For portability and versatility, a stud welder gun will be essential for any job requiring the use of these types of fasteners. There are three separate components to the system including the power supply, the cables, and the hand-held tool. The hand-held tool is the actual stud gun, with the system allowing for individual selection of the components.
There are also some options and models that come as complete systems with all three components supplied. Typically, most construction companies find the idea of being able to create the ideal system for their needs the best option.
Regardless of the complete or three-part system selected, there are some important considerations when comparing and evaluating different stud welder gun models.
Drawn Arc or Capacitor Discharge (CD)
Drawn arc stud guns are used for the larger diameter types of stud welds. They are also recommended with heavier workpieces or base metal components as they provide the rapid molten pool development and precision application of the stud to the molten pool.
For smaller diameter studs on lighter metal materials, the capacitor discharge (CD) systems are the best. Even with very thin base pieces, there will be no visible marring of the opposite surface.
Weight and Size
As most stud welder gun system will be used across a wide variety of settings, how easy they are to handle will be critical. This is true for building a bridge or working all day in fabrication.
Smaller and more lightweight systems still need to be durable and provide the features and functions needed for the job.
Durability and Lifecycle
Always take the time to learn about the manufacturer. Check their reputation for durable, rugged equipment that stands up to real-world working conditions. Specialized companies offering their own line of stud welders are an ideal place to start your search for tried and tested stud welders.
