Title: My First Ramhorn
Post by: malichite on March 16, 2009, 01:20:30 AM: Been working on this for a while on and off but just finishing it up today. This is the first ramhorn I have ever made.

Post by: malichite on March 16, 2009, 11:40:11 PM: nope, just set it and forget it. no hf start either. Scratch start for the real :somb:

Harbor Freight Tig

How did you get the hang of scratch start? Even using a copper block, it sticks half the time. That's even using the homemade pedal I rigged up. :-[
Title: Re: My First Ramhorn
Post by: onlyflash944 on March 18, 2009, 11:26:08 PM: nice compressor

decent mani, espically with the hf tig

Start by pounding a beer. <---This is necessary for me because I get the shakes a lot (to much caffine)

Next, practice practice practice. Remember, keep the tungston fresh and sharp. It is really hard to keep contaminents off the tungston because of the scratch start, but the better you can do the easier it is to start. If it sticks even once, stop, regrind and start again. I also got a gas lense and a real cup. The HF cups are really tiny. Switching to a gas lense you can run the standard size cup helps a ton.

these welds look excellent for a 200 dollar tig :yes:
makes me want to pick one up.. what was the total investment to get it up and running
Title: Re: My First Ramhorn
Post by: malichite on March 19, 2009, 01:01:37 PM: $200 for the tig, about 15-20 bucks for the gas lense and bigger cups, 80 for a good regulator and I had a bottle already.
Title: Re: My First Ramhorn
Post by: michigan_soler on March 19, 2009, 02:51:42 PM: did anyone do a pedal attachment for the HF tig?
Title: Re: My First Ramhorn
Post by: malichite on March 19, 2009, 02:59:31 PM: I've seen a couple posts where people have done it. Thought about it myself but been to lazy
Title: Re: My First Ramhorn
Post by: walter on March 19, 2009, 03:36:05 PM: what cup/gas lense did u use?
Title: Re: My First Ramhorn
Post by: malichite on March 19, 2009, 04:39:40 PM: Not sure. I went to PacWelding and said i want a gas lense. I am running a #5 cup right now. It is a little small. thinking of going up a size.
Title: Re: My First Ramhorn
Post by: walter on March 19, 2009, 08:50:22 PM: i got this kit and looks OK to me..

Post by: walter on March 19, 2009, 09:43:39 PM: what the hell is a gas lense ? i tried to figured it you what really it's in spanish but i dont get it what that means :somb:

can u post some pics about what is gas lens buddyÂ¿
Title: Re: My First Ramhorn
Post by: walter on March 19, 2009, 09:53:18 PM: i assume this is gas lens..

didnt know it's needed this for weld with TIG
Title: Re: My First Ramhorn

Title: Re: My First Ramhorn
Post by: walter on March 19, 2009, 10:01:21 PM: ok, ill get one then!

what do you cup# use?
Title: Re: My First Ramhorn
Post by: dvst8r on March 19, 2009, 11:28:10 PM: I use #8 with the Lens unless it is really tight then I have a #6, and a #5. 95% of the time it is a number 8, as with the lens if I need to I can get over 5/8" of tungsten stick out without an issue. This allows me to get into most everywhere with a #8.

you run the gas lense on the HF torch, or did you use a different torch as well
Title: Re: My First Ramhorn
Post by: malichite on March 20, 2009, 04:00:41 PM: I run it on the HF torch

Post by: malichite on April 17, 2009, 11:19:27 PM: Still going at this slowly. Got the downpipe done and wastegate added plus dump tube. Just have to do some finish welding and it is ready to go :yes: Madussa anybody?

Post by: Toysrme on April 18, 2009, 12:05:35 AM: you're boarderline burning it up.
this will sound counter-intuitive, but here you go! - your heat input is fine and could stand to be a little hotter. you're just welding too slowly and the average heat input is becoming way too high as the material heats up.
whatd you use on the strut tower bar? get you some ER80S-2 or ER80S-6.
watch where you are scratching your tungsten. You should scratch inside the weld area prefferably closest to the root as you can.
when you want to stop welding, toss your filler (clip the last inch off before using the rod again) and back off your heat input while you slowly pull your arc away until it goes out. you're probably close to getting star & crater cracking.
remember 10 seconds post flow per 100amps.

pretty good first effort
