VERSATILITY AND PRECISION IN ONE: THREE WELDING METHODS

• SMAW (Shielded Metal Arc Welding): The ideal solution for welding carbon steel, stainless steel, cast iron, and non-ferrous metals. The pulse current feature enables precise and efficient welding, even in challenging conditions.
• GTAW DC (Gas Tungsten Arc Welding): A precise arc welding method using inert gas shielding, perfect for tasks that demand the highest accuracy. The pulse current option allows for even greater control over the welding process.
• GMAW (Gas Metal Arc Welding): This CC/CV-capable device supports semi-automatic solid wire welding (MIG/MAG) or self-shielded welding (FCAW-S, FCAW-G) when connected to an external wire feeder. This transforms the PATON™ PRO 350 into a lightweight, portable modular machine that maintains high performance across a broad range of materials.

DESIGNED WITH YOU IN MIND

The PATON™ PRO-350 is a tool that makes every welding job simpler, more precise, and more comfortable. Features like adjustable Hot-Start, Arc-Force, and automatic Anti-Stick make starting the arc easier, provide greater control over the arc stability, and minimize electrode sticking across various electrode types. Together, these functions create a smoother, more efficient welding experience, even in the toughest conditions.

This compact unit is an excellent choice for professionals who need precise welding equipment for diverse industrial and workshop environments. Key to its efficient operation is maintaining a nominal current range of 16 to 18.5 A, which ensures optimal performance. The PATON™ PRO-350 is a dependable tool that rises to meet the demands of any welding challenge.

OPEN CIRCUIT VOLTAGE REDUCTION MODULE IN MMA MODE

The PATON™ PRO-350-400V model is equipped with an open circuit voltage reduction module, ensuring safe operation in demanding environments such as natural gas tank construction and maintenance tasks. This feature is critical in settings where high levels of electrical safety are essential. When the electrode is detached from the material, the module automatically reduces the voltage at the source terminals to a safe level below 12V within 0.1 seconds.

Designed for maximum versatility and user convenience, this welder allows for precise welding with electrodes featuring various coating types. The default slope of the current-voltage characteristic (CVS) is set at 1.4 V/A, which aligns well with common rutile and rutile-cellulosic electrodes like PATON™ 6013 ELITE, widely used in general construction, repair work, and welding of thin steel sheets.

To optimize welding conditions for basic-coated electrodes (e.g., PATON™ 7018 ELITE, PATON™ 7015 ELITE), it is recommended to adjust the CVS slope to 1.0 V/A. This increases arc stability and enhances weld quality. These electrodes are ideal for welding thick steel structures, bridges, and load-bearing components, where high joint strength is crucial.

For cellulosic-coated electrodes, the optimal CVS slope is between 0.2 and 0.6 V/A. Cellulosic electrodes, such as E6010 and E6011, are well-suited for challenging field conditions, where reliability and weld durability are key. The E6010 electrode, known for its deep penetration and stable arc, is particularly recommended for pipe welding and structural applications in the oil and gas industry, especially in vertical positions, including downhill welding. To further enhance arc stability, increasing the “Arc-Force” function to 18V is advised, providing better control and higher weld quality.

ADJUSTABLE HOT START PARAMETERS

Our technology ensures optimal arc ignition performance, guaranteeing reliable arc initiation even with electrodes that have low ignition potential. This achieves deeper and more uniform penetration of the base material right from the start, reducing the risk of damaging the workpiece. Additionally, this feature actively prevents slag inclusions during the welding process, resulting in a clean and durable weld.

ADJUSTABLE ARC FORCE PARAMETERS

The adjustable Arc Force parameters are essential for fine-tuning welding characteristics to meet specific material and task requirements. This function allows users to manually control arc force, providing two main benefits:

• Gentle Operations on Thin Materials: Lowering the Arc Force setting to its minimum is ideal for working with thin metals. This adjustment not only conserves energy and optimizes heat distribution but also minimizes the risk of burning through the material. It is worth noting that with this setting, arc stability may slightly resemble that of traditional transformer-based sources.
• Enhanced Arc Stability: For tasks requiring exceptional arc stability, the Arc Force setting can be increased to its maximum level. This configuration provides excellent stability for a short arc, which is crucial for achieving high-quality welds. However, it requires a robust power supply and may slightly increase the risk of burn-through on the material.

DURABLE WELDS, CRAFTED WITH PRECISION

The pulse welding technology by PATON International, which includes both the GTAW LIFT and SMAW PULSE methods, ensures exceptional durability and strength of the weld.

