These filler metals will either be electrodes, filler rods, or continuously fed wire depending on the welding process chosen. A third source of metal also known as filler is usually introduced and melted together with the two base metals to add to the total mass of the weld. The molten liquids then combine in the weld pool and will become one when the molten metals solidify. It consists of heating two pieces of metal to the point at which they melt. Always make sure your safety glasses are able to filter unwanted UV rays as well. Always wear safety glasses in conjunction with face shields for additional eye protection. Wearing safety glasses when tools are sending particles airborne is a must. The dark lenses will filter out much of the brightness allowing you to see what you are doing better. Welding and cutting goggles will protect your eyes from harmful UV rays. Always wear safety glasses under your face shield when grinding, buffing with a wire wheel or flap disc or cutting with a chop saw. Having multiple face shields nearby means you will be more apt to locate and therefore wear one when needed. Always Use Face ShieldsĪt least one is an absolute must to have in your welding area. It is time-consuming but the finished product will be worth the trouble. Do this until you have a complete weld all the way around. Keep moving around the piece making short welds and taking periodic breaks to allow some heat to dissipate before welding again. When welding larger sheets of steel such as a floor for a trailer, weld a short bead before moving to the opposite side of the sheet to do the same. A thin sheet of copper or aluminum on your tabletop will also keep the project from arcing between the table and the workpiece causing it to stick. If your projects are too small to clamp to, a small copper wire from the ground to the workpiece should do the trick. Grounding directly to your work is the most obvious remedy. 3. Keep your Project from Sticking to the Welding Table For that reason, do this only as a last result and with caution. The rod will become red hot in just a few seconds. This will cause the rod to heat up very quickly and the heat may help evaporate the moisture held in the flux. If you have no dry rods to finish your job with, try sticking the rod to the base metal for just a couple of seconds.

It is also handy to store anything else you may want to keep dry and dust free. This aids in keeping moisture away from electrodes.

Many welders will store their rods in an old discarded refrigerator. Discard electrodes if the flux becomes flakey and separates from the steel easily. To remedy this problem always store rods in a sealed container when not in use. If you have the correct polarity and are welding in the recommended amperage range for the rod you are using and your rod is not burning smooth and consistent, your rods may be damp. Damp rods may cause the arc to be rough and erratic. Rods that have soaked up moisture from the surrounding air will weld very poorly. Read my post, What is a Pancake Hood? for more information. Made popular by pipeline welders and other industrial welders who do a lot of welding outdoors, the pancake hood might be your favorite once you’ve tried one. If you have never used a pancake hood before, you should give one a try.
