My beads were pretty lumpy, but the steel was rusty, and the wind was blowing 10-15. I'm also left-handed which complicates teaching experience. But I did get good penetration. The rig I used was a hybred: hoses and regs were HF, torch was Lincoln. Which begs the question: is an HF torch worth the $100? Or should I keep saving my pennies? What size tanks would you recommend? I'm looking at .120" to 1/4" mild steel for a trailer, and from 1/2"x.030" to 2 -1/2"x.095" 4130 tube for a plane or other projects. Do you think the included tip sizes would handle that range? Can Lincoln or Harris tips be used on an HF torch body? Just wondering. Harry I've welded a Delta together with a HF torch, and everyone that I can get to inspect them (and I ask everyone) thinks they are just fine. Just keep the tip clean and you'll have no problem. Gas welding torches have been around for over 100yrs, and there really isn't that many ways to drill an orifice in a piece of copper/brass/whatever those things are made of. I wouldn't want to do extensive welding of 1/4" anything with a gas torch, though...unless maybe it was the dead of winter. A TIG or wirefed MIG are much more useful there. |
