keep turning the regulator up until you can get a smooth weld without porosity or excessive splatter.
The easy test is weld with it off, then you know how it acts with no flow.
Pretty much what I ended up doing. Porosity and splatter are minimal now, think most anything left is due to technique at this point.Quote:

Likely will end up upgrading either way, but it'd be nice to avoid spending more money for the moment.
Need to get more cutting wheels for the grinder so I can cut down that square tubing and make the cart to move the car to clean the garage out and up and rearrange everything for more space. Likely going to ditch/disassemble the two rolling service carts I have now in favor of a large multidrawer rolling tool chest. Still need to finish off the stand I built for the tool cabinet, and to get/make a step stool for that area. Many projects to do to try to get ready before spring break.
I'm thinking the dyno was possibly incorrectly setup too. Apparently (I wasn't actually there unfortunately) the dyno was coming up with front/rear roller difference errors, I also now have 2 flat spots on each front tyre where they locked up on the rollers.Quote:

Since its that time of the year, working on some stuff (top secret and what not) and trying to get a good head on picture of the 2G headlights with the front bumper off.

Basically a shot about like this. Area that I'm looking into is where that pop up motor is on the 1Gs (the red dot to the side of that picture towards the core support.)
I'm sure you guys can guess what I'm doing, but haven't found a really good picture of that area at an angle like this yet. Wanting to get some stuff planned out before I cut out my old 1G buckets and weld in these 2Gs.
Practing welding is fun isn't it? I love it.

Those welds are looking too cold and you are definitely moving too fast. Try slowing down first. Also, what's your helmet darkness set at? USually around 11 works great. Looks like you missed the joint on a couple which could be due it being set too dark. For myself, a bit of oscillation helps me guide the puddle and make the weld my desired thickness. Also helps because I don't have to pull a perfectly straight line.
Once you get a new gauge and regulator, I would turn the cfh down to the mid 20's. 50 is far too high for these applications. (unless it's your gauge being stupid which sounds like it is.)
Good luck!
Oh yeah, I made some progress on my car as well. Determined exactly how i'm doing the transmission tunnel and made one of the braces that goes over it. No pictures though.
Gauge is definitely bring stupid, Eastwood emailed me this morning though, they're going to ship me a new regulator. Hopefully it works out.Quote:

Setting was at about 11-13, but the angle of the lighting has it coming around my head behind me so it makes seeing very difficult (part of why I need to rearrange everything out there.)
One of my coworkers used to be a welder, he said he would come by and give me some pointers soon so that should help. Going to watch more videos to get a better idea of what I'm looking for while welding.
Regulator issue is definitely something that has me on hold until it's resolved. Just not sure I trust welds on a cart to hold the car without knowing for sure I've got everything set up properly.

Played with it a bit more last night, think was the closest I got to a decent weld but regulator is probably still too low.
Pictures are overrated anyhow.Quote:

Up your wire size also to probably a 0.35 if you haven't already. Preheating the part with a torch will also help.
