Not according to Lincoln, and my hunch is that their engineers and metallurgists know better than anyone here.

From Lincoln spec sheets:

7018
Elongation: 25-37%
Charpy V-Notch: 121-332 J at -20°F

6010
Elongation: 22-29%
Charpy V-Notch: 51-93 J at -20°F

A pretty big difference, with 7018 being FAR more ductile/"tough."

I've used two engine drives 45 years apart. The first left me in awe. The second I make do. The Westinghouse monster blew 6 ply tires driving on paved road. it likely used 5 gallons per hour. It made me think I was a weldor! My Bobcat 250 is OK. I've never made a weld I was proud of, but Howard does make welds I'd like to claim. It seems all welds are too splattery, and when I want voltage It starts to accelerate. All stick machines make flat welds, out of position wants low voltage, high current. This capacity can be measured on a scale. There is no substitute for cubic displacement. A struggling engine starts welds poorly.

Yep I have seen that.
In an experiment where I ran my little 110v stick welder off a little 3kw generator it was bogging the generator down with a 3/32 rod, when it would slow down the bead would stack up, you try to weld in a manor which doesn't bog the engine down which makes a crappy weld. Then if you go back to trying to weld normal the engine would bog and the weld would look cold and like crap.
With my little 5hp engine driven alternator welder same deal. Put a 1/8 inch 7024 on it and set it for max power, the engine starts to bog and the 7024 starts to stack up. Stretch out the electrode gap to give the engine so relief and it gets spattery.

Re: Best portable engine drive welder

I can run 7018 with my eyes closed. I don't have a rod oven and low hydrogen are more sensitive to rust, oil, moisture, paint and a number of real world conditions. I could never get that oily cylinder clean enough to take a good weld in the field. Those are actually 6011 beads and I never said they look good. It was -10 degrees and no auto dark hood so the rod kept sticking a lot of re-strikes because of contamination deep into the metal grain. It's still holding after 2 years. The first one only lasted 8 hours but it looked really nice.

Well, to be honest, it looks like you run those 6011 beads with your eyes closed.
I'm glad your happy with your multi quip engine drive welder. But I've yet to see one on any type of code job welding structural or pipe and they certainly aren't no sa200. You don't see any any arc control dial on any Lincoln sa or SAE machine because they don't need it. An experienced operator can use the coarse and fine amperage controls to accomplish this.

It's funny to see some that welds as bad as you criticize other peoples work. This is a field repair. It's not a permanent fix. It cost $500 per hour to have crew standing around waiting for a down machine. It took less than 30 minutes for me to grind and weld that cylinder in -10 degree weather. And I couldn't see for **** at -10 weather steaming out my helmet. It was a 30 minute repair that lasted over 2 years. We have purchased a new cylinder but were waiting for that one to break before tearing it apart. The shaft has bent slightly but it never broke.

You obviously missed the entire point of my post. A fast and dirty repair can be made in less than ideal conditions. Also cold weather may have been a factor in why the 7018 weld failed.

I was just using what he had there. I didn't want to drag my welder out there. I like 6010 5P+ the best for this type of application. Better toughness and ductility. This arm is subject to too much shock forces and 7018 is too brittle.

I'm not here to start a pissing match.
But, when you post statements like this, your credibility pretty much goes out the window.
Cold weather? I live and work and weld structural in temps down to -40. We work through it. And we don't blame poor welds on the elements. Those excuses don't cut it with the weld inspector.
I'm glad you dig up some pics of when I was starting out in the trade and learning to run stick vertical down. That must have taken you some time. Takes me back. Thanks.

Re: Best portable engine drive welder

69sa200: it is not my intent to cause trouble.

you posted a thread. you got some useful information out of it from some helpful fellars. you dont believe them and are trying to argue with them...

i love helping people, but it is hard when they are talking about yellow backhoe repair and then bring up pictures of red. . . .stuff to prove a point.

not criticizing your technique at this point, but your logic and reasoning i think are where we should start

7018 has way better ductility and toughness then 6010, you should really read up on the electrodes you use before you make false claims that mislead.

Re: Best portable engine drive welder

I have one and its a good welder. I've mostly used it for scratch start TIG and it has a nice arc. If that one has an onan engine like mine does, the parts can be expensive. Also the AC power is 50Hz. Most things now days dont mind but you could still screw stuff up if your not careful.

Cant comment on the SA-200 type generator. Duane would know though if he sees this.

Re: Best portable engine drive welder

Lots of misinformation on this thread. Never use a cell rod (6010 ) for anything dynamically loaded, it will fail sooner of later. its for pipe roots and filling other gaps. 7018 has way more ductility and thats what u want for equipment when the welds are subject to load cycles. Those hammer tests prove nothing.

Re: Best portable engine drive welder

I have two Lincwelder 225's, both have Onans. Both came in kit form. Onan parts can be found at reasonable cost if you look around. I also have a Weldanpower with a 16 HP Briggs, and an old Hobart with a THD Wisconsin engine, all have/can be rebuilt inexpensively if wanted. Whatever you choose or like.......... Good luck!

But how well do they perform? I was using my cousins Miller Bobcat 250. The arc was very difficult to adjust. The spatter was a hot mess and and if you lower the amperage a touch the the rod sticks to the work. With the Multiquip it has something like a hot start feature and if you break the arc by accident you can get right back in and it re ignites. Easy starts no sticking and low spatter from a 250 lb portable welder. How much does the Lincwelder 225 weigh?

The multi quip is not like a sa200 at all. The sa200 burns 6010 real well.
7018 blows 6010 out of the water in terms of strength, ductility and appearance. If you can't make that happen with 7018 then you don't know how to weld with it.
Your multi quip beads in your photos don't look very good.

I'll second that......."ANYBODY" that compares an Sa-200 arc to any other welder , is full of ****..... There is no mocheen that even comes close.....sorry to disappoint you........
