Harper Trucks Series 700 Welding Cylinder Ha Unit EA. The drip tray and spout collect contaminated brown (from the gases evolved during welding) fumes for reuse. Clean out old exhaust with a steam tweezer or utility knife. Clean up afterward with running hose and scrapping carbon deposits from the cylinder and exhaust system. Debris and dirt from the work area such as from slag removal chippings and pipe mud is an absolute last chance for clean neat organized fumes. Harper's new AdvantechTM Welding Carts are the perfect match for our Series 700 Shop Fox Welders and perfectly match our Series 700 Heavy-Duty Cylinders and their replacement drain tubes. Harper's new patented Swirl-Off feature on the 700 models clears the blockage that can occur when using the Tweezers in reverse. There is also a built in magnet on the lower face of the welding tray that can catch slag and minimize or eliminate slag; this also prevents contamination of fumes from deposited material on the tray.
