We have different types of Torch Systems:

• Promatic System

• Pro 88 System

• Pro 86 System

• Soldering Iron Systems

  Our systems are designed to be as flexible as possible, meaning that you can choose a handle of your choice and combine it with different neck tubes and burners depending on your needs.  

  Our Product Finder can help you determine which torches are recommended for different applications. Once you view a certain product series, you will be able to see all the different combinations of neck tubes and burners that belong to that system.  

  Torch systems should always be combined with a Sievert Propane Hose and a Sievert Pressure Regulation Device to achieve maximum performance and safety. 

These systems are hand-held and mobile, meaning that you do not need to use a Sievert Propane Hose or Sievert Pressure Regulation Device to operate them. They are operated through our disposable / refillable gas cartridges / cylidners.

What is a Soldering Iron System? 

A Soldering Iron System is used for sheet metal . These torches combine with copper bits. Just like our Torch Systems, the Soldering Irons should always be combined with a Sievert Propane Hose and a Sievert Pressure Regulation Device

Bar pressure is crucial in propane torch systems as it directly affects the performance and safety of the torch. In these systems, the pressure regulator is responsible for maintaining a consistent pressure level, ensuring that the propane gas flows steadily from the cylinder to the torch. Sievert burners are designed to be operated on a recommended bar pressure to ensure performance and safety.  

Gas consumption is the amount of gas that is spent when using a certain Sievert burner. It’s measured in grams per hour according to the recommended bar pressure of the burner. When you know the gas consumption, you can technically calculate how long a gas cartridge / cylinder will last.  

Combustion in a blowtorch is a controlled chemical reaction where fuel, typically propane or butane, mixed with oxygen is ignited to produce a high-temperature flame. 

A quick connection between a torch handle and a propane hose allows for fast and secure attachment or detachment without requiring tools. These connectors enhance safety, efficiency, and ease of use.

The male end snaps into the female end (hose side), locking in place automatically. A release sleeve allows for disconnection.

A flare-up occurs when gas in a liquid state flow through the jet orifice of a lit burner causing a large flame that can be a hazard. .
To avoid this, make sure to use Ultragas, Propane gas or MAPP gas with our blowtorches.  

The Handyjet is designed with a pre-heating tube inside the burner meaning that even Powergas can work without any flare-ups.  

In general, when you ignite a torch, let it run between 20-30 seconds in its upright position before starting to use it in different angles / upside down. 

Gas might still be in the propane hose when you are done using the torch system. If you are storing your equipment in cold weather, the gas might change state to liquid form so the next time you ignite your torch system you might experience flare-ups. To avoid this happening, when you are done using the torch make sure the gas that is still in the propane hose is released in a safe manner.

Make sure you point your torch in a direction where there is no risk for damage and away from any heat sources. 

Turn off the gas flow on both the handle and the cylinder. 

Gently turn on the gas flow on the handle and let the trapped propane gas to escape. 

Intechangeable burners are burners that use a special connection (such as M20 x 1 or M8 x 0,75) that you can screw on a neck tube.  

The Twist ‘N’ Lock technology burners however don’t use a special connection, you just twist and lock them into place. You do not need to screw them on and allows for fast and secure exchange of burners without hassle. This feature is unique to Promatic and Powerjet.

These will help you identify which type of gas cartridge / cylinder a certain blowtorch is compatible with.  

1. M14 x 1.5 (Metric Thread) 

• Standard: ISO Metric Thread (ISO 965-1) 

• Thread Diameter: 14 mm 

• Type: Metric, straight (not tapered) 

2. UNEF 1" (Unified Extra Fine Thread) 

• Standard: Unified Thread Standard (UNEF – Unified National Extra Fine) 

• Thread Diameter: 1 inch (25.4 mm) 

• Type: Inch-based, fine thread, straight (not tapered) 

3. EU 7/16" (European Gas Thread Standard) 

• Standard: Typically refers to a 7/16-inch in gas fittings. 

• Thread Diameter: 7/16 inch (≈11.1 mm) 

This will help you identify the connection between a torch system handle and the propane hose.

1. M14 x 1 (Metric Thread)

• Standard: ISO Metric Thread
• Thread Diameter: 14 mm
• Pitch: 1.0 mm (distance between thread peaks)
• Thread Type: Straight (parallel)

2. UNEF 9/16” LH (Unified Extra Fine, Left-Hand Thread)

• Standard: Unified National Extra Fine (UNEF)
• Thread Diameter: 9/16 inch (≈14.3 mm)
• Pitch: 18 threads per inch (TPI)
• Thread Type: Left-Hand (LH) – meaning it tightens counterclockwise instead of clockwise

3. BSP 3/8” LH (British Standard Pipe, Left-Hand Thread)

• Standard: British Standard Pipe (BSP)
• Thread Diameter: 3/8 inch (≈16.7 mm outer diameter for BSPT)
• Pitch: Typically 19 TPI for BSPP (parallel) or BSPT (tapered)
• Thread Type: Left-Hand (LH) – counterclockwise tightening

This will help you determine which neck tube fits with our torch system handles. 

• "G" → Denotes BSPP (British Standard Pipe Parallel), meaning the threads are parallel (non-tapered). 

• "3/8"" → Refers to the nominal bore size of the pipe, not the exact external diameter. 

• The outer diameter (OD) of a G 3/8" thread is ≈16.66 mm (0.656"). 

• "19" → Represents the thread pitch as 19 threads per inch (TPI). 

• Thread Standard: ISO 228-1 (for BSPP) 

• Sealing Method: Since BSPP threads are parallel, they do not seal by thread engagement like tapered threads (BSPT). Instead, they require a sealing washer, O-ring, or bonded seal for a leak-free connection. 

This helps you identify which burners within our systems fit to a specific neck tube.  

1. M20 x 1 (Metric Thread) 

• "M" → Denotes ISO Metric Thread. 

• "20" → Nominal outer diameter of the thread is 20 mm. 

• "1" → Pitch is 1.0 mm (distance between thread peaks). 

• Thread Type: Parallel (not tapered). 

2. M8 x 0.75 (Metric Thread) 

• "M" → Denotes ISO Metric Thread. 

• "8" → Nominal outer diameter of the thread is 8 mm. 

• "0.75" → Pitch is 0.75 mm (fine thread). 

• Thread Type: Parallel (not tapered).
