Internal welds-Frames, Stringers, Seams.

Started welding out last weekend.

Spent a whole weekend on just the the stringers with over 500 70mm welds done.

Starting from the centre I welded from left to right, front to back in a criss cross pattern trying not to 

put too much heat in any one particular place.

T&R settings. 138amps, 1.8 hz double pulse, -2 inductance.
Special trigger mode hot start enabled.
