About PRO WELD

PRO WELD is a manufacturer of stud welding equipment and consumables, with a product line that includes drawn arc stud welders, collets, and stop pins. The brand's equipment is used in metal fabrication, construction, shipbuilding, and other industries where studs are welded to metal surfaces. 3G Electric supplies PRO WELD products globally, offering technical buyers access to both power units and the replacement parts needed to maintain them.

The PRO WELD portfolio covers two main categories: stud welding power supplies and stud welding accessories. The power supply line includes the ARC 1200 HD, a three-phase drawn arc stud welder rated for studs up to 5/8 in diameter. It operates on 230/460/575V input at 50/60 Hz, making it suitable for high-production environments where consistent weld quality and duty cycle matter. This unit is designed for drawn arc welding, a process that uses a ceramic ferrule and a controlled arc to join studs to a base metal.

The accessory line includes B stud welding collets and stop pins. Collets are made of copper and are sized to specific stud diameters, including #6 (10 ga), #10 (5 mm), 1/8 in, and 5/16 in. They accommodate stud lengths from 1/4 in to 1 1/4 in. Stop pins are made of steel and are used to set stud insertion depth; they are available for various stud lengths, such as 1/4 in, 1/2 in, and 1 1/4 in. These consumables are critical for maintaining weld consistency and are typically replaced as they wear.

For plant engineers and maintenance managers, PRO WELD products offer a practical combination of power and precision. The ARC 1200 HD's three-phase input and voltage range allow it to be integrated into industrial power systems without additional transformers in many cases. The collets and stop pins are straightforward replacement items that help minimize downtime when they reach the end of their service life. 3G Electric supports the PRO WELD line by stocking these components and providing specification details, such as stud diameter compatibility and material composition, so buyers can match parts to their existing equipment. This reduces the risk of ordering incorrect consumables and helps maintain welding quality across production runs.

3G Electric's role is to make PRO WELD equipment and parts accessible to a global customer base. The company provides product data, including manufacturer part numbers and key dimensions, to assist procurement specialists in identifying the correct items. Whether the requirement is a complete stud welding system or replacement collets and stop pins, 3G Electric serves as a source for PRO WELD products.

Common Applications

  • Metal fabrication — PRO WELD ARC 1200 HD drawn arc stud welder for attaching studs up to 5/8 in diameter to steel plates and structures.
  • Construction — PRO WELD B stud welding collets and stop pins for welding shear connectors and anchors to beams and columns.
  • Shipbuilding — PRO WELD drawn arc stud welder for fastening studs to deck plates and hull sections in high-production environments.
  • Industrial maintenance — PRO WELD replacement collets (e.g., CDB-013) and stop pins (e.g., 033-781) to keep stud welding equipment operational.
  • Automotive assembly — PRO WELD stud welding consumables for welding studs to chassis and body panels where consistent weld quality is required.
  • Heavy equipment manufacturing — PRO WELD ARC 1200 HD for welding large-diameter studs to frames and components in fabrication shops.

Frequently asked questions

Common questions about PRO WELD from 3G Electric.

What stud diameters can the PRO WELD ARC 1200 HD drawn arc stud welder handle?

The PRO WELD ARC 1200 HD is rated for a maximum stud diameter of 5/8 in. It is a three-phase drawn arc stud welder that operates on 230/460/575V input at 50/60 Hz. This makes it suitable for welding studs up to that diameter in high-production settings. For smaller studs, the same unit can be used with appropriate collets and stop pins. The welder is designed for drawn arc welding, which requires a ceramic ferrule and provides a strong, consistent weld. When selecting studs, ensure the diameter does not exceed the rated maximum to avoid equipment damage or poor weld quality.

What is the difference between a PRO WELD collet and a stop pin?

A PRO WELD collet is a copper component that holds and aligns the stud during welding. It is sized to a specific stud diameter, such as #6 (10 ga), #10 (5 mm), 1/8 in, or 5/16 in, and accommodates stud lengths from 1/4 in to 1 1/4 in. A stop pin is a steel component that controls the insertion depth of the stud, ensuring consistent weld penetration. Stop pins are matched to stud length, for example, 1/4 in, 1/2 in, or 1 1/4 in. Both are consumables and are replaced as they wear. Using the correct collet and stop pin for the stud being welded is essential for proper alignment and weld quality.

Are PRO WELD B stud welding collets compatible with other brands of stud welders?

PRO WELD B stud welding collets are designed for B stud welding applications, which is a common stud welding system. Compatibility with other brands depends on the specific welder's collet holder and the stud geometry. The collets have a specific outer diameter and thread that must match the welding gun. PRO WELD collets are identified by manufacturer part numbers such as CDB-012, CDB-013, CDB-018, and CDB-031. To ensure compatibility, check the stud welder's manual for the required collet specifications or consult the equipment manufacturer. Using a collet that does not properly fit can result in poor weld alignment or damage to the welding gun.

What materials are PRO WELD stop pins made of?

PRO WELD stop pins are made of steel. They are designed to withstand the mechanical forces during stud welding and to maintain their dimensions over repeated use. The steel construction provides durability and resistance to deformation, which is important for consistent stud insertion depth. Stop pins are available for various stud lengths, such as 1/4 in, 1/2 in, and 1 1/4 in, with overall lengths matched to the application. For example, part number 033-781 is for 1/4 in stud length with a 1 1/4 in overall length, while 033-783 is for 1/2 in stud length with a 1 in overall length. Regular inspection and replacement are recommended to maintain weld quality.

Can 3G Electric provide PRO WELD collets for a specific stud diameter?

Yes, 3G Electric supplies PRO WELD collets for a range of stud diameters, including #6 (10 ga), #10 (5 mm), 1/8 in, and 5/16 in. Each collet is identified by a manufacturer part number, such as CDB-013 for #6, CDB-018 for #10, CDB-012 for 1/8 in, and CDB-031 for 5/16 in. These collets accommodate stud lengths from 1/4 in to 1 1/4 in. To order the correct collet, specify the stud diameter and the welder model. 3G Electric provides product specifications and part numbers to help buyers match the collet to their equipment. For custom requirements, contact 3G Electric with the stud details.
