ARC WELDING INVERTER EQUIPMENT (PRO-I 1300)

SHORT ARC AND DRAWN ARC WELDING EQUIPMENTS

INVERTER TECHNOLOGY FOR HIGH ARC STABILITY

The inverter arc welder (PRO-I 1300) for studs, including Nelson-type, and internally threaded bushings, with microprocessor control, ensures excellent welding quality. The advanced inverter technology guarantees precise control, high process repeatability, and maximum arc stability, even with short welding times and low currents.

With a high welding capacity (up to Ø13 mm) and an innovative cooling system, it enables intensive work cycles and fast welding operations. Its reduced weight compared to traditional units makes it ideal for mobile applications. The integrated electronic power supply operates over a wide voltage range (320-495V), ensuring reliable performance even with unstable power sources, such as long extension cables or generators. Its robust construction allows operation in demanding environments.

The inverter arc welder (PRO-I 1300) comes standard with the PowerPackage system, an intelligent solution that allows multiple units to be connected, achieving a welding power of up to 3150A. By linking two (or optionally three) PRO-I inverter welders, a high-power unit can be created.

Designed for short arc and drawn arc stud welding, it offers continuous adjustment of welding current and time, with automatic constant current control. The user-friendly interface includes a robust rotary switch and a large display showing all functions and operational parameters. Pre-installed welding programs simplify parameter selection, with the option to store custom settings.

Its modular design allows customization to meet specific user requirements, with configurable optional functions. The integrated monitoring system ensures quality control, automatically storing parameters for the last ten welds. Additionally, an optional extended memory enables the storage of up to 24,500 cycles, with a USB interface for data transfer to a PC.

The inverter arc welder (PRO-I 1300) can be equipped with a gas protection module for the welding gun and an automation system that includes a VBZ automatic feeder and an automatic welding gun. For simultaneous operation of up to four welding guns on a single unit, with independent current and time settings, the external PRO-SPLIT adapter generator is available as an accessory, automatically detecting the active gun.

FAQ and insights

Drawn arc stud welding is a process used to securely join a metal threaded stud to a metal surface. It is widely used in industrial applications because it creates strong, reliable, and long-lasting connections.

The process is carried out using a dedicated welding system equipped with a welding gun. When activated, the gun generates an electric arc that melts both the tip of the stud and the surface beneath it at the same time.

This creates a weld pool, which is held in place by a ceramic ferrule. The ferrule helps contain the molten metal and ensures a clean, consistent weld, resulting in a high-quality and durable joint.

In the long arc cycle welding process, the welding stud or pin is joined by an electric arc that generates enough heat to melt both the base material and the fastener. The resulting molten pool is either contained by a ceramic ferrule or left exposed and protected by an inert gas, which is automatically supplied through a protective positioner mounted on the welding gun.

Short arc cycle welding, on the other hand, produces the electric arc in just a few milliseconds. Because of the extremely short welding time, much less material is melted compared to the long arc process. This method is ideal for welding threaded studs up to M8 on thin sheet metal, minimizing heat input and reducing the risk of distortion.

The key elements for achieving a high-quality weld include careful surface cleaning, the selection of the correct equipment that A.T.S. Lamberti normally recommends to the customer, the proper adjustment of welding parameters, and the use of certified drawn arc welding studs.
