Fulcrum Brass Gas Welding Torch

Fulcrum Golden Brass Welding Torch Small

A welding torch, also known as a welding gun or welding handle, is a handheld tool used in various welding processes to deliver the necessary heat and materials to create and control the welding arc. It is a fundamental component in several welding techniques, including MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and some types of gas welding.

• Handle: The welding torch handle is the part the welder holds during the welding process. It is typically insulated to protect the welder from electrical shock and heat. The handle may also have ergonomic features to ensure a comfortable grip
• Trigger or Switch: Many welding torches have a motivation or switch on the handle that the welder can use to control the welding arc. Pressing the trigger initiates the gas and electrical current flow, creating the arch. Releasing the trigger extinguishes the arc
• Gas Flow Control: In processes like MIG and TIG welding, the torch may have a gas flow control valve on the handle. This valve allows the welder to adjust the shielding gas flow rate, which protects the weld pool from atmospheric contamination
• Nozzle: The nozzle, also known as the torch tip, is located at the front of the welding torch. It directs the flow of shielding gas and focuses the welding arc. The size and shape of the nozzle can affect the weld bead's characteristics
• Electrode Holder or Contact Tip: In MIG welding, the torch typically includes an electrode holder or contact tip that holds the consumable welding wire and makes electrical contact. This contact tip is replaceable and in direct contact with the welding wire, allowing for precise arc control
• Gas Hose: In processes that require shielding gas (such as MIG and TIG welding), a gas hose connects the welding torch to a gas cylinder or central gas supply. The gas flows through the hose and is directed to the nozzle when needed
• Power Cable: The cable connects the welding torch to the machine. It carries the electrical current from the device to the torch, allowing for the creation of the welding arc. The power cable is usually made of flexible, heat-resistant materials
• Cooling System (Optional): Water-cooled torches dissipate heat more effectively in some high-amperage applications, especially in TIG welding. These torches have a water circulation system that helps maintain a stable temperature
• Consumable Parts: Welding torches have various consumable parts that need regular inspection and replacement, including contact tips, nozzles, and electrodes (in MIG welding). Proper maintenance is essential for consistent weld quality
• Compatibility: Welding torches should be compatible with the welding machine and used process. Different techniques and devices may require specific types of torches and accessories
• Angle and Positioning: Welders can adjust the angle and positioning of the torch to control the heat input and weld bead characteristics. Proper torch manipulation is crucial for achieving quality welds
