Inverter Semi-Automatic Welding Machine SPARTUS XPro MIG 350 Dual Pulse

Industrial stability and full process control in a modern design

SPARTUS XPro MIG 350 Dual Pulse is a modern, inverter semi-automatic welding machine designed for users who expect high efficiency, a stable arc, and maximum control over the welding process. The three-phase 400V power supply, maximum welding current of 350A, and a 60% duty cycle provide an adequate power reserve for demanding workshop, production, and assembly work. The device performs perfectly both during classic structural steel welding and in more demanding applications involving stainless steel or aluminum, where precise control of the arc energy and weld aesthetics are crucial.

Advanced MIG/MAG Welding: Intelligent synergy and full control

The most important application area of the SPARTUS XPro MIG 350 Dual Pulse is the advanced MIG/MAG process, designed for a stable arc, quick configuration, and high repeatability of results. The operator can work in manual mode, providing full freedom of settings, or utilize synergistic programs that automatically select parameters based on the material type, wire diameter, and shielding gas.

The key advantage of the device is the ability to operate in Pulse and Dual Pulse modes. Pulsation technology allows for precise control of the energy introduced into the material, which translates into a more stable arc, fewer spatters, and better control of the weld pool.

Advanced management of arc cycle and operating modes

The SPARTUS XPro MIG 350DP provides the operator with a full set of parameters to optimize the process from the moment the trigger is pressed until the final crater filling:

• Full control of dynamic parameters: Regulation of Pre-gas and Post-gas, Soft Start, initial and final arc parameters, as well as Burn Back (wire burn-back control) guarantee clean ignition and an optimal weld bead finish.
• Slow Feed function: Provides a controlled, gentle start to the wire feed speed, which significantly improves ignition stability and increases overall working comfort.
• Inductance adjustment: Allows you to adapt the arc characteristics to the material and welding position (from a soft arc to a dynamic and concentrated one). This translates into excellent penetration control and enables braze welding (CuSi3).
• 2T / 4T / S2T / S4T modes: Classic control is enhanced with special S2T and S4T modes, which enable precise management of the starting current and final parameters for flawless crater fading.
• SPOT welding: Enables repeatable tack and spot welds thanks to accurate control over the welding pulse duration.
• Spool Gun compatibility: The ability to connect a dedicated torch with a mini-feeder in the handle eliminates wire feeding issues with soft aluminum wires over long distances.

Extended capabilities for TIG Lift and MMA methods

TIG Lift Pulse – Advanced thermal micro-control

The TIG Lift mode enables precise TIG DC welding with lift arc ignition, avoiding the use of high-frequency HF to protect surrounding sensitive electronics. The XPro series takes these capabilities a step further by offering the TIG Lift Pulse function with full adjustment of pulse frequency and width. The machine supports cooperation with advanced TIG torches equipped with handle controls and a EURO connector. This gives access to the extended 8T control cycle, which facilitates multi-stage processes and eliminates operator hand fatigue by removing the need to constantly hold down the trigger.

MMA Pulse – Intelligent current dynamics and constant power

The MMA process is supported by the MMA Pulse mode for more stable operation, alongside auxiliary systems: Hot Start (easier electrode ignition), Arc Force (arc stabilization in difficult positions), and the safe VRD module (reduction of open-circuit voltage). Two innovative operation characteristics are selectable:

• MMA Constant Current: Maintains a rigid, set current value regardless of fluctuations in arc length or hand position, guaranteeing a predictable and stable arc.
• MMA Constant Power: An intelligent algorithm balances voltage and current on the fly to keep the total arc power constant, automatically adjusting to the welding position.

Industrial innovations and daily working comfort

• Electromagnetic Compatibility (EMC): Full compliance with industrial standards; the device is resistant to external interference and safe for surrounding automation, robots, or control systems.
• 20 memory channels: Allows you to quickly save your own proven parameters. This shortens machine preparation time, eliminates adjustment errors, and guarantees perfect repeatability.
• Fan Stop system: Intelligent cooling control runs the fans only when necessary. This ensures silence at idle, saves energy, and limits dust extraction into the housing.
• Clear LCD panel: A modern and intuitive graphic interface efficiently guides you through the choice of material, wire diameter, and facilitates ongoing monitoring of key parameters.
• Increased operating range: The well-thought-out length of the cables (welding torch, ground cable, power cord, and a 3-meter gas hose with a quick coupler) ensures real freedom without constantly moving the welder.
• Extended warranty: The reliability of the equipment from the professional series is confirmed by a long protection period of up to 36 months.
