The machine supports MIG/MAG in manual, synergic, Pulse and Dual Pulse modes, as well as TIG Lift and MMA. This makes the XPro MIG 310 Dual Pulse suitable both for conventional welding of structural steel and for more demanding applications involving stainless steel or aluminium, where arc energy control, reduced distortion and high weld aesthetics are essential.

MIG/MAG welding – greater control, higher weld quality

The key working area of the SPARTUS XPro MIG 310 Dual Pulse is its advanced MIG/MAG process, designed for stable arc performance, fast configuration and high repeatability of results. The operator can work in manual mode, providing full freedom of settings, or use synergic programs that automatically select parameters according to material type, wire diameter and shielding gas.

The key advantage of the machine is the ability to work in Pulse and Dual Pulse modes. Pulse technology allows precise control of the amount of energy introduced into the material, resulting in a more stable arc, reduced spatter and better control of the weld pool. Dual Pulse additionally enables the characteristic aesthetic weld appearance similar to TIG welding, while maintaining the high productivity of the MIG/MAG process. This solution is particularly effective when welding aluminium and stainless steel, where limiting material overheating and controlling distortion are crucial for the final weld quality. Adjustment of pulse parameters, pulse frequency and base current allows the welding characteristics to be precisely adapted to the material type and technological requirements.

The machine offers advanced torch operation modes: 2T, 4T, S2T, S4T and SPOT. Classic 2T and 4T modes facilitate adaptation to short or long welds, while extended S2T and S4T modes allow control of the start and end of the process. This enables the operator to precisely manage arc ignition, starting current, final parameters and crater fill.

SPOT mode enables repeatable spot welds, improving precision when working on components requiring 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 improved process stability.

SPARTUS XPro MIG 310DP also offers detailed welding process control. The operator can adjust parameters such as pre-gas and post-gas flow, Soft Start, arc start and end parameters and Burn Back, responsible for proper wire feed termination. The Slow Feed function ensures controlled wire feeding start, improving ignition stability and operator comfort.

Synergic programs

SPARTUS XPro MIG 310 Dual Pulse offers synergic programs for the most commonly used materials and applications. The machine supports welding of mild steel, stainless steel, aluminium and self-shielded flux-cored wire. Thanks to the synergic function, the operator can start working faster and then fine-tune the parameters according to personal experience and specific joint requirements. It is a combination of automated settings with conscious process control.

Built-in 4-roll wire feeder

Stable wire feeding is crucial for MIG/MAG welding quality. SPARTUS XPro MIG 310 Dual Pulse is equipped with a built-in 4-roll wire feeder, ensuring smooth and uniform wire feeding.

The feeder is located inside the housing and is equipped with a practical inspection window and internal lighting, making it easier to monitor the spool, wire path and roller settings. This is particularly useful when changing wire, working in poorly lit areas and quickly checking the workstation before starting welding. Additionally, space for spare rollers in the feeder provides convenient access to the most commonly used accessories without the need to organise additional workspace.

The machine also supports a Spool Gun, increasing the possibilities of working with soft wires, especially aluminium. This solution improves feeding stability and reduces problems caused by guiding soft wire over a longer distance.

Electromagnetic compatibility (EMC)

XPro MIG 310 Dual Pulse 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 ensures reliable operation in environments with automation systems, robots and modern production installations.

20 memory channels – repeatability without wasting time

The machine offers 20 memory channels for saving 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 reconfigure all parameters. The result is shorter setup time, lower risk of errors and higher process repeatability.

User comfort and clear LCD panel

A modern control panel with a clear LCD display provides quick access to the most important functions and parameters. The interface guides the user through the selection of process, material, wire diameter and additional settings, making operation intuitive even with the machine’s advanced capabilities.
During welding, key operating parameters are displayed on the screen, allowing the process to be monitored continuously and adjusted quickly according to the requirements of a specific task.

TIG Lift Pulse – advanced parameter control

XPro MIG 310 Dual Pulse 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 310 Dual Pulse also supports TIG torches equipped with torch control and EURO connector.
