thanks for the tip

Yep, unfortunately I am dictated by my means. The shop I work for wont pay for a second regulator setup so I am stuck doing this. I have purged before but I had to run the 75/25 out of the MIG bottle to purge, it actually does pretty well. The color turns to like a golden haze on the inside. I usually only purge for anything pre-turbo, IE Subaru up pipes, manifold repair, ect.

+1 on the auto fab crap
most people in the industry cap out at making under $20/hr
at least around this part of the country

Here is my cage I just constructed over the past 2 months. I really do not know how to count the points, but I guess it is a multi point. Hand made, not based on any modified kits etc.

DOM 1.75" tubing. MIG/TIG welded.

Bolt in cages are not safe.

In a weld in cage 1/8" is fine if you have sufficient coverage.

1/4" for land speed cars.

So you say in the auto fab industry the cap is low like that?? i guess the only way to get in the money there is to start my own r&d shop then

The bend is to follow the shape of the roof like it suggests in the NASA rule book. It also gives you much more visibility and in a roll over it will keep the cage from crushing in on you.

thanks,
that was based on my buddy who built cages for someone...he had like 10 years exp...he works for the Sheriff now hahah

the guy I replaced started his own business
shit I'll give him a plug Mo-Fab
pretty sure he capped out about that...he had been working for that business for 7 years, and been fabbing for longer than that

that is probably the way I will go in a couple of years, I have only been in the biz for 2 years now

Just picked up some new welders for the shop.



Miller Dynasty 200DX Tig

and

Miller Millermatic 212 auto set.


The first time I used a 200dx was when Jonnie Fraz came down to my shop. He had just purchased it. The first weld I ever laid down with it turned out to be the best I had ever done. The arc shaping and control are superior to any machine I have used. I look forward to showing everyone what we create with these exceptional machines.

TheBlackNasty: We got a good deal on the pair.


I actually played around with the arc balance and wave shaping tonight. I have to say I am impressed with the cleaning ability of the machine.

I will post up some pictures tomorrow.

So jealous of that Dynasty setup. Perhaps someday, but I'm not sure it makes sense for a "hobbyist".
