Tig Shock

[geeman]

Well i have a hf start dc tig and i was trying to weld somthing, but forgot to connect the earth lead. When i pressed the trigger, there was the little hf sprks that try to get the arc started even though the earth lead wasnt connected, however, i felt a big tingle in my left hand where i was holding the filler rod and it made me drop the filler rod. It seems that i was earthing the workpiece, which is kind of scary as it seems dangerous. It felt quite painful and like a bad electric shock. I was wearing gloves as well as id never wled without gloves.

Is this somthing common as it really seems scary, but at least it didnt do me any significant harm.

 

[^neo^]

Yep, very common if you dont put the earth on!

I suspect the same would apply to a Plasma cutter too.

the left arm jingle
as has been said quite common if you have a bad earth

Quite common that....

I once was holding onto some big parts while someone went to tack it up on the floor, we had forgotton to put the earth on the work, from the bench.... i was resting my backside on the bench

Some guys in youtube shock themselves with HF for fun..

Was fitting a new tungsten one day, accidentally pressed the trigger...HELLO.... that was a wake up call I don't want to repeat too often.

The amount of times I have put a bit of cardboard between the item I am tig welding and the bench to avoid scratches and then not moved the return lead is beyond counting!
I even managed to give myself a jolt right where you really want one whilst leaning forward to weld a part just within reach :-(

When I was teaching welding, one of the apprentices decided to pull the tungsten out of the torch with his teeth! Needless to say, he managed to depress the button whilst doing so! He never did it again!!! lol.

hf alone shouldnt hurt... i often find meself bored doing that.. just make sure your not earthed!!

I know of someone who did that very recently, who was it now..........

Good to hear I'm not the only daftie out there. I'm still learning my TIGgin', and once I touched my filler into the tungsten... whilst welding... I strongly try not to after that.

You need to be a lot more careful with Plasma cutters - quite high open circuit dc voltage/current, as opposed to just HF start. W/A

Tig welding last week when the bead turned into cr*p. Lifted the torch and slightley pressed the pedal to listen for the hiss of argon, You've guessed guys, mighty SHOCK to the right ear lobe, Certainley gave me a wake-up call. Won't be doing that again soon,and right first time, yes the gas had run out, Next shock was to the wallet with a trip to B.O.C. for a refill.

Cheers Gordon.

nothing like a shock to wake you up i have had a few and cracked a few ceramics in the process when the torched gets dropped
