Welding on tractor

[jake98]

Any truth to the rumor that it can fry the electronics?

yes..

Yes and No! It really depends on the location of the welders ground and electrode. If you can keep them close to the work area you should be all right. It is also safer to disconnect both battery cables from the battery. There are a couple of companies that make an anti zap device that protect the electronics from getting a surge when welding. I have one that MAC Tools sold and it is simple to use.

I spoke with mechanic at my Bobcat dealer. Asked him if he disconnects the battery before welding. (This guy welds a lot). He said never has, never had a known problem. I have welded many things attached to skid steers and tractors and not had an issue. My local welding guy also does a lot or welding on trucks putting in goose neck hitches and does not disconnect the battery. I have come to the conclusion, that my chance of screwing up the battery or terminals is probably greater than a electrical issue caused by welding.

Do disconnect the batt ground before welding on a tractor or veh.
Better to be safe than sorry.
electr do fry in situations.

I have worked for the D.O.T. for 21 years back when I was a truck driver I was the guy that did all the welding in our Crew when the Cert.Welder was off .We always disconnected the batteries when welding or at the least hit the disconnect switch.These trucks have such high tec computers in the cab to control the sanders that it was a precaution we always took.Was there really a good reason ? not sure in our case it was a matter of not voiding the warrenty on the electronics I think. None of us ever wanted to be the guy that fried $ 30,000.00 of electronics. Probaobly no need but someone some where had a reason for it I am sure.

Back in the 70s I worked for a local building supply company. During the Winter months we often had to use jumper cables to get the Mack diesels started. I witnessed what can happen when someone cross connects the batteries. The explosion almost knocked me off my feet and I was a good 20 yards away when they went.

This may not apply in any way to what the OP asked, and you can call me superstitious, but I always disconnect the battery and remove it a good distance from the vehicle if I can't remove the thing to be welded from the vehicle itself. Electricity & hydrogen gas never seem to play nice together.

scary stuff aint it

Well, just for the record, the tractor still works.
TSC had these box hitch reducers for under 10 bucks. I used 7018 rod and man, the stuff melts like butter. Had been using 6011 and I'm not sure if that's the whole difference, as I may have not had enough juice last time, but what a pleasure when it works right. :thumbsup:

The theory is, a welder is creating a controlled short, routing a flow of electricity through the steel your working on, which is why you want the ground clamp as close to the work area as possible. Its a fairly closed loop. Now if you go attaching it to your 3pt hitch and try to weld your bucket (gross example) you may very well fry some electronics unless the battery is disconected.
