What Are HOT Devil Torches?

HOT Devil Torches are portable gas-powered tools that direct a concentrated flame onto a fitting, joint, fastener or workpiece.

Unlike a gas lighter designed primarily for ignition, a blow torch maintains heat for suitable soldering, brazing & heating processes.

Within the HOT Devil Trade Map range, burner design changes how that heat reaches the work. A swirl flame is designed for rapid heat transfer while different burner tubes can alter the size, position & concentration of the working flame.

Key Trade Map options include:

The useful difference isn't simply maximum temperature. Burner shape, flame pattern & the amount of heat required by the workpiece should all influence the choice.

Why Choose HOT Devil Torches?

A small copper joint doesn't necessarily need the same flame characteristics as a larger piece of metal requiring substantial heat input.

HOT Devil provides several torch configurations so the flame can be better matched to the work.

► HD027 Swirl Flame Torch – stainless steel burner tube with rapid swirl-flame heat transfer
► HD030 Trade Map Torch – brass adjustable burner tube with swirl-flame action
► HD032 Twin Torch Kit – interchangeable turbo & precision pencil-flame burner tubes
► HD600 Super Flame Torch – larger burner assembly for demanding heating work
► Up to 2050°C across these Trade Map models
► Auto ignition for convenient flame starting
► Anti-flare features across the Trade Map models
► CGA600/BOM Trade Map gas compatibility
► Adjustable gas flow on applicable models

The HD032 is particularly useful when the type of work changes. Its turbo burner provides one approach to faster heating while the pencil-flame burner allows heat to be concentrated more precisely.

The HD600 moves in the opposite direction with a larger burner assembly for jobs where greater heat delivery across the workpiece is the priority.

Common Applications

Copper Pipe Soldering

The goal isn't to make the fitting as hot as possible. It's to bring the prepared joint to the appropriate working temperature.

HOT Devil Trade Map torches are suited to silver soldering with the HD032 also providing a pencil-flame option for more delicate heating work.

Before lighting the torch, clean & prepare the pipe, fitting & joint appropriately. Poor preparation isn't corrected by simply applying more flame.

Brazing

Brazing often demands substantial heat across the joint area.

HOT Devil Trade Map torches can be used for suitable brazing applications involving copper, mild steel & aluminium.

Workpiece size matters. A larger section of metal can draw heat away from the joint considerably faster than a smaller component which makes flame pattern & heat transfer important considerations.

Heat Shrink

A torch can provide fast localised heating where direct flame is appropriate for the particular heat-shrink material & surrounding installation.

Keep the heat moving where required rather than concentrating the flame unnecessarily in one spot.

Heating Seized Fasteners

A rusted nut can resist another metre of leverage while controlled heat approaches the problem differently.

HOT Devil Trade Map torches are suited to heating rusted nuts, bolts & screws where direct flame can be used safely.

Before ignition, check what surrounds the fastener. Wiring, fuel, oil, seals, hoses, plastic components, paint & bearings can all influence whether flame heating is appropriate.

Thawing Suitable Frozen Pipes & Locks

Selected torch models can also be used for thawing suitable frozen pipes & locks.

First identify the material being heated & inspect the surrounding area. Direct flame isn't appropriate for every pipe, coating, fitting or nearby component.

Fabrication & General Heating

Workshop jobs don't always fit neatly into soldering or brazing.

A torch may also be useful when controlled localised heat is required during suitable fabrication, repair or maintenance work.

Product Selection Guide

Start With The Material & Job

What needs to get hot & why?

Establish whether you're:

► Silver soldering
► Soft soldering
► Brazing
► Applying heat shrink
► Heating a seized component
► Thawing a suitable pipe or lock
► Carrying out general heating work

Then consider the size & material of the workpiece.

Choose The Flame Around The Work

A temperature rating tells you what the flame can reach. It doesn't tell you how that heat is distributed.

Swirl flames are designed to move heat rapidly around the work area.

A pencil flame provides a more concentrated heating point.

The HD032 gives you both turbo & pencil-flame burner options which can be useful when one kit needs to cover different heating tasks.

Compare The Main Trade Map Models

HD027 – Trade Map Swirl Flame Torch Kit

A strong starting point for trade heating with a stainless steel burner tube, swirl flame, auto ignition, anti-flare operation & adjustable gas flow.

It suits applications including silver soldering, brazing, heat shrink & general heating.

HD030 – Trade Map Torch Kit

The HD030 changes to a brass adjustable burner tube while retaining swirl-flame heat transfer.

Its burner tube can be repositioned to make the torch easier to approach from different working angles.

HD032 – Trade Map Twin Torch Kit

One heating job may need speed while the next needs precision.

The HD032 includes interchangeable turbo & pencil-flame burner tubes, making it the standout option when different flame profiles are useful across the workday.

HD600 – Trade Map Super Flame Torch Kit

The HD600 uses a large stainless steel & brass burner assembly with a powerful swirl flame.

Consider it where substantial heat delivery is more important than working with a smaller burner configuration.

Confirm The Gas Connection

The Trade Map torches covered here use CGA600/BOM-compatible Trade Map gas cylinders.

Don't assume another gas cylinder is suitable simply because it appears physically similar. Check the specific torch & fuel requirements before connection.

Check What Comes In The Kit

Torch head, burner & gas cylinder can vary between products.

Before ordering, check the individual product listing so you know exactly what is supplied with the selected HOT Devil torch kit.

This is particularly important when replacing an existing torch or buying additional equipment for a workshop already holding compatible cylinders.

Consider How You'll Reach The Work?

Installed pipework & machinery rarely sit at an ideal bench-top angle.

Adjustable burner tubes & anti-flare features can make a meaningful difference when the work is overhead, underneath equipment or positioned close to surrounding components.

Always operate the specific model according to its instructions.

Check The Area Before Ignition

A torch affects more than the surface directly in front of the flame.

Before heating, look for:

► Fuel & flammable liquids
► Gas lines
► Electrical wiring
► Rubber hoses & seals
► Plastic components
► Insulation
► Paint & coatings
► Combustible building materials
► Concealed materials behind the workpiece

Where the surroundings can't be made suitable for direct flame, use another heating method appropriate to the work.

Expert Tips

Prepare The Joint Before Reaching For More Heat

More flame won't compensate for poor preparation.

When soldering or brazing, inspect the surfaces, joint fit & applicable filler requirements before heating begins.

Watch How The Workpiece Absorbs Heat?

Two components exposed to the same torch can respond differently.

Material type, thickness & overall mass affect how quickly heat moves away from the flame. Adjust the heating approach to the work rather than relying on one technique for every job.

Use The Burner That Matches The Area

A broad swirl flame can rapidly transfer heat around a larger section while a pencil flame concentrates the working area.

If the job requires both approaches, a multi-burner configuration such as the HD032 can reduce the need to compromise between them.

Check Behind The Joint

Pipework can hide timber, insulation, wiring & other materials behind the visible surface.

Inspect the area beyond the fitting before lighting the torch rather than focusing only on what's directly in front of you.

Don't Heat A Seized Bolt Without Checking What's Attached?

A stubborn fastener may sit next to a seal, bearing, fuel component, painted panel or electrical connection.

Identify what could receive transferred heat before deciding whether direct flame is appropriate.

Inspect The Torch Before Connecting A Cylinder

Check the burner, controls, gas connection & accessible components for visible damage.

Use the specified cylinder connection & follow the operating instructions supplied with the torch.
