SPARTUS XPro MIG 310 Dual Pulse Inverter Welder

Compact Dual Pulse power and industrial performance driven by a heavy-duty 400V three-phase supply

The SPARTUS XPro MIG 310 Dual Pulse is a state-of-the-art inverter semi-automatic welding machine engineered for professionals who demand maximum efficiency, advanced welding functions, and effortless portability. Housed in a remarkably compact chassis and powered by a three-phase 400V supply, this heavy-duty unit delivers a massive welding current of 300A at a high 60% duty cycle. It provides an exceptional power reserve tailored for everything from intensive industrial manufacturing to highly demanding workshop fabrication, assembly, and on-site field maintenance.

Advanced MIG/MAG Welding: Intelligent Synergy & Ultimate Control

Designed for absolute process reliability, the MIG/MAG mode allows operators to work in Manual mode for complete configuration freedom, or utilize advanced Synergic programs. Synergy automatically calculates optimal parameters based on the material type, wire diameter, and shielding gas, allowing you to start welding instantly while retaining the ability to fine-tune settings based on job specifications.

The core technological advantage of the XPro MIG 310 lies in its full support for Pulse and Dual Pulse modes. Pulsation stabilizes the arc, drastically minimizes weld spatter, and manages the precise amount of thermal energy introduced into the metal pool.

Comprehensive Arc Cycle Management & Torch Modes

The SPARTUS XPro MIG 310DP puts comprehensive parameters at the operator's disposal to optimize the process from the initial trigger pull to final crater filling:

• Full Gas and Wire Management: Adjustable gas pre-flow (Pre-gas) and post-flow (Post-gas), Soft Start, Slow Feed (controlled initial wire crawl), and Burn Back control guarantee clean arc starts and perfect endings without wire-to-tip sticking.
• Inductance Control: Adjusts the arc characteristics (soft/hard) to optimize penetration and minimize spatter, making it indispensable for high-quality MIG brazing (CuSi3).
• 2T / 4T / S2T / S4T Trigger Modes: Standard torch controls are augmented with specialized advanced cycles (S2T and S4T), allowing operators to program a specific starting current and crater-fill sequence to eliminate end-weld craters.
• SPOT Welding: Enables uniform, time-controlled spot and tack welds for high-speed repeat assembly.
• Spool Gun Compatibility: Connecting an optional spool gun with an on-torch mini-feeder completely eliminates the risk of wire nesting or feeding issues when running soft aluminum wire over longer distances.

Available Synergic Programs:

Expanded TIG Lift and MMA Multi-Process Performance

TIG Lift Pulse – Advanced Thermal Micro-Control

The unit delivers high-precision TIG DC welding using Lift arc ignition (touch start, completely free of HF high-frequency radio interference). The XPro series elevates touch-start TIG by introducing TIG Lift Pulse, complete with adjustable pulse frequency and width parameters. This enables meticulous heat management on ultra-thin gauges. Additionally, the welder natively supports specialized TIG torches equipped with remote handle controls and a unified EURO connector. This unlocks standard 2T/4T modes alongside an advanced 8T trigger cycle, reducing operator hand fatigue during complex, multi-stage production welds.

MMA Pulse – Smart Current and Constant Power Dynamics

Stick electrode welding up to 250A is reinforced with a heavy-duty MMA Pulse mode, alongside automated welding aids: Hot Start (easier arc ignition), Arc Force (arc stabilization in tight positions), and a VRD safety module (Voltage Reduction Device). To suit highly critical jobs, operators can toggle between two advanced output curves:

• MMA Constant Current: Locks in a perfectly stable current value regardless of fluctuations in arc length, ensuring an entirely predictable, uniform weld bead deposit.
• MMA Constant Power: An intelligent real-time algorithm dynamically balances voltage and current to keep total arc power static. The machine seamlessly adapts itself to changing manual positions.

Industrial Innovations and Operational Comfort

• Electromagnetic Compatibility (EMC): Fully compliant with industrial electronics standards; the machine is completely resistant to external interference and will not disrupt automated hardware, automated cells, or robotics.
• 20 Memory Channels: Instantly save and recall your custom parameter configurations, slashing setup times to zero and eliminating setup errors.
• Fan Stop System: Smart on-demand cooling regulates internal fans to activate only under heavy loads. This yields quiet idle periods, saves power, and minimizes the intake of metallic grinding dust into sensitive components.
• Crisp LCD Display: An intuitive, high-visibility user interface dynamically tracks and displays live welding current and voltage values during operation.
• Extended Workplace Reach: The heavy-duty package includes a 3-meter MIG welding torch, work/ground clamp, power cable, and a 3-meter gas hose equipped with a quick-connect coupling for uninhibited maneuvering.
• Robust Industrial Build: Rated at IP21S protection, the chassis stands firmly on robust feet, but can easily be equipped with the included wheel kit for maximum workspace agility.
