Anything welding

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.

 

Finished up SMAW pipe for the semester today, moved onto TIG.
Root (6G), not perfect but good penetration and fairly consistent.


6G caps
Pretty happy with how they turned out because the caps is what I struggled the most with.

 

Need advice. Maybe some of you fellas can point me in the right direction. I have never messed with power inverters to step up/step down my volts. Im looking to purchase a quiter welding machine that plugs into 220 and get rid of my loud as bobcat 225. However i have no 220v outlets and my breaker box is old and cant add any new breakers. It would cost more to update all that so a friend told me about using an inverter. My question is whichone is a good one for my appplication? Any of you have experience with some?

 

I think you mean transformer. Inverters change AC to DC and vice versa

 

Update the panel. They are relatively cheap and easy to do if you have wiring skill. I don't know about your area but around me there are surplus electrical stores that tear out old buildings and sell panels with breakers and all that for real cheap.

 

Do you have an electric dryer or stove? Make an extension cord to reach the garage. Those appliances are 240 volts.

But seriously, think about updating the panel.

 

What is that jig in the last picture? Tubing Jig?

 

He might not even have 220 /240 even coming into the house.

This could turn into a major project

Pictures of your breaker box would be a great help.

The neighbors or Wife/ Girlfriend complain about the Bob Cat noise

Ear plugs I never weld without out them Quiets my Diesel TrailBlazer so I barely know it is running

 

I got 220 for my stove. Should i figure out what amps it allows so i dont buy a machine rated for more? I will make an extension cord coming from it.

 

Depends just how far it is from the stove outlet to where the welder is going to be used .

In your case a Sub panel might be a real good option over a extension cord

Remove the breaker for the stove replace it with one to power the sub panel run the stove and the welder from the sub panel . Run wire to where you need the welder outlet or outlets to be.

Any chance your going to be baking and welding at the same time ??

Just which welders are you looking at ??

 

Best answer yet. Put in a sub panel for a little money. Extension cords to run a welder can be pretty expensive.
