Hey Steve…
thanks for the link…but this is where the confusion is for people…
It does talk about attaching the ground to the water pan…but the ground from a plasma cutter is not the material clamp…there actually is on many plasma units and bonded ground on the back of the case to ground to the table…this is what the line refers to
the material clamp is not a “ground”…read this thread…
it can be mistaken by many…and many have made the same mistake
what is not great is the fact that the pictures show a plasma torch being used on the tables…but it does not show the material clamp on the metal being cut…which adds to the confusion of the whole thing…
but always remember there is a material clamp from a plasma unit…not a “ground” clamp…
I will try to flag this up the line for possible changes to some of the wording Langmuir uses in the instructions…
