How to Choose the Right Double Gun Stud Welder
Choosing the right double gun stud welding machine depends on the required stud diameter, welding mode, and available power supply. The RSN7 series offers four models with different single-gun and dual-gun capacities to meet various steel construction and industrial fabrication needs.
Check Stud Diameter
Determine the maximum stud diameter required for simultaneous dual-gun welding. RSN7 models support Ø18-28 mm per gun in dual-gun mode, depending on the model.
Select the Welding Mode
Choose between single-gun and simultaneous dual-gun operation based on your workflow. Single-gun mode supports larger stud diameters, while dual-gun mode allows two operators to weld at the same time.
Verify Power Requirements
Check the available input voltage, power capacity, and project workload before selecting a model. Customized voltage options are available to meet different regional power requirements.

Single-Gun vs Dual-Gun Stud Welding: Which Setup Works Best?
The RSN7 double gun stud welding system supports both single-gun and simultaneous dual-gun operation. Single-gun mode provides greater welding capacity for larger studs, while dual-gun mode allows two operators to work simultaneously for improved productivity on large projects.
Single-Gun Operation
Higher Welding Capacity
Supports larger stud diameters using the machine’s full single-gun welding capacity.
One Welding Operator
Ideal for projects requiring one active welding gun and controlled operation.
Large-Diameter Studs
Suitable for heavy-duty stud welding tasks that require larger diameters and higher welding currents.
Dual-Gun Operation
Simultaneous Welding
Two independent welding guns can operate simultaneously from one machine.
Two Welding Operators
Supports parallel welding tasks to improve overall project efficiency.
Higher Workflow Efficiency
Ideal for repetitive welding tasks within the machine’s dual-gun capacity.
Note: Welding current and stud diameter limits vary between single-gun and dual-gun modes. Refer to the RSN7 model specifications for detailed capacities.

RSN7 Dual-Gun Stud Welder FAQs
Find answers about RSN7 dual-gun operation, welding capacity, model selection, and power requirements to help you choose the right stud welding system.
Yes. RSN7 double gun stud welders use independent inverter circuits to support simultaneous operation of two welding guns from one machine. Each gun operates within the specified dual-gun welding current and diameter limits.
Single-gun mode supports larger stud diameters and higher welding current. For example, the RSN7-5000-2 welds studs up to Ø38 mm in single-gun mode, compared with Ø28 mm per gun during simultaneous dual-gun operation.
The RSN7-4000-2 supports studs up to Ø24 mm per gun, while the RSN7-5000-2 supports up to Ø28 mm per gun during simultaneous operation. Both models meet the Ø22 mm diameter requirement, subject to application conditions.
Yes. The RSN7 series supports both operating modes. Single-gun operation provides higher welding capacity for larger studs, while dual-gun operation allows two operators to weld simultaneously within the machine's specified limits.
Standard RSN7 models are specified for AC 380V ±15%. Customized input voltages, including 415V, 440V, and 460V, are available upon request. Please confirm your site's electrical requirements before ordering.
RSN7 machines feature independent inverter modules, allowing maintenance of individual welding channels. Depending on the fault, the remaining channel may continue operating after a safety assessment by a qualified technician.
