TinLizzied, I would definitely upgrade the breaker (and wire) to at
least 50 amp, and preferably more. Then you can have a lot of choices.
Yeah, I've thought that 30 amp circuit was a little low unless I went
with an AC tombstone or something similar. Funny thing is, I've never
welded with AC. I would like to find someone local with an AC stick
machine so I can get a feel for it.
I like the idea of no arc-blow when using AC, but I've heard that the
rod and positioning choices are limited. This true?

Nearly all of the small ship yards in S.E.A. are using buzz boxes to
build barges and small ships - tugs, service vessels, etc. You see
them scattered all over the yard wired up through long extensions.
And 6011 is the most common electrode you can find over here.

I can comment...
AC and DC on weld outcome. Here in UK at college - so every electrode
is 6013 - learning vert-up T-fillet using root run 2.5dia 6013 then
capping with zig-zag weave 3.2dia 6013 (the college standard method)
Essentially, found that could hold a shorter arc and get a flatter
bead on DC. With AC had to hold a slightly longer arc length so
didn't short-out the weld as crossed the more humped root.
And smoothness and general aesthetics of the finshed DC weld get
higher rating than for AC weld. But not by much. And of course,
college is not the real world. A good "tombstone" AC welding machine
is very good - and there are a lot about. Last thing you want is a
bad cheapo inverter DC welding machine when you could have a sweet AC
machine (???).
Here's the details:
On DC, could make the root-run absolutely flat - doing a "shimmering"
weave never more than the electrode core wire still overlapped the
corner to flatten the root run (a flat root bead makes the capping
bead much easier). Then with the capping run, could hold a really
short arc length, so very accurate focus of where the metal and heat
is going.
Found the 6013's DC do run better on DCEN (the "college standard") -
tried burning a few bead-on-plate and timed - came out to-the-second
identical burn time, whereas DCEP was all over the place. Rods so
happy on DCEN, stayed with it. Of course, for 7018's and 6010's,
opposite is the case - DCEP is where it's at. Found can do the
"college method" of 2.5dia root, 3.2dia cap all on same amps with 7018
DCEP. |

What do you consider "home use"? Around here that includes heavy-

To me the difference between pro and amateur, home and commercial, is
that the pro has to make the weld wherever it is, while the amateur
can limit themselves to jobs they know they can handle, and work small
enough to roll over to weld flat, and send out the rest. The pro needs
a capable and dependable machine, the amateur can get away with a much
cheaper one.

I'm a full-time weldor at a naval shipyard, DOD-civilian WG-10. I get
enough of welding my butt off at work, I ain't gonna do it to myself at
home!
"Home use" for me means I'll burn about a half to one pound of wire a
month at most, I imagine. I simply want the capability to weld at home
for building small projects or repairing the same. I would like to be
able to weld os, hs, cres, and aluminum. Will an AC "tombstone" give me
the wire choices for those materials? I'm not even sure if there is a
stick wire for Al. All we do in the shipyard is tig on cres and Al.
Kinda funny- I'm qualified to weld using smaw, fcaw, gmaw-pulse & spray,
gtaw, on many materials including: os, hs, hy-80, cres 300 series, NiCu,
CuNi, and more, but I've never struck an arc on aluminum. I'm used to
having big machines running big wire and sucking lots of amps. This
"home welding" is more complicated than I had thought....

Re: Aluminum stick welding
I'm sure that everyone with a stick welder, arc welder, SMAW welder, or
DC TIG welder has wanted to weld aluminum at one time or another. The
main problem with this is actually information, not technology. Most web
pages and forum posts state that a MIG or AC TIG welder with argon
shielding gas is required to weld aluminum, which is not accurate. What
should be stated is that AC TIG is the slowest, cleanest, and most
controllable way to weld aluminum, which makes it especially good for
welding thin aluminum. MIG is much faster than AC TIG, but it is not
nearly as controllable because you cannot melt the base metal without
adding filler metal. MIG was designed for fast buildup and continuous
welding and it is still relatively clean because of the shielding gas.
Neither AC TIG or MIG can weld aluminum in breezy conditions.
Stick welding aluminum is possible and actually works better than I
expected. I used 1/8" Harris 26 Aluminum Welding Electrodes that I
purchased from Cyberweld.com. The electrodes use different flux than
more common steel electrodes, but the process is basically the same.
They recommend DCEP/DCRP, which makes sense. AC TIG is able to remove
the oxide layer on the base metal during the electrode positive portion
of the alternating current. DCEP constantly removes the oxide layer from
the base metal while the electrode flux keeps oxides from forming on the
electrode metal and the molten pool. The flux protects the weld as it
cools and forms a protective barrier, which works great even in windy
conditions. They key is to move faster than you would with a steel
electrode and not much weave movement is required since the aluminum
flows better than steel. I welded a 3"x6"x60" aluminum box section out
of 3"x0.125" angle for a storm grate extension and used less than 1
pound of electrodes. That works out to 60" x 4 seams = 240", which would
have used quite a few TIG filler rods and a significant amount of argon
from my 40cuft bottle. The following video shows the basic process and
my newbie welding skills. This bit of welding was done with my Everlast
Super250P on a bottom side of the grate extension near the beginning of
my learning curve. My welding and my welds got better as I progressed.
Here is the video:

Gunners note: Stick welding aluminum requires you to move FAST as the
rod burns down very quickly. Nearly all Aluminum rod will work fine
with AC though most recommend DC-

High frequency boxes dont waste much .
At full output , some waste less than 5% , but old
60 cycle , heavy transformer welders can waste 30% .
This makes it better to hook welder to 5500 Watt gas genset .
These low cost high freq welders are compact , light wt and
only lack proper air flow to cool transformer . DIY . tiny fan
placed directly over feritte transformer .
They output is controllable , so you can use them with a
wirefeed . Same for MIG stitching and spotting , the transistors
are easy to control . But 60 hz welders need expensive SCR's
on input 220vac .
Some machines are unreliable . Its up to you to study and gain by
experience , by opening up the box , and learning electronics , which
machines will last . Longevity-inc , model 518 runs output current
thru 2 relays . Wont hold up . Need a big switch to handle big
amps .
Transistors are stressed between 2 forces , a heavy heat sink
and the screwed down PCB . I got litt;e use from my 518 .
Simon K refuses to warranty it .
