I have a WIA 150 it's about 10 years old but still In good nick. I want to build an aluminium boat. I was wandering if this welder is capable of welding up to 6 mm aluminium and if so are there any accessories which will make welding easier such as wire feed rollers, Teflon liners etc.
The Weldmatic 150S is capable of welding up to 6mm thick steel plate, and so will be able to weld up to 6mm aluminium using 0.9mm wire on multi-pass welding. You will need to change over to the following to weld aluminium: W26-3/8 - 1.0/1.2mm aluminium rollers BE43115X – 1.2mm nylon liner BE7496 – 1.0mm contact tips(for 0.9mm wire) M535609S – Austmig 5356 0.9mm aluminium welding wire.
