The Goncz action cycles as a closed-bolt mechanism. The user operates the bolt with a knob on the upper-left side of the gun similar to a Tec-9. When Claridge Hi-Tec began production they modified the Goncz design by adding a bolt hold-open button on the left side of the frame. None of the guns produced by Goncz Arms had this feature.
TIP TIG is a subset of gas tungsten arc welding (GTAW), using a mechanism called filler wire agitation to enhance molten weld pool dynamics. This agitation has been found to enhance the weld puddle fluidity and release evolving gases, reducing the chances of inclusions and porosity, and also separate impurities.
GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.
The company also offers welding gun, wire feed mechanism, power source, cooling unit, and TIG welding torch maintenance services. Its products are used in metal fabrication workshops; automotive industry; construction; chemical, process, and oil and gas industries; shipbuilding and offshore; welding automation; and other applications.

Shielding gases fall into two categories—inert or semi-inert. Only two of the noble gases, helium and argon, are cost effective enough to be used in welding.These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals.
Gas tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a non-consumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material. [43]
Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
The Panzerhaubitze 2000 (German pronunciation: [ˈpant͡sɐhaʊ̯ˌbɪt͡sə t͡svaɪ̯ˈtaʊ̯zn̩t]), meaning "armoured howitzer 2000" [3] and abbreviated PzH 2000, is a German 155 mm self-propelled howitzer developed by KNDS Deutschland (formerly Krauss-Maffei Wegmann (KMW)) and Rheinmetall in the 1980s and 1990s for the German Army.
