We see from your search that you're looking for information on the term "Welding Current",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release Standard MIG/MAG welders are heavy duty from
Wilkinson Star, which we summarised at the time by saying "Three-phase 400V 25/32A standard welding machines are designed for heavy duty MIG/MAG welding applications including general fabrication and structural steel work using solid or flux cored
wires".
A couple of weeks before,
we featured the news release Weld and fastening monitor works at machine from
Kistler Instruments: "A battery powered measuring system for analysing joining methods, such as spot welding, clinching and riveting, measures and records the force-vs-time and force-vs-distance curve".
In August 2007, we covered the news from WeldComputer Corporation
concerning its Welding inverters - mash seam welding
- take a look at Inverters are for mash seam welding
which says: "Welding inverters rated at up to 800A for mash seam welding operate in current, voltage and power feedback modes and monitor key welding parameters".
Take a look also at the news release from ESAB, Compact TIG torches weld in tight spaces,
as well as Arc welding machine reduces spatter, saves costs from Lincoln Electric Company, The,
and Petrol driven welding and generating sets from Wilkinson Star.
