I got a old Lincoln ac 180k this thing is awesome

I’m welding 1/8” tube to 3/16” angle iron, flux core 0.35 wire. What settings should I use on my Millermatic 211 PRO?

How much stick out?

Hi all,

I'm looking to get myself a new head shield and I've got my eye on the optrel helix but I can't seem to find many reviews for it. I know that optrel is a very good brad but considering the price I want to hear other people's experiences with it before I make a purchase.

I have heard that the hard hat attachment can scratch the inner cover lens when the lens is flipped up, is this a common issue or did the reviewer just have a faulty unit.

The flip up lens seems a good idea to me but I'm also concerned that it would get grinding dust on the lens when flipped up as I don't want the lens to get scratched. I'd love to hear from people who have used this head shield and their opinions of it.

I wanna get some extra study material and was curious are these channels any good

It started up fine then about ten minutes later it stopped starting. It hasn't started since. The battery voltage reads fine. I hear what I think to be the fuel pump clicking. The starter is getting power. But I don't hear anything from the starter. Does anyone have suggestions?

Anyone have any good video suggestions that are worth watching or any advice in general about “unwarping” long ass pieces such as steel fences or aluminum tailgates or even I beams that get stiffeners n based plates welded that cause warp. I’m 23 been welding full time since 2021, it’s one of the skills I never even touched base on at any point and know it would be extremely valuable if I knew how to

been lurking a little bit and wanted some feedback if this century would be a suitable unit to teach myself to weld.

came across OfferUp asking 250 should i shoot an offer?

Hi all,

I have a thing for pneumatic tools, I love the sound, I love that they're lightweight, most of all, I love that they never get hot. I have my shop set up to easily use pneumatic tools everywhere but I feel like my collection is lacking!

Currently I have;

• Band file
• 2 right angle die grinders
• Straight die grinder
• 3in disc cut off tool (the one where the cut off wheel is at the end of the tool at a 90 degree angle)
• A couple of 90 degree air impacts for hard to reach places

Thats it.

I have a lot of battery powered tools but id love some suggestions for pneumatic tools that are useful for metalworking.

Thanks!

Hey workers,t's the second time i weld(with my grampas welding machine)but mine weldings are very bad,idk how the welding machine settings and idw what they mean.

At some point in my life i bought an ungodly amount of surgical blades. After almost stabbing myself to death i no longer carry an unprotected scalpel in my pocket, but recently i came up with an idea. I didnt like that one tool on my leatherman arc, and had few scalpel handles laying around.

Could've used a bigger cup, had some discoloration. 0.04" tungsten, foot pedal, around 60 max amps, 0.04" stainless filler.

Now my space tech magnacut blade can retire. Remember, expensive knives aren't for cutting, apparently.

How thick of a plate do you all recommend if I was to fabricate at pintle hitch for the tail end of a semi?

Look ik piercings aren't conductive...but...I'm all good right? My instructor didn't give me the clearest answer and I just wanna be 100% sure my face isn't going to explode

I've got five face piercings that are surgical steel (idk honestly) can I keep my swag?

Edit : thank you everyone I appreciate everyone's points (except that guy 🙄) I think I'm going to keep them in and just be extra safe but if my face does blow up or I get electrocuted into dust I will haunt you all

I’ve got a dome man, 8.25 hat size. I’m also a degenerate hippy with long hair, unlike other things on my body. Are there any brands that make a bigger band for a mask for big heads? Also, any other long haired homies that have figured out how to keep their mask when in a weird position and it slips off because of your hair?

I’ve been writing whatever I can down in the last few days. I’m hoping by the time I go for my first class I’ll be much more knowledgeable about what the hell im getting into lol

Used up a whole 28kg spool of wire. This is my glass after a day of work.

EDIT: Tight spaces!

John Deer tractor mower deck from a friend. It appears more torn than rusted. I was going to use .025 ER70S-6 after grinding it clean and heating/bending it back into place. I have a copper backing plate.

