Do yourself a favour...

...and buy yourself a set of these.

If you don't already have a set, you can get one from RS components. The two VDE spanners and the 12 mm socket were extra to the kit, but the whole lot came to about $1000.

It's a sh*tload of money, but in my circumstances it's a matter of life and life without eyesight (and possibly a defibrillated heart).

The red plastic stuff is considerably more resilient than PVC tape!

It's plastic dip

hard as nails

Even the cans of the stuff to dip your own tools are expensive

I just heatshrunk any tools that I was using.

Same. I have a set of insulated screwdrivers from Jaycar, and I just use the double-wall glue-lined heatshrink on everything else.

Yeah, I figured 700 V was enough to warrant something a bit better engineered. Not that the pack will ever be at 700 V while I'm working on it, but handy nonetheless.

good call

Pfffft just man up :p
Must be an AC owner thing...
DC owners cld totally take a 700volt hit and shake it off

Oh I could do it.

I could only do it once though

Yeah I copped a 200amp sap from not earthing the tig and holding the metal

Got to say for 5 to 10 seconds I think I may have been strong as the hulk.
But 3 min later it was that feeling you get when winded but plus lactic acid

If 200 amps flowed through your body, you'd be turned into a fireball in less than a second.

After skin resistance is overcome, the human body has around a kilo-ohm of resistance (from poor memory, and I'm too lazy to look it up). Power equals I^R, so that's around 200^2 x 1000 = 40 megawatts.

The 200 amps only flows through a very low resistance circuit, like the welding wire and air heated to a plasma state.

[ Edit: and with E = I.R, it would take around 200 x 1000 = 200 kV to force 200 A through a human body. ]

50mA for 30ms kills you, or is it 30mA for 50ms?

only if it crosses the hart

Yup but the HF of the tig is just a fun pulse
