If it's bubbled and almost looks like a sponge, it could also be from too much gas flow or possibly, you have a breeze or draft in the area. If the cup you're using has say a 7/16" opening, your CFH rate should be about 12. Turning the gas too high also causes air turbulence at the mouth of the...

As for the acid... Not sure where people got the impression I was attempting to dilute it. Simply not the case. I was using it full strength. FWIW, the stuff available at Lowes (which is what I happen to have) is a 30% solution. As I recall during my college days, only higher mole fraction solution...

Raycj i bought a PM 25 unit and though its small its very accurate and works great for the small parts i need to fab. since retiring and relocating my shop space is considerably smaller so my tools need to fit my space. craig Those PM25's sold like hotcakes and I recall selling at least 5 or 10 to ...

The PM mill and other equipment in general is fine. The one seen in the background is about 10 years old and has seen countless hours of use while I ran my fabrication business before going into semi-retirement. Matt (from Precision Matthews) is a great guy. I'm a little biased though because, for a...

Might want to make sure the outer and inner lens shields on your helmet are clean. The polycarbonate scratches easily and gets permanently fogged-up pretty fast. I change mine quite frequently and the difference in visual quality between the old and new lens covers is significant. BTW: Don't get rip...

Finally, after a couple decades, I built a dedicated bench for welding. In the past, I used the floor or rigged a makeshift table from saw-horses. Now I know how caveman felt after inventing fire, round wheels and cooked meat. Anyhow, I covered the top with a piece of 11ga HR and found myself strugg...

Hey there Artie... Thanks for the nod.

I wrote-up a few words about the new Vulcan over in this thread: http://forum.weldingtipsandtricks.com/v ... 30&t=12222

Hi Folks... I picked-up a Harbor Freight Vulcan MIGMAX 215 a couple weeks ago. It's my first MIG machine and I'm new to MIG welding; however, I've been using a couple other welders for a few years. About 5 years ago, I bought an Everlast 205S multi-process machine and taught myself how to TIG weld. ...

Hi. I'm Ray C and I'm new to MIG but am pretty advanced at screwing-up stick and TIG welding. I talked myself into getting a MIG unit and went with the HF/Vulcan MIGMAX 215. It seems pretty nice but I have nothing to compare it to. I manually mapped-out the IPM speeds and usually use manual settings...
