LtBadd, Yes, it is a closed group meaning the posts cannot be seen unless you are added and are a member. I thought about that when I posted the link. I am not sure how many here are members on the Facebook group. I can however, get the three winners welds put up here sometime this weekend for all t...

Yes, there was some talent shown there!

Just so everyone knows, and to close out this thread, this giveaway has ended. There will be more down the road though so keep a sharp eye out.

jroark, I would recommend the spool gun as I have no experience with brazing alum. It will be difficult to get set just right and I recommend pre-heat depending on how big the actual piece is. Also, clean, clean, clean. I do quite a lot of cast alum repairs but always use TIG and 4043 works best as ...

kripl88,
The calculator I cannot share, propitiatory, but there are apps you can download that will get you close. Keep us posted on this project, this one peeks my interest.
-Jonathan

jroark, I'm not sure where I want to start with this one. I guess the first thing I should say is follow what your employer says above all else, unless it is a safety hazard of course. Those settings are extremely high for the given materials but I guess can work. Your wire speed suggests you are us...

I replaced the drive roller(with key) and push roller, both are knurled . the are stamped .035 WWoW, Here is the first thing that popped out to me but has nothing to do with blowing through your material. You should not use knurled drive rolls on alum wire. You will tear up the wire causing pieces ...

According to AWS D1.1 Structural Steel Welding Code, a 1G, 1" thick test plate will qualify you for 1/8" to unlimited groove and unlimited fillets as well as 24" O.D. pipe groove and unlimited fillet.

AndersK, I really like that design you have there. You need to post some of those pics on Instagram. Thanks for the mention as well. It is amazing how well the air mufflers do, and they are cheap. I paid full retail for one of mine at almost $10 but when you consider how expensive purge equipment is...

kripl88, You didn't mention the process but since this is the MIG section that is what I will assume. I have a calculator for mechanized MIG welders and it came up with roughly 20 arc hours using welding over 227" circumferential inches .045 Lincoln 81M (dual shield), 60* included bevels, using...

Members, Just wanted to let everyone here know that there is a TIG Finger giveaway on the Facebook page. Rules are simple, post up your best TIG (GTAW) weld and the post with the most likes wins the TIG Finger! Get over there and enter!! Contest ends 7/18/2015 at 12 noon. https://www.facebook.com/gr...

Laughablefusion, I can agree with everyone on both the "welcome, no question is a dumb one" and the answers to your question. To directly answer the walking the cup with mig, I do not recommend that, especially as a beginner. It is hard to do and you have to have everything set up right an...

Millerismyname, Here is another thing you can try that CrummyWelding (Roy Crumrine) showed me. He uses a #5 regular cup to cut down his etching zone. I use a gas lens and thought it is better but in testing, because I didn't believe him ;) ) I ran a gas lens and regular set up side by side and the r...

BigWill, I will let the article explain better the processes but yes, you are in spray transfer mode, and you are running pretty hot, around 300 amps I would guess. Keep in mind you need to do what your employer tells you but I advise against whipping motions when spraying, or any process really. Wh...

Richard,
Welcome to the forum. How about introducing yourself and letting us know what your end use is for the machine? Each of these have their good and bad points and might not suit your need.
-Jonathan

Matt, I have not used the Forney machines but have heard good things about them as a VERY light hobbiest. I would respectfully disagree with them being better than Miller or Lincoln machines but different strokes for different folks. I saw their booth at FABTECH 2014 and really didn't give them much...

John, Welcome to the forum! I am a little confused by your post, lets see if we can get a clearer image here. First, as was mentioned, a picture is worth 1,000 words so that would be the best help. Second, it seems like you are welding on used fuel tanks which brings to mind that you might be gettin...

Nick,
We are so close to each other, lol. I need to head to your shop one day and check you out and put a face to the screen name. I would be tempted but I do have a good job and am working on some induaturial furniture myself.
-Jonathan

Jody,
Great video by you two! I don't know if you noticed but Roy started a new profile under CrummyWelding a few weeks ago. I am trying to get him to post a little more as well (hint, hint Roy)
-Jonathan

HFT,
Thank you for that. I look forward to the discussion as I get into purging different items and want to get into the purge chamber market as well.
-Jonathan

huntingdon_fusion, Welcome to the forum. I appreciate the informative copy and paste article and I know you can add to purging conversations but as was already mentioned we do not allow members here to solely promote their products. I encourage you to participate in discussions in your area of exper...

The best thing I can advise is just experiment. That is what I have been doing lately for my quick videos.
-Jonathan

Roy,
Welcome my friend!! I can't wait to see your contributions here. Much knowledge learn we can from you. Now post up some of your awesome welds we can drool over.
-Jonathan

PBnKjelly, Welcome to the forum! The best of luck on your new venture. One thing I will add is I believe it is a DOT law, meaning across the country, that you cannot have your regulators hooked up while the vehicle is in motion. You must take them off and put the caps on. They do sell a cap that all...

Thanks for the kind words Jody! Video turned out great. Roy, It is good to see you back here! For those who don't know, Roy's business is Crummy Welding, hence the name, and I think he is retiring rediron881. I hope you can share some of your knowledge with us here. We look forward to your posts. -...

ogfrmpa, Welcome to the forum! The first thing to pop into my mind reading your post was, why are you lubing your wire? Generally, you do not need to lube wire, especially flux cored wire but maybe there is something I don't know. As for the wire feeding issue, are you sure it is something wrong wit...
