Anything welding

looks super badass dude!! You’re making quick work of all of this. I’m having fun watching it

 

Thanks brother. I appreciate it. I figure if I'm going through all this trouble, I might as well make it legit.

 

Please be careful. My brother in law burned his truck up this last weekend.

Welding with flux core and a hot ignighted some sound deadening material. Cab corner and up the inside of the cab burnt pretty good...stinks bad too.

In glad he was there to put it out. This situation is my biggest fear. I hate welding on vehicle sheet metal!

 

Made some feet for the plasma table.

What can I say? Little progress is still progress. Amirite?

 

I'll weld a 3/4" nut to the top of the stud. I don't feel like swinging an 1 1/8" end wrench to dial down those bolts.

I have 4 more if those big nuts to use as jamb nuts.

 

You ain’t lyin. When I was tubbing my truck, I started five fires in the cab, on one side alone. After catching the first two I voluntold my wife she was on fire watch.

 

I often compare it to learning to drive. Anyone can “learn”. Some get it right away, some take forever. The more you do it, the better you get. Once you’re comfortable, then you can get into some advanced shit: I’d say expert tig welds are the equivalent of a perfect toe-heel shift with RPM matching goodness.

 

Okay need some help. Not sure what’s causing it but getting some porosity in my welds. Only happens every so often but no real pattern or reason seems to cause it and it just goes away sometimes. I changed tips. Cleaned the nozzle and cap.

Can to much/to little heat or to fast/slow of wire speed cause it? Or different wire brand?

Machine is a millermatic 215 on 75/25. .030 wire. Welding mild steel.

 

Maybe something going on with the shielding gas? I had to change the diffuser piece or whatever you call it that has the little gas orifices, that the tip screws into.

 

What are you welding when it happens?

 

1.5x1.5 square 120 wall tubing and the same square tubing to 1/8 hot rolled sheet metal. And the 1.5 to my trailer which is 3/16. Also did it while welding the 1/8 on a but joint to 1/8. Never had this issue before doing drive over fenders on the trailer. Used the same wire and bottle on rear axle and frame of my tacoma with no issues.

I thought maybe the gas was getting blown away by a breeze but ruled that out after using barriers and welding on non windy days.

 

I had a similar situation and I ended up diagnosing it as contaminated wire. Dirty shop conditions and filthy gloves while swapping wire ended up buggering up the tube liner as the wire passed through the tube to the gun. I learned a trick online to fold over a small paper towel and dip it in a little acetone and use a binder clip to hold it semi loosely over the wire just ahead of the feed roller in the machine. You’re not clamping the wire more like clipping the paper towel around the wire. The paper towel dries out quickly but it keeps wiping the wire clean before it passes through the rollers to the tube and gun. I also gravity fed some acetone through the feed tube of the gun with a funnel to clean it out some. I don’t really know if it was completely necessary but a lot of dirty acetone came out the nozzle and I never had the problem again.

 

Hard to tell from the pictures what weight casters are those ?

Better to go to big then to small .

 

Speaking from Experience Fires are bad!

Even more so when the Fire Company has never lost a foundation since they bought the first bucket .

 

Have you wiped this steel off? I’m assuming it’s new steel, it may have some oil on it in places, just a guess. What’s your argon gauge set to on the low side?

 

Subd.

 

I honestly don't know what their rating is, but we routinely move 3K loads with ease. They are big and heavy and they have a cool pivot lock feature to switch them from swivel to fixed direction.

 

Are both ends of the square tubing capped. If so you need a relief hole. When welding tubing that’s gonna be capped on both ends you need to leave the air inside the tube a place to go, or the pressure will build up and blow out your welds.

 

learn something new every day... No I gotta steal "borrow" some binder clips from work.

 

I took the opportunity to clean out the rollers and all internal parts with acetone too. Apparently a welder gets super dirty after 10 years of use.
