I was reading a post of a few days back.

A point made about cleaning the end off the electrode to allow it to start caught my eye.

Working in an industrial situation people do not file ends off their electrodes to get them started.It is simply not time efficient.

Instead what occurs is a regular and ongoing maintenance of their equipment and the ancillaries.Once an earth clamp unit is noticed giving problens it is simply replaced. On a lesser budget you and I can't afford that, so a strip down of said clamp is usually necessary. If your clamp or any part of the earth cable /connections becomes hot it is a dead giveaway that there is a resistance present.

A squirt of WD 40 won't usually do, so a check of the cable to ferrule crimp and the integrity of the bolted and screwed connectors and their associated washers is in order. A buff off of any built up crud / corrosion will restore your electrical conductivity back to what it should be.

Although it is an infomercial there is to be some very good information re earth clamps to be gleaned from the following: https://www.weldclass.com.au/blog/9-...th-a-bad-clamp.

It will probably amaze some, how much conductivity is lost through a poor connection.
