SAFETY PRECAUTIONS HEALTH HAZARDS: Welding produces intense electric and magnetic emissions that may interfere with the proper functioning of cardiac pacemakers, hearing aids, or other electronic health equipment. If you use such devices, you should consult your medical health professional and the manufacturer of the health device before using the welder. GASES AND FUMES: Gases and fumes produced during welding can be dangerous and hazardous to your health.

Replace or repair all worn or damaged parts. Disconnect the power source before performing any service or repairs. Read and follow all the instructions in this Operator’s Manual. FIRE AND EXPLOSION: Fire and explosion can be caused by hot slag, sparks, or the welding arc. ...
COMPONENTS/ACCESSORIES Below is a list of the components of the 160 DualArc stick welder by Work cable/clamp (to be connected to weld piece). Electrode cable/holder (holds welding electrode). Input power cable (comes without plug). Rotating Amperage control knob. Power selector switch (to choose between OFF, 110V and 220V input). Power indicator light (green - lights when machine is connected to electricity).
ASSEMBLY AND INSTALLATION Carefully unpack the product and verify that all the parts and accessories identified earlier are present in the machine and do not appear to have been broken during transportation. If a missing or defective part is found, please contact your retailer to obtain a replacement. The 160 DualArc welding machine comes without a power plug.
OPERATION You must identify whether your input power circuit is 110V or 220V (+/- 10%). This will determine whether you will choose to weld in the 110V or 220V mode. Selecting the wrong welding voltage will result in damage to the welding machine. If you are not certain of the voltage provided by the circuit, do not operate the welder, and seek assistant from a qualified electrician. All metals that are welded must be properly cleaned of any rust, moisture, grease, plastic or other non-metal external agents before welding.
ARC WELDING BASICS Arc welding is a process in which metals are joined together using heat developed by a welder. Current passes through the metals via the work clamp and the electrode (and the electrode holder), thus forming intense heat which results in a weld. The incandescent space between the weld area and the burning electrode is commonly referred to as the arc. This unit is an AC (alternating current) welder, which means that current travels in both directions of the welding circuit, in quick alternations (50 or 60 times per second, for 50Hz and 60Hz frequencies).

Starting: Initiating the arc may be challenging, especially to the novice welder. It is recommended that users practice and familiarize themselves with the machine by welding some scrap metals before starting a job. An arc can be initiated by either scratching or tapping the electrode onto the weld metals. After the arc is started, it is important to swiftly leave a slight gap, or the electrode will weld itself onto the metal. However, the gap must not be too large;...

Arc speed: Because the electrode is melted continuously into the weld, it is important to continue feeding the electrode accordingly. However, this must be done at the right speed. When the travel speed is too fast, the resulting bead is narrow and penetration is poor. When the speed is too slow, the bead is high and wide and the metal tends to overheat. Overheat protection: The unit will automatically shut down once the duty cycle is reached.
BASIC CARE Always unplug the welder when it is not being used. Worn parts or damaged parts (cables, switches, plugs, handle) should be replaced promptly (see Parts List). When the welder is used outdoors, it should be kept from rain or long exposure to the sun. Inspect the welding cables from time to time to ensure that they are in good condition.

Unit overheats prematurely. An extension cord is being used. Relocate the welder or use a thicker extension cord. Electrode being used is too thick. Use smaller diameter electrode. It is difficult to start the arc. Electrode diameter is too large for the Amperage Reduce electrode size or increase Amperage.
