My Cebora Tigstar 180 has the machine casing connected directly to the earth pin of a 13amp mains plug.
I have been asked to do some work with my welder in a steel container on a steel bench welded to the container walls. The mains power supply in the container uses metal-clad sockets screwed to the container walls with the mains earth therefore connected to the walls. If I connect my welders work earth clamp to the bench I am effectively short circuiting one side of my welding circuit direct to the case of my welder.
I have always been told it is not advisable to rest work against the metal casing of a welder for fear of short circuit. Am I worrying unnecessary about this short circuit or should this situation be avoided for fear of damaging the complex electronic circuitry in a modern hi-tech welding machine?
Some guidance and advice on this issue from the learned members who understand welder circuitry would be most welcome, thanks Pete.
