And it arrived today! Still need to fit a plug as it came without one connected. UK import, so understandable and the shop provided one. All the other stuff was there, so when my son's at pre-school on Wednesday morning....
The welder is very nice. Haven't had too much arc time yet as it has been a very busy period at school (teaching is my day job), but I have been able to play with it and like it a lot!
@paulo1974: I don't weld alu, so no heat treatment for me.
