how do the gasses make it to the tip of the gun ?

Current and gas both go through the lead (for the lack of a better word) that goes from welder to the gun. Then current is passed to the wire, while gas escapes around the wire, shielding it and the work piece from oxidation. Since the welder relies on the gas to stay in place a gas MIG does not work as well in windy environments, does not produce such high quality welds.

Edit: picture refused to show up, so there is a link instead.

Thanks, i edited, as it turns out the second video, does a good job at showing how that works, i still want to buy either but do like the quality TIG delivers. So since, there are some members who weld, i though " hey why not ask one of them to recommend a nice small cheap welder".

What's your budget? I have a few hook ups

Worked on my manifold this weekend. Just need to add another gate and it'll be ready to go.

for the love of god that looks amazing.

Almost ready for weld

I just hate when I tack it and it turns grey and mushy and dirty. I thought that was gas related but now I am confused to no end when it happens.

Here's some welds from a tool box side box I made earlier this week ......

And never mind my pics .
What do you do to prep the welds? They look super clean. I wire brush and acetone and still get black shit floating up top.

 

[Archer Fabrications]

^ has to be gas contamination of some sort, paul the reg i bought from you guys the adjustmebt screw o ring blows out consistantly and has to be re seated

 

[Gamble97]

How did you break it? Never have I seen anyone have that issue. Did you unscrew it all the way on accident?

 

[Archer Fabrications]

Well i had to unscrew it to re seat, i noticed seepage, i think i just need a new onring. The interesting thing is you should be able to unscrew it so you dont mess up the burden tube by puahing 2000 psi at it soon as the valve is on, but i think this reg is a little different, otherwise everything worjs

Email me pics at work.

That was just a really clean plate of aluminum. The Edges were very clean cause I had all the pieces cut using a sheer. I Scotch brighted the faces but not the edges.

Wastegate for a turbo 350z crossover pipe I just finished up earlier

A little aluminum tonight. Switched over to a pyrex kit. My gas tank is damn near empty the gauge doesn't even read , but I'm going to rip it until there isn't an oz of gas left.

 

[Gamble97]

New software = soooooo confusing

 

[familyMAN]

Reluctant to post after AllMotorMike but here are pics of WG dumps I added to my td05 kit when I still had the 6g in the car. The kit previously recirculated.

Got a question for some of you fabrication guys. I am rebuilding my boat trailer and i am replacing the beams that go from left to right that hold the support bunks that the boat sits on . I am removing a 16 2x3 gauge press bent piece that is probably bent 20 degrees. I am replacing them with 11 gauge 2x3 tubing. I don't have any way to bent the tubing, so i am going to cut them and butt weld them together to make about 35-40 degree v shape beam. They aren't going to have a ton of weight on them, the boat weighs 2500 lbs. There will be 4 of these beams supporting about 80 percent of that 2500 lbs, so about 2000 lbs. Looking at other boat trailers they are just welded together with no gussets or anything. My brain for some reason won't let me get away with just welding them together. I am trying to figure the best way to brace this. I can't just put a gusset iniside the angle because that will lead to clearance issues with the boat. One of my ideas is to cut a piece of flat plate that will fit over the side of the joint. After welding it together and grinding the bead down i planned on welding these plates to the side of the joint. My other idea was to take a piece of thicker plate and cut a strip that is as wide as the tube. Than i was going to bend it to the angle of my beam and weld it to the bottom of the beam. It would be kind of like a tension strap. Which of these 2 ideas seems like it would work the best, i am open to other opinions also. I made a quick drawing in paint. I drew both types of brace that i am talking about, one in red and one in blue.

Built an upper intercooler pipe using an old exhaust system i had laying in the basement. Not ideal i know, just did it for practice and to replace all those t-clamps and couplers in the background from the old pipe.

Haven't done much tubing or thin gauge before this. Needless to say, was just happy not to burn through or have to grind any welds out! Glad it didn't have to come down to that.

R1, Nice man it doesn't look bad. Great job on the pie cuts. The bends look very consistent and that's hard to do. Great test piece.

 

[Gamble97]

Man that looks good. I have to learn how to pie cut still.

Not a clue to be honest. Maybe try drawing up a pic so people can get a visual? or post on a welding forum where people may have had a similar job.

Appreciate the feedback guys, the pies themselves were easy just a LOT of work deburring, fitting up, and the funnest part of course welding it all up! I absolutely love being able to weld, even though i'm not a great welder, it feels good being able to build things like that. Just got another issue with my LICP, before i would've been sitting there and trying to figure out what to do about it. Now, i'm like no worries, i'll just cut this, weld that and should be good to go.


Bryanwheat, i agree with Gamble you would probably get a much better response if people could see exactly what you are trying to do. Hopefully, someone could help you out.

 

[Gamble97]

How do you guys cut out holes for flanges like bovs' and such? i used a large step bit and plasma cut the rest. Wasn't a great idea

Got this gem tonight though

I do have one posted, it is right below my post. It is not an externally hosted pic so you have to click on the link. At this point it doesn't matter to much. I found a real good deal on a trailer that is made just for my boat. Now i have to find somethign to make with the 8 3 foot pieces of 2x3 tubing that i bought. I with i wouldn't of cut it up yet, .
