Grounding welder

admin

Just outta curiosity should I ground my bobcat that is in the bed of my truck. It's bolted down to the bed but do I need to run a ground wire from the ground lug on the face of the machine to the bed of the truck? Only thing it says in the manual is to connected the auxillary ground to an earth ground if required by national or local code.93 Bobcat 225GMillerMatic 135HF Tig 91811
Reply:It is best for you and anyone else around your welder to take the ground lug, attach enough of 6 AWG stranded wire and a ground clamp to a good clean copper or steel rod that you can drive into the grounds at least 12". You don't have to do this, but I do and I feel safer and in control of my inviroment. Sent from my iPhone using Tapatalk
Reply:Most generators don't require an earth driven ground.  It's unnecessary and pointless unless your generator is a "separately derived system." http://www.imsasafety.org/journal/ma03/ma5.htmLincoln Power Mig 216Lincoln AC/DC-225/125Miller  625 X-Treme PlasmaMiller 211 Forney 95FI-A 301HF 91110Victor Journeyman O/PMilwaukee DaytonMakita  Baileigh NRA Life Member
Reply:On the stated website, in both drawings on the same page showing two different systems there is a ground on each secondary of the transformer and generator. I still say it is just such a simple and easy task to go ahead and install your ground rod. If the "load" shorts to ground and you have that load laying on the bed if your truck and you touch the load or the bed you can be zapped. You being the path of least resistance. And since a ground isn't necessary tear of the ground lugs on all of the power cords and equipment. It may not be necessary, except the one time it is. I don't want to go to that wife and child and say dad isn't coming home anymore over something so simple as a ground. Sent from my iPhone using Tapatalk
