Why Choose the HSLT604?
The Harris HSLT604 combines the convenience of automatic ignition with the focused heating characteristics of a swirl-flame torch. Its 6,100 BTU output makes it a practical choice for technicians who need a compact medium-duty torch for routine soldering, brazing, HVAC, refrigeration, and plumbing work without the higher output of a heavy-duty torch.
Because the HSLT604 works with both MAP-Pro™ and propane, users can select the fuel that best matches the required heat output and application.

Frequently Asked Questions
What is the Harris HSLT604 used for?
The HSLT604 is designed for professional soldering, brazing, and heating work, including HVAC, refrigeration, plumbing, maintenance, and mechanical applications.
Can the HSLT604 use both MAP-Pro and propane?
Yes. Harris designed the HSLT604 for use with both MAP-Pro™ and propane. The available soldering and brazing capacity varies according to the fuel being used.
What is the heat output of the Harris HSLT604?
The Harris HSLT604 is rated at approximately 6,100 BTU and is classified as a medium-duty hand torch.
How large of a tube can the HSLT604 solder?
With MAP-Pro™, Harris lists a soldering capacity from 1/8 in. through 3 in. tubing. With propane, the listed soldering range is 1/8 in. through 2 in. tubing.
How large of a tube can the HSLT604 braze?
With MAP-Pro™, Harris lists brazing capacity from 1/16 in. through 1 in. tubing. With propane, the listed brazing range is 1/16 in. through 3/4 in. tubing.
Does the HSLT604 have automatic ignition?
Yes. The HSLT604 uses a built-in piezo igniter for self-lighting operation and includes an ignition-button lock for continuous use.
What is the difference between the HSLT604 and HSLT604HD?
The HSLT604 is Harris's medium-duty 6,100 BTU trigger torch. The HSLT604HD is the higher-output heavy-duty version intended for applications requiring greater heating capacity.
What type of flame does the HSLT604 produce?
The HSLT604 uses a swirl combustion tip designed to concentrate heat and provide efficient performance during soldering and brazing applications.
Important Operating & Safety Notes
- Use only with compatible fuel cylinders and connections specified by Harris.
- Confirm that the selected fuel provides sufficient heat for the intended soldering or brazing application.
- Soldering and brazing capacities vary between MAP-Pro™ and propane.
- Inspect the torch, connection, seals, and fuel cylinder before operation.
- Keep combustible materials away from the work area and maintain appropriate fire protection.
- Use appropriate eye, hand, and protective equipment when operating the torch.
- Never leave a lit or connected torch unattended.
- Review current Harris operating instructions and fuel-cylinder safety information before use.
