what is the diffrence between ac stick welding & DC stick welding7

Asked by: Anonymous
DC welding is better than AC welding. It costs more to have DC option on your machine because storing a DC voltage is in-effecient and costly. Batteries(which are just huge capacitors) have flaws like internal resistances and worsen over time. It is inevitable that the DC function of this machine will fail at some point, and it will need to be serviced and repaired. On the other hand, DC welding cancels out the effects of switching any voltage from some value to a different value in a period of time(hz). Different metals and even different shapes of metals will have some unknown "resonant frequency value". Even the direction and distance of the electrode your using effects this resonant value. If that resonant frequency value happens to be close to the frequency your electrode is cycling current at, then the properties of inductance (ohms law) say that resistance is at a maximum at resonance. If there is increasing resistance at certain frequencies then current cannot flow through the metal as well to heat it up. Welding, is heating two pieces of metal so they melt together and become one piece. With direct current or DC welding you don't have to worry about the thousands of reasons that could be the cause of inductive reactance or capacitance because they have no effect on DC, because DC remains at the same voltage and it follows that DC current remains at the same amperage. Resistance does not increase and limit current flow through the metal, it is flowing as steady as your hand can guide the arcing electrode and that's why I would assume there's less spatter and such. You're gonna want to pay 200 more dollars for that DC option. If you don't, your welds will un-predictably not look good at certain times and you'll never know the root cause, or how to iliminate it from happening again, unless you're like some electrical genious. On the other hand, the effects are very small in some situations that you may be able to be ok with them. But if you're gonna weld metal for someone else to use and expect to recieve compensation maybe, then probably you'll have to have the DC option in order to create them as good as someone other person who flipped the coin up front and has no clue what I've blathered about here.

Can a 7018 rod be used with this machine? If so what setting should be used?

Asked by: Johnson
"Sticky Rod?" A good starting point for use of a 1/8" rod is 115 amps then adjust up or down, preheating with a torch can also be beneficial. If your blowing holes adjust downward, if you cant maintain an arc adjust upward, obviously the same holds true for more or less penetration. One caveat, 7018 , low hydrogen rod as all low hydrogen rods, is frustrating for beginners to use, best used on DC reverse polarity. Different manufacturers rods are easier/harder to work with but all will give good results if your skills are good. Practice here is key and remember "frying those eggs," welding is an inexact science.

what is the thinnest metal it can weld?

Asked by: newbie
If you limit the current more by adding a material with more resistance it will take away weld heat for thinner materials

AC/DC 225/125 Stick Welder is rated 4.8 out of 5 by 45.
Rated 5 out of 5 by from Years of reliable service I borrowed one years ago and when the owner needed it back I was so addicted to it I had to buy my own. This was about 1980 and I use it several times per week. It has always performed flawlessly. The only flaws are no wheels, either buy the kit or add your own. I made a small cart for mine. And the fact that the ground cable is short. That is also easily rectified. I made a 50 foot extension cord for the power so I could wheel it anywhere in the shop with ease. Most of the time I weld 1/8" to 2" thick steel, always in DC mode. I've welded aluminum & cast iron with it several times with great results. I'm sure I could also weld stainless but have never needed to. I've even taught many beginners to weld with this machine and it handles abuse with ease. Can't go wrong with this one.

It's sure nice to have DC and really love this thing. It is performing flawlessly. If you're thinking of getting a 'tombstone' I think it's worth splurging to get the DC also; you won't regret it.

Rated 5 out of 5 by from Excellent Price I read the reviews before purchase and was a little hesitant but finally purchased. This is a great buy probably saved 350.00. I contacted HD and they informed me it was a new welder not refurbished and it did have a small dent or 2 in cowling but a dead blow hammer straightened right into place. Don't know why they had such a great price I am sure there is a story behind it but for a welder that will sit in a shop you can't go wrong. Came quickly delivered to house excellent contact with HD personnel. Plus I received 12 months interest free to pay off, If you know your welding you will know this is a great buy.
