CorvAircraft> cracked headers, Tornado test

[AVLEC]

Mark if your Lincoln 175 squarewave is the same as the Miller 175
Squarewave, then it is a real Rolls Royce workhorse. I have a friend who
owns one and is airline rated to weld on 4130, stainless, titanium,
inkaloy(sp) and aluminim amongst others. He has been building aluminum boats
lately and literally keeps that welder working for twelve hours a day. He
uses a milk urn, which holds around 60 litres of water I assume, as a
reservoir for the torch cooling. He literally boils that entire urn of water
with the torch! It must be ten years old by now and hasn't given a days
trouble yet.
