What Is a Handheld Induction Brazing Machine?
A handheld induction brazing machine is a portable induction heating system that uses a lightweight remote heating head and custom induction coil to braze copper, brass, steel and other metal joints directly at the workpiece.

Main Application Advantages
The DWS series is designed for situations where the component cannot conveniently be moved. The generator remains away from the workpiece while the operator positions the compact heating head and coil around the joint.
Key advantages include localized heat, no direct flame, flexible coil design, easier access to difficult joints, reduced heating of surrounding components and suitability for both field maintenance and industrial production.
Applications：
Induction Brazing small parts, selective heat treatment, and induction heating in areas requiring a smaller, moveable unit. Used for induction brazing on site such as the induction brazing of copper cable connectors, copper joints in the air conditioner, copper connectors of the transformer and so on.
Characteristics：
- By special design, the handheld induction brazing head is small sized and only weights 1.5 to 8 KG, it is especially suitable for the operation on working site when the heated parts can not be moved.
- The handheld induction heater is characterized with high reliability and high quality while the IGBT power module and our third generation inverting technology is adopted in the induction heating machine.
- The induction heating coil will be designed according to your requests.
FAQs
1. What is a handheld induction brazing machine used for?
A handheld induction brazing machine is primarily used for localized brazing and heating where the component is large, fixed or difficult to move.
Typical applications include HVAC copper tubes, refrigeration lines, copper cable connectors, transformer terminals, pipe fittings and selective industrial heating.
2. What power ranges are available for HLQ handheld induction brazing machines?
HLQ currently lists four DWS models:
10 kW, 30 kW, 60 kW and 100 kW.
This allows the equipment to cover small copper joints through larger industrial brazing applications.
3. How heavy is the handheld induction heating head?
The heating-head weight depends on system power.
The DWS-10 uses an approximately 1.5 kg head, while the larger DWS-30, DWS-60 and DWS-100 heads weigh approximately 3.1 kg, 4.5 kg and 8 kg respectively.
4. How long can the flexible induction cable be?
The current DWS series supports approximately 3–8 meters of cable, depending on the ordered configuration.
This allows the generator to remain several meters away while the handheld coil is positioned directly around the joint.
5. Can a handheld induction brazing machine braze copper tubing?
Yes. Copper tubing is one of the primary applications.
The page specifically identifies air-conditioner copper joints, copper cable connectors and transformer copper connectors as suitable applications.
6. Does the induction coil need to be customized?
Yes.
The current product page states that the induction heating coil is designed according to the customer’s requirements. Coil diameter, number of turns, shape and coupling distance should match the actual workpiece and brazing joint.
7. What cooling system is required?
The DWS series requires water cooling.
Cooling pressure should generally be at least approximately 0.3 MPa, while minimum flow ranges from more than 5 L/min for DWS-10 to approximately 30 L/min or more for the DWS-60 and DWS-100 systems.
8. What is the difference between a handheld and stationary induction brazing machine?
A stationary brazing system normally requires the workpiece to be positioned inside or next to a fixed induction coil.
A handheld system instead brings the heating head and coil to the component. This makes it particularly suitable for large assemblies, installed pipework, transformers, HVAC systems and other components that cannot easily be moved.
