2. Miller Electric - Wikipedia

   en.wikipedia.org/wiki/Miller_Electric

   In 1929, [2] Niels Miller designed a small arc welder for "stick welding" that could operate on the electrical supplies in rural Wisconsin that was lighter and less expensive than the DC rotary units previously available. The first machine was built from recycled scrap steel and coil windings in his basement.

3. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

   en.wikipedia.org/wiki/Xcel-Arc

   The Xcel-Arc Welding NZ was founded in 1994 in New Zealand. [2] It provides plasma cutters, TIG-welding, MIG, [3] Arc welding machines, machine trolleys, [4] and protective gear. [5] [6] Xcel-Arc manufactures machines that comply Australian-New Zealand market standards AS/NZS60974-1 and EN 50199.

   Plasma Arc Welding: 15: PAW Nonconsumable electrode, constricted arc Tubing, instrumentation Shielded Metal Arc Welding [5] 111: SMAW Consumable electrode covered in flux, can weld any metal as long as they have the right electrode Construction, outdoors, maintenance Submerged Arc Welding: 121: SAW Automatic, arc submerged in granular flux

6. Plasma arc welding - Wikipedia

   en.wikipedia.org/wiki/Plasma_arc_welding

   Plasma arc welding is an arc welding process wherein coalescence is produced by the heat obtained from a constricted arc setup between a tungsten/alloy tungsten electrode and the water-cooled (constricting) nozzle (non-transferred arc) or between a tungsten/alloy tungsten electrode and the job (transferred arc). The process employs two inert ...

7. Hyperbaric welding - Wikipedia

   en.wikipedia.org/wiki/Hyperbaric_welding

   Dry hyperbaric welding involves the weld being performed at raised pressure in a chamber filled with a gas mixture sealed around the structure being welded.. Most arc welding processes such as shielded metal arc welding (SMAW), flux-cored arc welding (FCAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), plasma arc welding (PAW) could be operated at hyperbaric pressures, but ...