TIG LIFT PULSE

This technique enables precise welding with controlled arc ignition by touching the tungsten electrode to the material and then lifting it (LIFT). When the device detects this movement, it interprets it as a signal to initiate the welding process, resulting in a linear increase in welding current up to the preset value. The pulsing function in this method regulates the welding current in pulses, allowing for precise heat input control and preventing material overheating. This approach allows for high-quality welds, particularly when welding thin materials or in challenging welding positions.

SMAW PULSE AND SHORT ARC: STABLE ARC AND IMPROVED CONTROL

In the context of welding with the SMAW PULSE method, minimizing the risk of short circuits is one of the key advantages of the pulsating welding current.

During pulse welding, two current levels are employed: the base current (lower) and the pulse current (higher). The base current is maintained for most of the duration, serving to stabilize the arc, while the pulse current is applied in short bursts, facilitating the transfer of molten metal droplets from the electrode to the weld pool.

SHORT ARC Technology

SHORT ARC technology significantly enhances stability during welding with minimal electrode-to-workpiece distance. This feature is especially effective in tasks requiring delicate and precise arc control, which is crucial when welding thin sheets or intricate components. It provides superior control over the weld pool, reducing spatter and facilitating welding in various positions, such as overhead work or vertical welding. The result is typically shallow penetration, a stable arc, and cleaner welds. However, it is essential to select the appropriate electrodes to achieve optimal results.

VOLTAGE STABILIZATION, LONG EXTENSION CORD SUPPORT, AND GENERATOR OPERATION

The PATON™ PRO 350 inverter welder is equipped with a voltage drop protection system, enabling optimal performance at a nominal current of 350A, even under demanding conditions. The unit maintains its efficiency when powered through long extension cords, such as up to 100 m with a cross-section of 4 mm² or up to 65 m with a cross-section of 2.5 mm², as well as during generator operation.

The PATON™ PRO 350 can be powered by various types of generators, provided they meet the required technical specifications. Generators equipped with Automatic Voltage Regulation (AVR) or equivalent systems and rated power in line with the user manual are especially recommended. It is essential that the generator’s output voltage falls within the range of 340V – 460V to ensure smooth and safe operation of the device.

For welding with coated electrodes up to Ø6 mm, TIG welding with tungsten electrodes up to Ø3.2 mm at a nominal current of 350A, or MIG/MAG welding with solid wire up to Ø1.4 mm, a minimum generator power of 16.0 kVA is recommended.

Alternatively, for solid wire welding up to Ø1.0 mm and coated electrodes up to Ø5 mm at currents up to 200A, a generator power rating of 7.7 kVA will be sufficient.

INTEGRATED WELDING PARAMETER MEMORY: FASTER SETUP AND ENHANCED EFFICIENCY

Our welding unit allows for the storage of up to 16 programs in each mode: SMAW, GTAW, and GMAW. Upon startup, it automatically loads program number 1, and any changes to settings are saved instantly. With a simple one-button program switch, you can quickly return to preferred settings, minimizing downtime. The unit’s memory enables storing parameters for different tasks, reducing preparation time and optimizing the welding process.

WIRED REMOTE CONTROL – REMOTE CONTROL IN MMA (MANUAL METAL ARC) WELDING

Remote control in MMA (Manual Metal Arc) welding refers to the ability to adjust welding parameters from a distance during the welding process. This type of system is valuable in various welding scenarios, particularly where the operation is conducted in hard-to-reach or hazardous locations. Remote control technology allows operators to adjust parameters, such as current intensity, without needing to approach the welder. This option is available upon request.

FAN STOP DYNAMICS AND ERGONOMIC BODY ENGINEERING

PROTECTION CLASS IP33

The welder’s housing is rated IP33, which means it is protected against the ingress of foreign objects larger than 2.5 mm in diameter and against water droplets falling at an angle of up to 60° from the vertical. This level of protection ensures safe and efficient operation during light rain or accidental splashes. However, caution should still be exercised, as welding during heavy rain can increase the risk of electric shock, particularly on damp working surfaces.

ADVANCED COOLING SYSTEM

The unique design of the welder’s housing and optimized airflow through the cooling chamber significantly extend the lifespan of components, durability, and duty cycle, even in highly dusty production environments. Additionally, the device features an advanced adaptive fan speed control system, where the fans automatically stop when the welder is in idle mode.
