INDUSTRIAL TIG DC WELDER WITH PULSE
The SPARTUS ProTIG 321PW DC is a modern inverter welder based on IGBT technology and pulse width modulation (PWM). This high-class power source, delivering up to 320A and powered by a three-phase 400V supply, has been designed for intensive production and industrial applications.
TIG welding
The machine supports the TIG DC process, providing precise control over welding. The operator can adjust key parameters such as:
• upslope and downslope time,
• start and end current,
• pre-gas and post-gas,
• 2T/4T modes and SPOT mode.
The TIG Pulse function allows adjustment of pulse current, base current, frequency (0.5–999Hz), and pulse width (5–95%). This makes the welder an excellent choice for welding very thin sheets, ensuring high quality and aesthetic welds.
MMA welding
The SPARTUS ProTIG 321PW DC also enables covered electrode welding in MMA DC mode. The operator has access to supportive functions: Arc Force (0–10) and Hot Start (0–10), which improve arc stability and facilitate electrode ignition.
MOBILE SET ON A WELDING CART
The SPARTUS ProTIG 321PW 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 set but also increases cooling efficiency, which is crucial during longer welding sessions. With improved heat dissipation, welders can work longer without the risk of equipment overheating, resulting in higher performance and extended service life of the machine. Additionally, the mobility of the set allows for easy movement between different workstations, which is especially valuable in dynamic industrial environments.
Memory channels – quick recall of settings
The SPARTUS ProTIG 321PW DC is equipped with an advanced memory system that allows saving up to 10 different welding configurations. This function enables welders to quickly and easily switch between various settings, perfectly adapted to the specifics of working with different materials and in diverse environments. As a result, users can significantly speed up their workflow, eliminating the need for constant manual parameter adjustments. The ability to store favorite settings makes the SPARTUS ProTIG 321PW DC not only efficient but also highly intuitive to operate, making it an ideal tool for professionals seeking efficiency and precision in welding.
COOLING
The SPARTUS ProTIG 321P DC offers a flexible cooling option, allowing operation with either gas cooling or the integrated cooler. Switching the mode on the control panel is all it takes to adjust the cooling system to current needs and working conditions.
Control
Operation is carried out via a modern function panel with an LCD display. All parameters are smoothly and steplessly adjustable, allowing full control over the process. Additionally, the machine is compatible with both wired and wireless remote controls, including a foot pedal, which enhances user comfort.
