Customer Questions & Answers

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
Yes it can,,, very well,,, no problem But,,, I (personally) have always "disliked" 7018 because of it's spits/sputs/wavy arc/instability --If your new at this,,, you'd want the easiest rod not the most difficult rod

Customer Reviews

AC/DC 225/125 Stick Welder is rated 4.8 out of 5 by 41.
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.

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.

Rated 5 out of 5 by from Awesome "work horse" welder. This is a basic work horse welder. The DC mode option is great and this machine can dish out the spark all day long. I have high dollar welders in the shop, but I needed a basic no frills stick buzzbox, with none of the "gingerbread" found on other expensive welders. There's no need to have a stick welder with all of the bells and whistles on board if your a home hobbiest, farmer, rancher, metal artist, plumber, carpenter, handyman, welding student at a tech school or even a professional for home use. Unless your into production welding or ship building, this welder will fit your needs. For thin stuff less than 1/8" thick however, this and pretty much all stick welders is NOT for you. Stick is not intended for thin sheet metal under 1/8". Even then, use 3/32" 6013 electrodes on DC- for the thinnest stuff. Some say that the "tapped" amperage control is not as good or "fine" as a continuous setting like the Miller Thunderbolt or Hobart Stickmate. Well, so what. The difference in amperage adjustment is negligible. I doubt two welders side by side could tell the difference apart of each's weld beads when comparing their machine to a Lincoln AC/DC-225/125 machine. One I'll say is that stick welding does have a BIG learning curve to get descent (slag inclusion free) welds. Practice practice practice and watch online videos on proper technique and electrodes to use. Also, make sure you have a 50amp 240 volt electrical outlet installed in your garage. It requires a NEMA 6-50R type receptacle that your electrician will know how to install. Try to avoid the "30 Amp" "dryer" outlets. Sure it will work, but not at 2/3rds or full power when needed. Home Depot has a pretty good price on these Lincolns. Buy one, you won't be sorry (if you practice a lot)!

Rated 5 out of 5 by from By design, the DC side has finer amperage control. I am a retired Boilermaker pressure-parts welder. When I retired; I had 22 different welding certifications to my credit. I love this machine! You can weld a great number of different welding rods.308-16L on Ac & 7018 on Dc reverse are two of my favorites.

Rated 5 out of 5 by from It's a Lincoln what can I say I have been welding for 35 yrs. If your looking for a arc (stick) welder, look no further. This machine can weld up to 5/16-7018 (Low Hydrogen) and up to 3/16 Mild Steel. You can even carbon arc (back gouge) with 1/4 inch carbon rod. If you have an air supply that is. Yes, there is bigger (amps). But if your not building a ship. This is the machine for stick welding!!!!
