Yup it's pouring with rain and there's an emergency welding job which
has to be done...
Does it help to have a return lead with two clamps
- one attached securely to the structure (in this case the barge you
are on) before you turn on the generator / welding-machine
- the other the clamp you attach to the workpiece
The reason would be to avoid being electrocuted all the time as you
try to move the return / "earth" clamp.
Surely if there is a permanent attachment of the return clamp to the
barge, the "moveable" return-clamp would always be at the potential of
the barge and you couldn't get shocked when you transfer your working
So that both the "new" piece of metal and the "existing structure" are
both tied to "ground" potential and you don't have to be careful about
which side you strike-up on in avoiding getting shocked. Because the
"free" / "floating" return clamp can be put on the "new" part.
Have I got this right?
Would you make-up a short length of cable between male and female
"bayonet" connectors, with a juntion in the short length branching-off
to the clamp you attach to the main structure for the duration the
generator is on?
Thinking is - you could split any pair of bayonet connectors in your
welding cable run where there is a good place to attach to the barge /
structure, and insert this fitment and get that good enduring earthing
Thanks in advance,
