Yeah, the clamp was pinching it together, but it was shot.

Slow week this week, but I have been working on this air manifold for the shop. 20 drops. Not very fun sticking sch40 to .065 tubing. 
Quick Q:
A friend was selling me on the idea, higher amperage, breaker, and wire to the welder - beyond the base welder specs may increase duty cycle? Is there truth to this, half truth, or no truth?
For instance, a Millermatic 211 runs on 30amp 10 wire. Bumping it to a 50amp 6 wire will not only increase options (quality plasma, larger welders, etc) the expressed thought is the duty cycle will increase. The 211 duty cycle is great as it is and not an issue. Curious if there is truth the comment.

I dont believe it to be a noticeable difference but I could be wrong. Never personally needed 50 amp for any of my projects
What particularly are you welding regularly where you need 50 amps? Not a lot of ship building going on in Montana.
More for the purpose to flip over to a commercial level plasma cutter setup. In the mean time my 211 does a 3/8 first pass fine.
At new location and about to run wire, etc. Don't want to limit though also, 6-8 wife is $$$.
Feeling it out. I've run 30 amp at prior location. I hadn't heard the duty cycle aspect before. Figured if so, someone here might have a bead on this info.

Duty cycle is internal to the machine. The only thing a bigger breaker could help with is if the machine was topping out early (we run into this sometimes in plants when we're running off 110, sometimes the machine will let you set more amps than the wall will provide, but it won't draw enough to pop the breaker). If you're drawing full power on your current circuit, upgrading it won't change anything except allow for larger machines in the future.

Now that I have the missing steel filled in Im going to grind the welds down and weld in some extra re enforcement and call it a day

It's tough to see the repair but unless the welds are interfering with something, I would leave them be. Extra reinforcement around a weld is always good.

Plan is to grind them down flat and make sure its square. Then I'm welding in some plate to stiffen it up some more at the wear points. As you can see in the before photo that thing was pretty chewed up.
Basicly all I did was filled in grinded down flat to make sure the weld worked and laid a bead along the top of what got repaired. The other got two short beads as the bucket had a lot more material missing in the corner.

I guess I'm not seeing the perspective of the repairs. Maybe a couple pictures not so close up? In the end, your the one that has to be satisfied with it and the Bobcat really won't care!

My son wanted to make a few extra bucks over spring break so I let him weld angles and install handrail cables around a job site.

There's some pretty ugly welds on the 2"square support tubing.

Yep, I'll make no claims that they look good. But they were done hanging off a press with a huge (3/32 on 1/8 wall) gap to fill and they're plenty strong. You can see which ones I was able to get a good support point on and had a good fit on.
Beware the internet welding inspector. mtmuley

It's a valid critique, they don't look great. Appearance matters in plenty of welding applications. Hopefully in 5 years I'll be able to make a weld like that look just fine. But at the end of the day, it does what it needs to.
All fun and games until someone forgets to drop their helmet and sees a flash everywhere they look for the next few minutes. Haha!
Have an aluminum welding hobby job set for tomorrow with the spool gun.
My boat ladder is mainly for climbing aboard the boat, trailered. Need a wider and longer ladder.
Plan to fashion it in some way to attach to the existing ladder that will pivot upward while boating and drop down to climb aboard from water.
Pics incoming. Rarely pull the spool gun out though a few test runs and it's back to the glue gun mig preset habit, just a bit faster for aluminum
