sveisepistol

A sveisepistol, also known as a welding gun or welding torch, is a tool used in welding to deliver welding consumable and shielding gas to the weld pool. It is connected to the welding machine via a power cable and a gas hose. The operator holds the sveisepistol and guides it along the joint to be welded.

There are different types of sveisepistols depending on the welding process. For MIG/MAG welding (Metal Inert Gas/Metal Active Gas), the sveisepistol feeds a continuous wire electrode and delivers shielding gas. For TIG welding (Tungsten Inert Gas), the sveisepistol holds a non-consumable tungsten electrode and the filler material is fed separately, often by hand, while shielding gas is also supplied. Plasma welding also uses a specialized sveisepistol that creates a plasma arc.

The design of a sveisepistol typically includes a trigger to initiate the welding process, a nozzle to direct the shielding gas, and a contact tip (in MIG/MAG) or collet (in TIG) that transfers the welding current to the electrode. Many sveisepistols also feature a swan neck or gooseneck design that allows for better access to awkward welding positions. Regular maintenance, such as cleaning and replacing worn contact tips or nozzles, is crucial for ensuring optimal performance and weld quality. The choice of sveisepistol depends on the specific welding application, the materials being joined, and the welding current required.
