Anything welding

Nice design!

 

Definitely agree here...

I frequently have to weld inside of wood framed buildings. We have to weld to structural steel that is sandwiched between wood framing. The steel is either flush or recessed to the Sheetrock or shear wall. It's always unsettling to smell wood smoke in a near-finished building.

I always have an extinguisher and a spray bottle filled with water within arms reach, and fire watch doesn't end until an hour after the last arc.

When I was teaching myself how to weld, I made a temporary table out of scrap unistrut and (4) 12"x12" 1/4" plates that I tied together with 1/2" square stock spaced 2" between the center to be able to clamp work to.

It's worked pretty well for practicing but it's not as stable of a surface as it should be. I'll see if I can find some photos.

 

Welded open root 7018 for the first time today, 3/8" plate, 37 degree bevel, 1/8" land, 3/32" rod.
Ran it at 75, 77 and 81 amps, still need to go a little hotter.
Ignore the slag, i didn't bother thoroughly cleaning it because it was going to get cut again to use for 6010 open root.

 

Try not to get in the habit of not removing all the slag just to help enforce the muscle memory .

Atl east till your lucky enough to have a helper to do it for you

Depending on just what code your welding under one slag inclusion big enough is considered a failed weld most jobs are 3 strikes your out have a few to many .

It is back to putting floors in garbage trucks and trailers

 

Can anyone suggest a good starter welder for a learning person who doesnt want to invest a 1000$ to start with?

 

Hobart handler is a great starter unit. Actually, it will do 90 percent of what you will ever weld.

 

Thanks!

 

I go with Hobart Handler line as Well !!

Not a bad Hobby welder for the $$$

Just do yourself a favor and don`t run those tiny 2 pound spools made for spool guns

Nothing but feed issues

 

I think i will go with one of those when the time is right for sure.

 

I have the Hobart handler 140 running co2 as a shield gas and while others have good success at nice looking beads, I find I am far better using a AC stick machine. I guess I need more practice since I have only run a few pounds of wire through it.

Most use co2/argon mix. Why straight co2?

 

CO2 actually runs hotter and penetrates more at the same heat setting vs using C25

 

Since I stock C02 for beer brewing...it is handy and not stock an additional gas

 

I was wondering about that. In that case, carry on.

 

Few little passes... mig & tig... have to search around for more rescent stuff but this was about 1-2 years ago
Tight stainless passes allitle less than 1/8" width

 

Hetkind There is a real difference between Beer CO2 and welding grade CO2 unless your buying Your CO2 at the welding Distributor

If you can lay good welds with AC stick Mig should be simple.

What kind of issues are you having ??

 

Some recent stuff

 

I get all my gases at my local Holston Gas distributor, and they sell the same Co2 for both beverage and welding application. My mig welds with the little Hobard 140 handler either glob or burn through on sheet metal. However, my buddy Gary who welds daily, makes beautiful welds on the same machine and materials. So I need to practice and improve my technique.

However, my project this week is to put in a new dedicated 100amp circuit, with cutoff box for the big Hobart T-300 which draws 110 amps input, at 300 amps output to weld 1/4 Rod at single pass...and since the welder has a 60% duty cycle I can use a 100 amp circuit for a short term 110 amp draw.

Machine used?
Good job btw.

 

Put the root and hot in my first piece of pipe today.
Didn't turn out as bad as I was expecting, had a short section that burned through before I turned my machine down, and I had one spot that closed up because I didn't keep the keyhole open.
Still need to work penetrating at the tacks but the teacher was pretty happy with it considering its the first time I've welded on pipe.
