Shouldnt be too long now Mal, hopefully in the next 4 weeks or so.
All the welding is either using a mig or spotwelder. One of the Migs is an inverter, it doesnt get the whole area as hot so it is pretty good controlling distortion. We have an inverter spot welder as well, but it is more for new cars with HS steel. The normal spot welder is fine on the old girls. When we replace panels we spot weld them as per factory to keep it looking as original as possible.
