  • Superior aluminum performance - The upgraded pulse MIG has higher peak current and larger energy reserve. The precise control of pulse period ensures the stable process of droplet transition, and the perfect waveform achieves the heat control for aluminum welding.
  • High Speed Pulse (HSP) - The deposition rate can increase 25~48% for M.S. by comparing with MAG process.
  • High-Speed Spray Arc (HSA) - Highly concentrated and extremely stable arc with high density, up to 30% faster welding speed than conventional MIG-MAG welding.
  • Ultra Low Spatter (ULS) - It is a modified short-arc transfer arc, it controls the volatility during the change of state between short and arc to control the amount and size of the spatter generated. Up to 75% less spatter, up to 25% saving on gas costs.
  • High Speed Spot (HSS) - Offers a faster travel speed and better welding performance, especially for thin (less than 2mm) pipes or frame/structure welding jobs, like the furnitures etc.
  • Hybrid Pulse Control (HPC) - Mixes Pulse (spray arc) and short-circuit transfer types in one duty cycle. It great performance for all pipe welding solutions.
  • Micro Double Process (MDP) - Precise energy input, low distortion, perfect TIG-like welding appearance easily produced by anyone, and the welding productivity can up to twice as quick as the conventional TIG.
  • Easy to Use

  • Simple Operation
  • 3 steps To Achieve Weld Perfection

    1.Select operation mode.
    2.Select Processes-list No. (Welding process)
    3.Adjust welding current.
    (always the perfect setting by the synergic function using the material thickness)

  • Feature
  • Process-list

    To start welding, users can simply and quickly select a process No. according to any particular welding needs (based on material, process, gas, wire). A wide range of welding processes with perfect waves have been embedded into the well-displayed Topwell process-list.

    Synergy Control

    With the default synergy control, Topwell’s system can automatically synchronize the corresponding parameters based on the selected welding process and the adjusted current, which is easy and convenient for use. Users also can set the parameters manually when synergy is off.

    Memory Storage Function

    Users will have a variety of welding needs and hope to set the most suitable welding parameters for different materials and workpieces. Steelmate PRO Series has memory storage function, up to 999 independent welding tasks (Jobs) to maintain/save different welding operation parameters. Select and quickly restore previous settings with one click, making operation simpler and more efficient.

    Flexible control mothods

    you can regulate the machine everywhere ----- at the power source, at ....

    Ready for Intelligent Fabrication

  • MES and WeldNET Accessible
  • PROMIG XP Series is equipped with active user management and assigned NFC keys to set protection and permissions for parameter adjustment. It can also choose to connect to the MES system, which is more suitable for modern production data management.

    By connecting to Topwell WeldNET, you can pre-control the parameters, monitoring the process at real time, and trace the quality, thanks to the equipment, production, and process management modules. Meanwhile, your productivity and quality are boosted with analytic and statistical tools. It unleashes the potential of your future welding production.

  • Robot Welding Accessible
  • Robot interfaces are inserted via digital port (EtherNetlP, DeviceNet, CAN, CANOPEN, RJ485,etc.) with built-in communication protocols. No additional external communication modules are needed.

    Better Aluminum Welding Process

    The PROMIG XP Series is an upgraded model and machine that is compatible with more advanced pulse processes. Can provide a higher peak current and a larger current difference that is more suitable for aluminum alloy welding, easily triggering a stable arc and cleaning oxides, while generating enough heat to melt the metal and obtain high-quality welds.

  • Premium push-pull gun
  • Using the most durable motor and drive design, and installing the wire drawing motor close to the welding position, the wire feeding is smoother and less likely to get blocked, especially in aluminum welding conditions, which improves wire feeding performance and arc stability. 

    Equipped with LCD screen display and function keys, it can communicate with the power machine to adjust welding procedures and parameters. Communication between the digital welding torch and machine enables enhanced the synergy welding, as the wire speed increases/decreases, the MIG parameters increase/decrease to match the appropriate power required.

    The precise control of pulse period ensures the stable process of droplet transition, with only one drop of metal shooting out from the tip of the welding wire within a pulse period. Therefore, it will not generate a large amount of spatters, even under high current, reducing cleaning work and improving the appearance of the weld.

    The powerful data accumulation has shaped the perfect pulse waveform of PROMIG 500XP, with multiple welding parameters working together. As the wire speed increases/decreases, the pulse or MIG parameters will also increase/decrease to match the appropriate power required to achieve a more perfect welding curve.

    Refined Dip Transfer

    • Highly efficient dip transfer arc with refined waveform;
    • Suppress the spatter during short-circuit transition;

    • Create high-quality seams with increased deposition rate;
    • Spatter can be reduced by 20% when welding with CO2;

    The extension self-adjusting function maintains the stability of the same short arc length, enabling constant and regular short circuits, despite the change in the welding torch position, changing sheet thicknesses, or material misalignment.

    Benefiting from the wire feed control, the penetration stays stable and constant even in spite of the extension fluctuations.

    Advanced Technologies for Higher Efficiency

  • HSP (High Speed Pulse) - Ultra High Deposition Rate
  • Specifically designed for demanding workshop use, the deposition rate can increase 25~48 % for various materials, whether used in manufacturing thick materials or sheet metal.
    The High-Speed Pulse (HSP) process enables you to save time, money, and energy compared to traditional pulse welding. This process is ready to raise pulse welding to a whole new level!
    In general, One pulse melt one droplet, but we increase the submission of these droplets by TOPWELL’s new high speed pulse process. The transition will be faster, narrower HAZ zone and deeper penetration!

    Get better welding seam
    Less heat input, less spatters, less rework.

    Get higher welding strength
    Deeper penetration, no undercut defects, higher strength.

  • HSA (High Speed Spray Arc) - Superior Directional Property
  • The perfect combination of a highly concentrated and extremely stable arc with high density. HSA delivers deeper penetration, narrower heating zone, allows smaller opening angles for multi-layer welding, significantly improves the welding speed up to 30% faster than conventional MIG-MAG welding. It makes welding more efficient and more economical.

    Smaller opening angle

    Deeper penetration

    More material saving

    Higher welding efficiency

  • ULS (Ultra Low Spatters) - Stable and High Efficiency
  • The ULS process is a modified short-arc transfer arc with perfect waveform setting that greatly reduces spatter generation. In the pinch phrase, there is a special current interruption, the energy is extracted under the program setting, avoiding the explosion caused by the large current, and the surface tension of the molten pool warms the generated droplets. Even in CO2 and MAG welding, it can minimize the spatters, which means less rework, fewer rejects, less cleaning required and savings on wearing parts.

  • MDP (Micro Double Process) - TIG alike Results and Faster
  • MDP is micro double process, ultra-precise on the synergy pulse wave-form controlled process-control, freely adjust the weld seam chevrons from coarse to fine. The key is that when the high and low pulses alternate, there is no droplet formation in the low pulse phase. The advantage of MDP are precise energy input, low distortion, perfect TIG-like welding appearance easily produced by anyone, and the welding productivity can up to twice as quick as the conventional TIG. MDP is particularly suitable for thin to medium-walled (1-8mm) Aluminum, Steel, and CrNi applications, like frames, tables, beds, and furniture structures.
