Description
Harris HSLT604HD Heavy-Duty Auto-Ignite Trigger Torch
Harris HSLT604HD air-fuel trigger torch, part number 1400356, is a heavy-duty self-lighting hand torch designed for professional HVAC, refrigeration, plumbing, soldering, brazing, and heating applications that require greater heat output than a standard medium-duty torch. Rated at 12,900 BTU, the HSLT604HD combines fast piezo ignition, adjustable flame control, and a high-output swirl combustion tip for efficient heat transfer and dependable professional performance.
The HSLT604HD operates with either MAP-Pro™ or propane and is designed for standard 14.1 oz non-refillable fuel cylinders. Its ignition-button lock allows continuous operation, while the rugged aluminum cast body, ergonomic handle, and industrial-grade components are designed for repeated use in demanding field and shop environments.

Why Choose the HSLT604HD?
The Harris HSLT604HD is designed for technicians who need significantly more heating capacity than a standard hand torch while retaining the convenience of automatic ignition and a portable air-fuel system. Its 12,900 BTU output and swirl-flame design make it well suited for larger copper tubing and demanding professional soldering and brazing work.
Compared with the medium-duty HSLT604, the HSLT604HD provides more than twice the rated BTU output and greater soldering and brazing capacity, making it a strong choice for HVAC, refrigeration, plumbing, and mechanical contractors working with larger tubing sizes.

Frequently Asked Questions
What is the Harris HSLT604HD used for?
The HSLT604HD is a heavy-duty air-fuel hand torch designed for professional soldering, brazing, and heating applications including HVAC, refrigeration, plumbing, mechanical work, installation, and repair.
What is the heat output of the HSLT604HD?
Harris rates the HSLT604HD at 12,900 BTU, making it the highest-output model among the HSLT604HD, HTS99, HTM9, and HSLT604 hand torches shown in Harris's current brazing and soldering torch guide.
Can the HSLT604HD use both MAP-Pro and propane?
Yes. The Harris HSLT604HD is compatible with both MAP-Pro™ and propane. Soldering and brazing capacity varies according to the fuel being used.
How large of a tube can the HSLT604HD solder?
With MAP-Pro™, Harris lists soldering capacity from 3/4 in. through 4 in. tubing. With propane, Harris lists soldering capacity from 3/4 in. through 3 in. tubing.
How large of a tube can the HSLT604HD braze?
With MAP-Pro™, Harris lists brazing capacity from 1/4 in. through 1-1/4 in. tubing. With propane, Harris lists brazing capacity from 1/4 in. through 1 in. tubing.
Does the HSLT604HD have automatic ignition?
Yes. The HSLT604HD uses automatic start/stop ignition and includes a run-lock button for continuous operation.
What is the difference between the HSLT604HD and HSLT604?
The HSLT604HD is the heavy-duty 12,900 BTU version, while the HSLT604 is the medium-duty 6,100 BTU model. The HSLT604HD provides greater heating, soldering, and brazing capacity for larger tubing and more demanding work.
Does the HSLT604HD have adjustable flame control?
Yes. Harris identifies the HSLT604HD with adjustable flame control, allowing the operator to regulate torch output for different soldering, brazing, and heating applications.
What type of flame does the HSLT604HD produce?
The HSLT604HD uses a high-output swirl combustion tip designed to concentrate heat and improve heating efficiency during professional 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 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.
- Do not point the torch toward personnel or combustible materials.
- Never leave a lit or connected torch unattended.
- Review current Harris operating instructions and fuel-cylinder safety information before use.
