Monoprice is getting into knocking off the Yeti coolers.
Search Results
Nice find! I've never been a fan of YETI price gouging and marketing. The lack of competition for years forced many to pay ridiculously high prices for better performing coolers. Eventually rotomolded coolers will become even more common and YETI and the other big names will either adjust or just fade away.
 
For those with auto-darkening welding helmets, do yourself a favor and get a traditional fixed-shade helmet. When I was doing my research for welding helmets, I just couldn't understand why someone would prefer a fixed-shade to an auto-darkening. I purchased an auto-darkening helmet that got great reviews on Amazon. I've been welding with it for almost two years now. I've never had consistent welding performance and always thought it was an issue with experience rather than the equipment (Hobart Handler 180 220V).

I was in the Home Depot the other day and noticed they revamped their welding accessories section. They had a Lincoln fixed-shade helmet for $41. I thought I would give it a try and if it didn't work out I would just return it. Last night in preparation for welding my bumper, I practiced with the Lincoln helmet. This was a true eureka moment for me. Obviously setting up the gun is more difficult but once the bead is started, viewing the weld puddle is crystal clear. I could see everything I was doing wrong before. Previously with the auto-darkening helmet, the arc was too bright and the surface was too dark. Adjusting the shade either made the arc too bright and the surface slightly more visible (BAD) or the arc less bright and the surface almost black (BAD). With the fixed-shade, I can see both clearly. When I'm making loops, I can see the edge of the puddle perfectly. I put down several practice beads last night that I am actually proud of and now look forward to welding my bumper when before I was quite nervous.

NICE DUDE!!! That's what I'm talking about!!

I think if we were made of money and could afford the really expensive auto darkening helmets the issues you describe will go away. Until then, fixed shade welding helmets are the way to go :D

Another thing about the fixed shades is that you can get different shades to suit the welding amperage you're working. For example, a 200A weld would use a darker shade than a 50A weld. You can get away with a shade right in the middle, which is what I do, but there is granularity if you want it.

Also, sheetmetal is SO MUCH EASIER with a fixed-shade because you can see the heat in the surrounding metal!!
 
FYI, no fires please

All burning permits canceled in Charlotte, outdoor burning prohibited
 

Definitely take this to heart they think the one by my house was due to an illegal camp fire along one of the hiking trails and several of the other ones out here were started by cigarette butts the I am one ridgeline away from the fire reaching my house now so if the wind gets really bad it could be here fairly quickly I watch the smoke daily coming over the mountain from the Party Rock fire and we now are getting updates daily on possible evacuation.

Yeap, there is a giant gap in auto-darkening helmets $40 - $110 and then $250+ . My helmet cost $89 and has an XL view.

Dumb question... I'm sure... but does this mean we won't have a fire at The Christmas Party?
 
we shall keep some buckets of water and extinguishers nearby..

Local article in our paper said that it didn't apply to fires within 100' of an occupied dwelling, the barn seems like it would be occupied ;).... said it's up to the local fire marshal at that point.....
 
Is it worth the risk?

Perhaps this might bring the situation to focus

Never said I would burn anything - haven't burned anything at our house for years outside..... just pointing out what the local paper said.
 
I was speaking in generalities, not directly to anyone. Believe me, if I was addressing someone directly there would be no doubt.
 
No worries :)
 
REALLY!

This guy (who teaches in my county) calls himself "Captain Physics" and misses BOTH of these basic questions that another teacher posted on our county list serve. Bad enough that Teacher #1 didn't have a solution but WTF. :bang::bang::bang:
(Sorry. Rant = Off)

I am having trouble explaining these two questions. The first We understand that It is newtons 3rd law that says there is an equal and opposite force. But the student in frustration says, THEN WHAT MAKES THING MOVE!? Can someone help me with explaining this.

#23 I got E initially and was about to accept B as an answer because of the wording of the question, but A is correct. HELP!


3) In order to get an object moving, you must push harder on it than it pushes back on you.
A) True
B) False

Answer: B

23) A 6.00-kg ornament is held at rest by two light wires that form 30° angles with the vertical, as shown in the figure. An external force of magnitude F acts vertically downward on the ornament. The tension exerted by each of the two wires is denoted by T. A free-body diagram, showing the four forces that act on the box, is shown in the figure. If the magnitude of force F is 410 N, what is the magnitude of the tension T?

A) 271 N
B) 235 N
C) 188 N
D) 376 N
E) 470 N

Answer: A


Response:
For Question 3 . . . .You would have to push harder to get it to move. In order for an object to go from not moving to any motion - it must accelerate (if only for a moment). Or it wouldn't move at all.

For question 23 - I also got something close to answer B. Since they are the same angle . . the upward force will be 2Tcos30 = 410 . . .so T is about 237 N.
