ECN Forum Forums General Topics of the Trade General Discussion Area Imaginary scenario: How do you temporarily hook up an electric welder?

OK, picture this:

You are a window gate manufacturer hired to put bars on the windows of a storefront.

You've finished welding together the gate at your shop and have arrived at the jobsite to mount the gates.

First your helper drills eight holes around the perimeter of the window opening in the poured-concrete walls and drives short pieces of metal bar as anchors (how Latin American is this? ).

Both of you will finally weld the entire gate to these stumps of bar using a portable electric welder.

Question is....how and where do you hook up your electric welder?

The store owner will not allow you to clip the welder's jumper-clamps to his brand-new panel's bus bars (for obvious reasons)....

What do you do?
