they don't have a lot of room around the core support ....you may have to two-piece it ,or if you use one for a super-duty truck...add spacers behind the bumper, some ambulances have an add-on inter-cooler under the big step bumper (out front), you won't need that much room ,but two and a half inche...

Sounds like the chinese were tryin to keep the cost down-they obviously couldn't afford a translator :p Cheap bastards . . . . if you want a cheap laugh ,...go to "harbor fright " or even a regal tool bin....pick up any tool and read caution label very closely.....you will find statements...

..... I use .045" er70s6 for filling holes (cleco holes and the like) or where there is significant rust you can't remove and .035" or 1/16" er70s2 for everything else. for 22ga, I'd stick to the smaller rod. .. .. raw mig wire ?; or do you drag it through a piece of sandpaper like a...

intake pipe ? like 3" hot dip galvanized 14 guage wall tubing?...you should sand that shiny before you do ant weld on it . . . . .try a piece of 3/16" mild steel set up for a lap joint,set your machine DCEN, #6 or #7 cup, 3/32" size 2% Th or La tungsten-ground to a "bloodletting&...

you probably had about as much arc inside the machine as you had on your workpiece!...i have done the same thing with my 225 ac, I later opened it up to dust it out, and saw carbon tracks on the edges of the contact points....it'll prob. be fine as long as you are careful not to do that too much mor...

"farm jack"....you live near some pretty smart farmers if they have Hi-lift jacks on the trucks, you see them in all the 4x4 magazines...they are super useful for pushing ,lifting and pulling.

pretty nice work!

rural route mail box,100 watt rough service bulb through the back and a wrap
of fiberglass over the top....it will hold a 50 lb box of 7018's and a 5lb box of6011's on the side of that one....not every one needs a refrigerator full of warm,dry welding rods....

Here's a trick: If your hot water heater is in a closet, keep the rod in the closet on top of the heater. It keeps the rod dry by the same principal as the gun safe "Golden Rod" type heaters, that is by being a few degrees warmer than outside the closet, moisture is pretty much displaced....

i was thinking "screw-head",....pinhead's hillbilly cousin that is in charge of purgatory!

it's an exotic metal, you are probably looking at $7.00 a rod for 1/8 fillers....
plus shipping + hazmat fees (magnesium is volitile/flammable)

purging takes time, time costs money, but corporations like to save money,so
you should go to PraxAir....i believe they still have a "Purity guarantee" in effect...
...if not,change your tank and purge your torch line!

That looks like a piece of cast something, the way the right side looks, like it was broken off of something. Could be the problem. that's not "broken"...it's newbie torch cutting,you have got to angle into a sweep {the torch towards the end of the cut) when you cut thin metal.}...it'll m...

.what is the root opening?
.are you starting at a tack?
.amperage?.

.the size of the pipe really doesn't matter, unless there is a breeze blowing through it.
.thickness?

.stickout?

the best aluminum welding from the little lincoln, without a freek box (high frequency) is going to come out of a Prince spool gun or similar unit...you may need a"torpedo" box if the Amphenol plug is different but you won't need a freek box...you will need:(your lincoln ranger),pure argon...

possibly a pulse cycle remote?

the "butt" is the thickest part of the can, if you wanted to know why it welds better..
.
...i have to post a pic of some of my razor blade welds, i went through half the box before i got a pretty pass...

take it to a miller service center, i don't know another place that has a "Variable Load Bank" or a Variac ,
would you also have to put a heavy load on the power outlets?

does it have baffles inside ?
the temp outside won't affect you as much as wind.
skip weld the seams.four to six inches between starts and stops.
weld a few bungs ....1/2" female pipe...so you can flood/purge the 'toon before you weld.
now you know what i know.

mineral spirit flush ....a parts wash pump and an extra barrell.

I don't know what that guy is talking about .. you're basically wasting your time and money at a community college. You get second rate instructors with sub par carriculum. Lincoln is a nice school if you are looking for a fast track course on general basics of welding. . . . I personally graduated...

buy American ! here's a good inverter ,i use mine to tig stainless...the gas bottle /deposit on a 125 cu ft.bottle cost as much as the welder !...(...thermal dynamics is in St.Louis ,MO...)

steam it!...there is a "pot metal" rod ,its got a square profile like lead rods and cast iron rods...we have a local supplier ... www.joneswelding.com they are here in the southeastern u.s. -tallahassee -thomasville-albany-cordele

that appears to be a contamination issue ?...I have always used pure tungsten for any aluminum work...also notice that you are at a pretty long stickout....how much of it is showing pre-weld?...if you set it up slightly recessed you get a "flashlight arc" ....but, i am no expert...

Thermal Dynamics...{st. Louis,MO,USA } ThermalArc 95 s... I managed to snag on from Indiana Oxygen Supply for $480.00 with the TIG lead,regulator, and case....it welds just like the Miller Maxstar at my old shop, except for the "autolink" power input feature that lets you run it on 230 v. ...
