DC help

[deereman75]

Well I just tried out my new longevity stickweld 250, and I love it. It welds very smooth, and is so quiet. I am totally lost on the settings though. It seems the amperage needs to be differnt for DC, and I have no idea what settings I should use. Then I have the arc force and surge control. I think the surge control is hot start. I have no idea how to set either of those. Any benchmark settings would be great. And also maybe give me some idea of how to set the arc force and hot start.

When tacking open root joints, I turn the hot start down real low, or it will blow holes in the joint. For all other welding I'll stay around the + 7.0 to + 8.5.
The arc force I turn all the way up for open root joint welding, with 6010 or 7018. Generally when running 6010 I like -2.0 this gives me the stack of dimes look with out even trying. For 7018 most of the time I run the arc force on 0.0

Far as heat, DC with be a little colder than AC.

Ok thanks, that helps a lot. I think the arc force adjustment of it is only from 0-10. If the weather clears up, I will play around with it some more. I hate welding in the rain.

Oh you're missing out on all the fun! Put your rain gear on, go outside sit on a cold beam and start welding. Make sure you're bent over at the waist, head down, and let the water run down the back of your neck. Make sure your belt is fairly tight or you'll get your underwear wet. This makes it very interesting to see, because when the rain is running down your back, it is also running down your face dripping into your lenses, in just a few minutes you'll have 4 or 5 arcs to look at!:laughing:

Oh it will happen to you. It's just a matter of time. You gonna expect them to drag that broken down bull dozer into the nice warm shop so you can weld on it? Ain't gonna happen buddy, you'll be out in the field laying in a mud puddle in just a few short years!

Ha Ha yea. I just want to avoid working in the rain as much as possible for now.

Right on the button Shield Arc! You haven't experienced life until you have layed on your back in the mud and pouring rain and welded a piece of broken "junk" for some one, and when you've finished it stops raining and they short you on money. . . .John

You don't think I drag the leads out in the pasture while its pouring down rain to reminisce do you?

I have no doubt that many people have welded in the rain. But this raises the question of how safe is it?

What is the safe way to weld in the rain or otherwise damp conditions?
