Im building an aluminium (7 and 8 mm plates ) double ender sailboat. 40 feet long, The boat is built upside down.
First i was thinking tig welding this together, but since i built in 20 cm wide lapstrakes it will be a lot of welding, so probably i will switch to MIG to weld the laps (welding laps on both side it means at least 1000 meter of welding, so its some hours welding job to do)
for tig im using a lincoln squarewave 255. for mig i have a smaller lincoln powertec 250 but probably need something bigger and better. (hopefully with wirefeeder)
