Inverter tigs are the way forward, all the features (and more) of a 1/4 tonne machine but at just a few KGs. They substitute heavy internal components like transformers for electronic components.
Single phase inverters are available up to about 200 amps so plenty enough power for most users. They'll usually run off a 13a supply too!
'Weldequip' on here is a welding and cutting supplies dealer who also sells those weldstar ones, Simon718 bought one from him a while back. Might be worth sending weldequip a PM and seeing what he can do for you.
Could someone please enlighten us to the process named in the advert as "WIG Welding",,,, hair extensions,,,,,, possibly anyone..........
WIG stands for Wolfram Inert Gas.
