FUME HAZARDS 1.5 WARNING: FUMES, GASES, AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS, AND DEATH! To reduce risk of discomfort, illness, or death, read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this welding equipment or is a bystander in the welding area, understands and follows these safety instructions as well. Do not weld in an area until it is checked for adequate ventilation as • described in ANSI standard #Z49.1. If ventilation is not adequate to exchange all fumes and gasses generated during the welding process with fresh air, do not weld unless you (the welder) and all bystanders are wearing air-supplied respirators. Do not heat metals coated with, or that contain, materials that produce • toxic fumes (such as galvanized steel), unless the coating is removed. Make certain the area is well ventilated, and the operator and all bystanders are wearing air-supplied respirators. Do not weld, cut, or heat lead, zinc, cadmium, mercury, beryllium, or • similar metals without seeking professional advice and inspection of the ventilation of the welding area. These metals produce EXTREMELY TOXIC fumes that can cause discomfort, illness, and death. Do not weld or cut in areas that are near chlorinated solvents. • Vapors from chlorinated hydrocarbons, such as trichloroethylene and perchloroethylene, can be decomposed by the heat of an electric arc or its ultraviolet radiation. These actions can cause PHOSGENE, a HIGHLY TOXIC gas to form, along with other lung and eye-irritating gases. Do not weld or cut where these solvent vapors can be drawn into the work area or where the ultraviolet radiation can penetrate to areas containing even very small amounts of these vapors. Do not weld in a confined area unless it is being ventilated and the • operator (and anyone else in the area) is wearing an air-supplied respirator. Stop welding immediately if you develop momentary eye, nose, or • throat irritation as this indicates inadequate ventilation. Stop work and take necessary steps to improve ventilation in the welding area. Do not resume welding if physical discomfort persists.

DESCRIPTION 2.1 Your new welder is designed for general repair, maintenance, and metal fabrication. The welder consists of a single-phase power transformer, and control switch. This welder is capable of welding with 1/16”, 5/64”, and 3/32” general purpose mild steel electrodes. Now you can weld 18-gauge steel sheet metal up to 1/8” with a single pass. Welds thicker metal with beveling and multiple passes. WELDER PERFORMANCE 2.2 Your welder has been designed to weld on steel from approximately 18 gauge up to 1/8” thick. Thinner and thicker material can be welded depending on the experience and technique of the welder and the type of welding rod being used. SPECIFICATIONS 2.3 Input Voltage 120 volt 60 Hz.
