equipped with torch control and EURO connector. This allows the operator to conveniently control the welding process without removing their hand from the torch, significantly improving comfort and ergonomics. Additionally, in this configuration, besides 2T and 4T modes, the machine also offers an 8T mode, enabling an extended torch control cycle. This solution improves operation during multi-stage welding processes and reduces the need to continuously hold the torch button, increasing operator comfort.
MMA Pulse and intelligent process control
SPARTUS XPro MIG 300 offers an advanced MMA Pulse process, providing even greater control of the welding arc, improved stability and better adaptation of welding characteristics to working conditions and operator preferences. Additionally, the machine is equipped with functions supporting comfort and weld quality such as: Hot Start – facilitating electrode ignition, Arc Force – stabilising the arc during welding, VRD – increasing safety by reducing no-load voltage.
The XPro MIG series additionally offers two advanced MMA characteristic modes: constant current and constant power.
MMA Constant Current — stable and predictable arc
In MMA Constant Current mode, the machine maintains a stable welding current value regardless of changes in arc length or working conditions. This solution ensures high process stability, facilitates electrode handling and enables repeatable weld quality. Automatic maintenance of the set current value reduces the need for continuous parameter correction by the operator, improving comfort and simplifying welding process control.
MMA Constant Power — intelligent parameter adjustment
MMA Constant Power mode dynamically adjusts output voltage and current to maintain constant welding power. As a result, the machine automatically adapts operating characteristics to changes in arc length and process conditions. This solution increases welding stability, simplifies operation and allows faster adjustment of working parameters to different materials and welding positions. The operator sets the required power, and the machine automatically optimises the remaining process parameters.
Stable trolley and work-ready design
SPARTUS XPro MIG 300 is mounted on a stable transport trolley with space for a gas cylinder. This design makes workstation organization, machine movement, and work in different areas of the workshop or production hall easier.
The IP23S protection rating increases the machine’s resistance to demanding operating conditions, while the robust housing and well-thought-out component layout make the XPro MIG 300 ready for intensive everyday work.
An additional advantage of the machine is the intelligent Fan Stop cooling control system, which activates the fan only when necessary. This results in quieter operation, reduced contamination intake, and extended component lifespan.
Greater working range, fewer limitations
The thoughtfully designed cable configuration – 3-meter welding gun, work clamp, and power cable – provides real freedom of movement when working on large components and reduces the need for frequent repositioning of the machine. The 3-meter gas hose with quick connector speeds up setup and improves workstation organization, increasing overall work efficiency.
