Today was one of those days when you wanted to get a lot more done than you actually did.. Don't get me wrong; we made some progress, but the elements didn't help (if only we lived in Jamaica!).. Anyways, I didn't want to leave you guys with absolutely NOTHING, so I took a few pics of what little we did get done.

We cut the tongue down to size...it was just way too long. We took approximately 3ft off so the overall length is at about 18ft now.

De-greased the frame and hit it with some POR15...The wind was ferocious so we paused on that temporarily.

Got the inner box welded on all sides. The end that will be attached to the cooking chamber is face-down on the ground. As you can see, there isn't a 2in gap there like the rest of the box...saved about 40ish dollars and that side of the box honestly doesn't need to be double insulated. We'll add a small section of angle iron at the corners (on the sides) for extra support and to keep the walls spread so we can fit the other piece on with ease :-D.

This is another shot of the firebox just so you can get a feel for its over all size. If we wanted to, we could actually ball ourselves up inside (not at the same time of course).

This is a shot for those who are concerned about the stability of the project :boxing:...just a sample of the weld..the good seams were on the bottom, but the arc welder is providing excellent penetration. The breaker switch would flip every 3-4 inches so there was a lot of stoppin' and goin'.

Last weekend didn't leave much to share, so I thought I'd add a few bits from today to hold you over until this weekend. While I was home, the old mane took to the firebox some more.

This is just a shot of the firebox where the door will be...pretty obvious, I know...

This is a shot of the firebox - chamber opening.. you can kinda guess where we got the plans for the build :-D . The flap isn't bent out enough yet..we'll have to heat it up to get it down another 15 degrees or so..

The last shot is the aftermath of my dad catchin' his self on fire while cutting the openings..

If you're tripping a breaker that often...some thing is very wrong!

Nice build though...looking forward to seeing the finished product!!!

Haha! You're right! The outlet is wired with like 14-16ga wire. The small wire is just heating up too fast :tsk: . It gets annoying for sure!
 
Are you purposely trying to start an electrical fire? What size breaker is feeding your welder outlet? A 20 Amp breaker and outlet should be running 12 ga wire...and 20 Amp may be a little light for the welder you're running?
 
Preachin to the choir here. Unfortunately, it is what it is and you gotta work with what ya got... The breaker is there to break, though and it's definitely doing it's job.. There won't be any fires, just a lot of starting and stopping. We might rewire the outlet since there's a lot of welding left to do.
 
Maybe drop yourself a better circuit out of the panel if its available, even if its just temporary. We just got done wiring a remodel that was spurred by a fire caused by an overloaded circuit. Are you plugging into a drop cord? If so go straight to the outlet. My 120V welder works fine on a 20 amp circuit but will trip if I'm welding 1/4" material (hot) continuously. Good luck, it's looking awesome!
 
The circuit breaker is there to keep the panel from getting over loaded. It's not going to keep the outlet from getting over loaded...which is a likely place for a fire to start, or some where in the wiring between the outlet and breaker due to to much resistance. It takes about 10 minutes to wire in a new dedicated circuit and outlet.
 
We will probably rewire with 12ga. Right now it's wired with 14. We are welding 1/4" steel which is adding to the dilemma. We're just using what we have. We do have some 12ga wire so we'll probably be making the upgrade this weekend. Wont be able to do much beyond that without spending more time and money. No fires yet and we've welded several feet. With thicker wire we should do a bit better.

Not exactly. The circuit breaker is there to protect the wire.
In theory it will trip before a wire gets hot enough to melt and short circuit.

NEC requires a 12 awg wire to be protected at 20A and a 14 awg wire to be protected at 15A.

14 awg wire will run 20 amps fine, but will get warm.

It is voltage drop that will get ya.

Running a welder on 14 awg wire over a long distance will lower the voltage (due to the resistance), which increases the current draw (amps) of the welder.
I imagine if you were to put a voltmeter on the circuit in question while you welding, you would probably see a significant voltage drop (10-15 volts) from the panel to the welder. So even if you are leaving panel at 120V, you may only be seeing 105 volts at the welder.

Which of course raises the amps the welder is pulling, and tripping the breaker.

Either way...I would look at how many Amps the welder is rated to draw and make sure that the outlet it was plugged into had a dedicated breaker rated for those Amps. And I don't think I would run less than a 20 Amp breaker for a buzz box welder. But that may be just me being paranoid from seeing what the out come can be because of running a lower amp breaker and outlet.

It causes concern to hear that a breaker is tripping often when welding is occuring and nothing is changing to keep it from hapenning. It's telling you that some thing in the electrical system can't handle what you're doing and things can get real ugly real fast if some thing doesn't change. I'd had to see some one get hurt when it's avoidable is all.
 
Just to set everyone's mind at ease, we are aware of the complications and the outlet is only 1.5ft away from the garage door opening...There is also a big red fire extinguisher sitting right by us at all times. Anything we could/would need to choke an electrical fire is within arms reach. We know what the optimal setup is and what we are currently using. The breaker can trip 100 times in a day and you probably won't see one fire..or a spark.. The wire cools within 30-60 seconds, then its back to business.

The only thing that will get hurt is a back from bending over much longer than is normally required...or somebody catching on fire from sparks while cutting/grinding steel :-D. Honestly, an electrical fire is a much smaller concern than worrying about increasing our weld time 10 fold.

Aside from safety concerns, we are happy with our current progress. Things are taking shape and moving right along. So far there's only been 4 days of actual work put into this build. Hopefully we can finish in another 4-6 full days.
 
Looking forward to seeing it completed. Are you making it walk up from the ground, or are you going to step up onto the trailer?

Are you referring to how we will load the fb onto the trailer? If so, we'll have about 4 guys lift it and set it on the tail end of the trailer.

I think he was asking if you were planning it so that you could cook/operate it from standing on the ground or if you were going to be standing on the trailer to cook. That's what I got from it anyway.

Project is looking great so far. Wish I could find enough time to knock a good chunk out of mine, but its been slowgoing on my build due to time constraints and such.
