INDUSTRIAL POWER AND PRECISION – RELIABLE TIG AC/DC PULSE
The SPARTUS ProTIG 401PW AC/DC is a modern inverter welder designed for versatility and performance. It supports TIG AC/DC and MMA AC/DC welding with a maximum output of 400A, powered by a three-phase 400V supply.
TIG WELDING
The SPARTUS ProTIG 401PW AC/DC provides full control over the TIG AC/DC welding process. The operator can choose between convenient HF ignition and the Lift method, depending on the working conditions. The TIG Pulse function ensures stable welding of demanding materials – from thin sheets to aluminum components – while maintaining maximum precision.
The key adjustment options include:
• AC waveform shape – selection from three characteristics (square, sine, and triangular), allowing the arc energy to be matched to the material type and weld thickness.
• Advanced parameter settings – AC balance, AC frequency (50–250 Hz), as well as pulse frequency and width, ensuring optimal penetration and precise heat control.
• Arc dynamics control – adjustable upslope and downslope times enable a clean start and smooth finish of the weld.
• Spot modes – SingleSPOT and MultiSPOT functions support precise joining of components, especially useful in serial production and assembly work.
• Flexible operation – the choice of 2T or 4T modes allows the handling to be adapted to the intensity and duration of the welding cycle.
MMA WELDING
The SPARTUS ProTIG 401PW AC/DC also supports shielded metal arc welding (MMA), making it a versatile solution for both production workshops and fieldwork. The machine ensures a stable arc and high-quality welds across a wide range of materials, regardless of thickness.
Key MMA-supporting functions:
• AC and DC output – allows selection of the current type depending on the electrode and material being welded.
• Hot Start – facilitates arc ignition, reduces the risk of electrode sticking, and ensures a reliable start of the weld.
• Arc Force – stabilizes the arc under challenging conditions, minimizes spatter, and improves penetration control.
• Wide current range – up to 400A, suitable for assembly work with thin electrodes as well as welding thick structural components.
MOBILE WELDING CART
The SPARTUS ProTIG 401PW AC/DC is supplied as a set with an integrated cooler mounted on a practical welding cart. This convenient and functional configuration not only significantly improves the mobility of the entire system but also enhances cooling efficiency, which is crucial during extended welding sessions. Thanks to better heat dissipation, welders can work longer without the risk of equipment overheating, resulting in higher productivity and extended machine lifespan. Additionally, the mobility of the set allows for easy movement between different workstations, which is especially valuable in dynamic industrial environments.
COOLING
The SPARTUS ProTIG 401PW AC/DC offers a flexible cooling option, enabling operation with either gas cooling or an integrated cooler. Switching between modes is simple – just select the desired option on the control panel to adapt the cooling system to current needs and working conditions.
Memory channels – quick settings recall
The SPARTUS ProTIG 401PW AC/DC is equipped with an advanced memory system that allows up to 10 different welding configurations to be stored. This feature enables welders to switch quickly and easily between settings perfectly matched to various materials and working environments. As a result, users can significantly speed up their workflow, eliminating the need for constant manual adjustments. The ability to save favorite setups makes the SPARTUS ProTIG 401PW AC/DC not only efficient but also highly intuitive to operate, making it an ideal tool for professionals seeking both efficiency and precision in welding.
Control
The SPARTUS ProTIG 401PW AC/DC also stands out with its flexible control options, providing comfort and adaptability in various working environments.
