SAFETY PRECAUTIONS These safety precautions are for protection of safety and health. Failure to follow these guidelines may result in serious injury or death. Be careful to read and follow all cautions and warnings. Protect yourself and others. Welding and cutting processes produce high levels of ultraviolet (UV) radiation that can cause severe skin burn and damage.

SAFETY PRECAUTIONS WARNING! Persons with pacemakers should not weld, cut or be in the welding area until they consult with their physician. Some pacemakers are sensitive to EMF radiation and could severely malfunction while welding or while being in the vicinity of someone welding.

SAFETY PRECAUTIONS continued WARNING! Electrical shock can kill. Make sure all electrical equipment is properly grounded. Do not use frayed, cut or otherwise damaged cables and leads. Do not stand, lean or rest on ground clamp. Do not stand in water or damp areas while weld- ing or cutting.

Contact the manufacturer of the generator for this information. Everlast does not have an “approved” list of generators. But, if the generator is not listed as clean power by its manufacturer, then operation is prohibited. Generators that do not at least meet the operating input requirements of the welder are also forbidden to be used with the welders.
Section 3 Basic theory and function Welder Function Summary and Explanations. Most of the green coded controls on the welder panel are devoted to the use of the 2T/4T operation and 1. 2T/4T sequencer. The 2T/4T feature allows op- should not be used with foot pedal.

Section 3 Basic theory and function 4. Pulse. The pulse creates two amp values, a high EXAMPLE 1 and a low value that cycle back and forth between Welding Amps: 100 amps, each other while welding. The upper amperage is PulseAmps: 50% called the “welding amps”...

Amps through the ratio established by selecting the need a new one for your torch or damage yours, consult Everlast. Do not use a nipple that is scarred, bent or other- pulse Amp % on the panel. Welding with pulse and the foot pedal takes practice, as it will seem the welder is wise deformed.
Section 3 Basic theory and function TUNGSTEN PREPARATION 1. Use a dedicated grinding wheel or contamination may re- sult. Do not breath grinding dust! Wear eye protection and gloves. 2. Hold Tungsten firmly. 3. Grind perpendicular to grind- ing wheel face. Allow tungsten to grind away slowly, creating point.
Section 3 Basic theory and function LIFT START TIG OPERATION Note: A Lift TIG start should be done with a nearly seamless motion. Use a light touch and a quick motion for best results. FOR DC USE. NOT RECOMMENED FOR AC. <1/8”...
