Soldering Torch & Fuel Selection Guide

At Bromic we have the widest range of trade focussed soldering & brazing products, and we know that selecting the best hand torch and fuel source for your project is important. You need to ensure you can work effectively and efficiently to complete your soldering, brazing or welding project. There are a variety of torches, torch kits and fuel options available and in this article, we will provide a comprehensive guide to selecting the correct fuel type and torch flame type for the job.

When considering the best heat torch and fuel for any trade project it is important to note the following:

  1. Various metals melt at varying temperatures as per graph below
  2. Bromic Fuel types allow flames to achieve various temperatures based on fuel composition.
  3. Ambient (environmental) temperatures may affect the flame temperature
  4. Ensure you select the appropriate Bromic Fuel type for melting the metal used in your application

Below is a graph which displays the various metal melting temperatures.

Selecting the Right Fuel for Your Job

When selecting your Fuel, it is good to understand the different applications for each fuel source.

  • Butane: Well-suited for soldering electronic circuits, heat shrinking, cooking and jewellery design and repair.
  • Propane: Ideal for smaller soft soldering jobs, removing paint, caulk or putty and loosening rusted nuts and bolts.
  • MAP//Pro™: Designed for larger, hotter jobs such as soldering large diameter copper pipe, brazing, or heat-treating. This fuel is ideal for plumbing, soldering & brazing as well as automotive repair and is ideal for professional tradespeople such as HVAC techs and plumbers.
  • Oxygen & MAP//Pro™: When oxygen is combined with Map-Pro, this combination of fuel sources are hot enough for brazing, light welding, hardening steel, and thin metal cutting and is ideal for professional tradespeople such as HVAC techs and plumbers.
  • Electric: These soldering irons are great for light to heavy soldering, DIY jobs and electrical repair. Please move electric to the first point so the list goes up in ‘professional grading’.

Selecting the Best Flame Type for your Torch

The flame type is the size, shape and type of flame that the hand torch produces. Different flame types are suited to different applications. The type of flames we cover include:

  • Micro Flame
  • Pencil Flame
  • Webbed Flame
  • Jumbo / Jet Flame
  • Swirl Flame
  • Ultra Swirl Flame
  • MAP/Oxy Flame

Hand Torch Flame Types

When selecting the flame type of your hand torch, we recommend the following:

STEP 1. Select your application
STEP 2. Match application to corresponding fuel
STEP 3. Choose a flame type

In the table below we outline each of the fuel types and the recommended flame type for each application.

  • Jewellery design: heating the metal allows for easier shaping of the jewellery piece
  • Repairing jewellery: joining broken jewellery pieces together using the heat from the torch
  • Soldering silver
  • Soldering copper pipes: using the heat to connect two pieces of copper and make the joint watertight
  • Thawing frozen pipes and locks: by heating it until the mechanism works correctly
  • Loosening rusted nuts and bolts: heat it with a torch before cranking it with a wrench
  • Removing paint or paint stripping: use instead of a heat gun to warm up the paint to make it easier to remove
  • Removing caulk: soften the caulking with the heat to make it easier to remove
  • Removing putty: use the heat to soften the putty for easy removal
  • Lighting grills and fire pits: use the steady flame to get the fire started easier
  • Brazing copper pipes and steel: joining the metals together using heat at the joint
  • Hardening steel: using high temperature from the hand torch
  • Repairing garden tools: repairing broken metal joints
