Earthing point for welding

[daverclasper]

Hi, Say I wanted to do a bit of welding on a door, that's painted and still attached to car (maybe not a good earth to body through hinges), any tips on earthing the welder, apart from removing an area of paint from the door.  Also any earthing tips for other areas of car that are painted.

Thanks, Dave

How about the lock mechanism striker cover?

For doors undo any of the bolts - those holding the glass runners, for example - a few threads and earth to the bare unpainted metal now uncovered on the bolt shank.

Echo all of the above - Have the earth reasonably close to where you are welding.

Some experienced welders ditch the spring earth clamp  that comes with the welder and use an earth clamp  that is like sort  of G Clamp thing  to  get good earth connection.

As a completely self - taught (and still-learning) amateur welder I find the  Mig-welding.co.uk site run by Weld Quip continues to be a brilliant help to me.

It has  excellent  “How to do it “ advice on MIG ,TIG, with videos and also things like   paint spraying , air tools, compressor advice  various discussion forums

- and a very speedy mail order service for supplies.
