Description and types of parts:
Responsible for properly directing the shielding gas to the welding pool, protecting it from the surrounding atmosphere. Depending on the application, nozzles can be made from various materials, and some, e.g., for welding aluminum, may be coated to prevent spatter from sticking.
This is the component that conducts current to the welding wire, and its size and type must match the diameter of the wire and the current carrying capacity of the torch. It is usually made of high-quality copper or brass.
Connects the current cable of the torch to the current tip and the burner, ensuring the flow of current.
The body of the handle, which contains the other components of the torch. In liquid-cooled torches, the handle heats up less, increasing work comfort.
- Insulating sleeve (centering insulating cap):
Isolates the components of the torch, preventing short circuits and maintains the optimal positioning of the nozzle.
Ensures proper guiding of the wire inside the torch, selected depending on the type of wire (steel for steel wires, Teflon for aluminum or flux-cored wires).
Types of torches based on cooling:
Mainly used with smaller welders, lighter and cheaper, ideal for situations where the MIG welder needs to be easy to transport.
Used in industry, for multi-shift work and at high current levels (above 400 A). They are more durable, comfortable to use (the handle does not heat up), and consume fewer consumable parts.
