I would like to start looking for a welder that may be used to make exothermic-quality welds. What features should I look for in a an affordable occasional use device, please? (i.e. not a commercial
All welders produce exothermic quality welds, in the hands of someone who knows what they are doing. The welding process produces an alloy of the base metal and the weld metal. There are three main t
So how well would brazing with a Bernzomatic or similar Propane or MAPP torch work for bonding copper ground wires to copper-clad steel ground rods? Alan AB2OS (who did manage to produce some service
It is difficult to weld metals of different melting points and conductivity and end up with a good weld quality. Hence it is usually done using an exothermic process instead of regular welding. If y
If you are talking ground rods, it's by far cheaper (and easier) to just purchase a few "one shot" cartidges. Everything comes premeasured. You just fit the form around the rod, put the ground wire i
just provided, I now have some where around 33. I lost track. <:-)) Purchasing them by the carton they are roughtly $10 each. There are 12 per carton and of course the price break comes at 13. IF th
Exothermic welding is unlike traditional welding where an electrical (Mig or Tig) arc is used. When it comes to welding copper conductors, a traditional weld or braze merely joins together the two su
and welding recall and I find that one reason aluminum is so hard to do good welds on is that it melts well below "red heat" color. With steel, the color of the metal tells you when it's about to me
TT: Check out www.therfc.com (The RF Connection) near here in Gaithursburg, MD. Their prices for one-shots are a bit better than ten bux a piece. 73 de Gene Smar AD3F (Not an employee, just a satisfi
Unfortunately for me the shipping would be a killer. There is this Hazmat thing about to contents. <:-)) Besides I have a full carton of the things out in the shop. I was paying about $8 plus change,
The manual method equivalent to the Cadwelds or other name brand exothermic "one shot" welds is brazing or braze welding. You can braze with Oxy-Acetylene and Mapp. The problem with the manual method
<<Also "to me" TIG welding is much more of an art than MIG, or stick welding and a class on welding would be a good idea.It usually takes most people quite a few hours before they can run a good hori
Personally I pay only about $6 each for my OneShots. I have to order a case at a time (12 ea.) and order from the local industrial supply house (I use Steiner Electric) with whom the plant has an acc
I'm not sure how they get around the Hazmat conditions. "One shots (TM)" come complete. There is no deactivation or activation. The material itself is considered hazadarous. It'd burn a hole in a con
Exothermic welding material is NOT a Hazmat material. Whoever is charging you hazmat handling is pulling a fast one on you. Always light the weld metal with a flint igniter. Using a match greatly inc