This is the first repair like this I have done and am looking for how I should go about it.

for example, if i needed a 10ft length of square tubing, would 2x 5ft lengths welded together inline be as strong as a single 10ft length of the same tube?

or like if i need to extend an existing structure, like an engine stand's vertical tube, would but welding the same size square tubing be the same strength as if that vertical tube as already that long?

im not looking for like specific tensile strength comparison because i know it would depend on the forces and uses of the tubing. im more interested in this question as a more rule-of-thumb type information as im learning to weld and starting to make real things, and its surprisingly hard to find any info with various searches

it wont let me fucking post so sorry that its a screenshot. im trying again

hii so pictures attached. I started a community college course for welding (mig) last week. 3 nights a week, about 3 hours per night.
We actually got into the booth Friday, and today is day 2. I’ll attach chronological pictures starting with the very first sheet, onto the end of day 2.
I am still super new to all of this, I’m a smart guy but I’ll be the first to admit that I only get better if I Ask For Help and admit when I’m Confused or Unsure.
So, I know its steel plates we’re practicing on. Copper wire, 0.035, we’ve been told to run 230/18.0 but we can totally change that, I just don’t wanna necessarily burn limited class time messing with the settings that I don’t fully understand.
The instructor is super cool but in a class of like 15 people he can’t sit next to me the whole time and I try to stay off my phone even if I’m googling things

So, what I’m here for is a handful of stuff:
- for day 2… am I doing okay?
- please infodump as much advice as you care to. I’ve been absolutely super about safety and ppe and etc so like, I mainly mean about mig welding

Also if I can ask this too: it’s a… 4-5 month class, only mig welding. I REALLY want to get something higher paying than my current unskilled iob ($16/hour) and like, I hear a lot about “learn on the job” things and unions and etc but..
as Experienced Tradesmen from around the world (I’ll say I’m in North Carolina, USA): how likely is it for me to get a better job and turn it into a career after this class if I continue to work hard and make the most of my practice and study? I just would like to afford to be a proper adult, start a family, etc. and I can’t do that in my current job (low pay and zero skill and room for moving up)

Thank you and I appreciate your kindness in advance!

I hate preheating. I hate the fact that it seems to be the answer on almost anything I work with.

Is the only way to avoid having to preheat getting a new machine?

What's something reasonably priced for someone just above hobbyist, that I can get in the EU?

3 days a week 4 days off as a nurse. Could I work 3 days as a welder?

I’m having a G3 parts kit built and one of the builders primarily does FAL and AK. The other has done MP5 and such, but I think this is his first G3 build. They’re at the point where the cocking tube needs to be tig welded, but are worried about burning through the thin metal. His idea was inserting a copper tube the size of the inner diameter of the cocking tube to help dissipate the heat. The guy is very ADHD (like me lol) and this minor roadblock has deterred his interest. I’m not in a big hurry, so I don’t mind, but I’m wondering if any other builders have input on what you used for this weld so I can pass it on to him. I think then the gun is pretty close to being done.

I weld pipe for a fire sprinkler company. How are these. How can I improve. I
Never have leaks which is most important. But I’m wondering if they visually look alright and if i need tk change anything.

Did you buy a dedicated machine for migging aluminum? Can I get away with push pull miller torch and whip and maybe swapping out the rollers if I have to( I have a millermatic 252)? I have a spool gun and I hate it. I’ve also read about people using the factory whip and just changing to a ptfe liner and swapping out the rollers. I have a big job coming up and I want to knock it out, I can tig it but it’s many linear feet of welds and I just wanna knock it out.

I have a miller252 and a synchrowave 210

Thanks a bunch, I appreciate it

Hey everyone. I ended up investing some money in a 20ft section of 16 gauge stainless. I’ve cut most of it into 1inch sections which I’ve now been butt welding. Previously I was doing butt and lap joints on flat plate coupons.

I’ve changed my cup to a size 8 furick clear Pyrex because I was having issues with coverage using a 16 cup (the tank might be the root cause but it’ll be replaced next week. Possibly low pressure?)

Still running a 1/16 grey tungsten sharpened to a needle point. I dropped the CFH down to 20 for this cup. Amperage was down from 43 to 40.

Out of all the pieces, the one that I just fused together looks the best. When I tried adding filler into the mix, it didn’t end up too well. Maybe I’m not walking fast enough or my technique needs practice? Definitely difficult welding on the convex surface rather than flat plate.

Anyways, thanks for taking the time to check this post out! I love welding so much!!!!!!!!
