SAFETY §1 SAFETY §1.1 Signal Explanation The above signals mean warning! Notice! Running parts and getting an electric shock or thermal parts will take damage for your body or others. The corresponding notices are as follows. It is quite a safe operation after taking several necessary protection measures. - Page 4 SAFETY semiautomatic welding gun are also electrically “hot”. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition.
- Page 5 SAFETY arc when welding or observing open arc welding. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays. Protect other nearby personnel with suitable, non-flammable screening and /or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
- Page 6 SAFETY an explosion even though they have been “cleaned”. Vent hollow castings or containers before heating, cutting or welding. They may explode. Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather gloves, heavy shirt, cuff less trousers, high shoes and a cap over your hair.

INSTALLATION AND ADJUSTMENT 3.2 Duty cycle & Over heat The letter “X” stands for duty cycle, which is defined as the proportion of the time that a machine can work continuously within a certain time (10 minutes). The rated duty cycle means the proportion of the time that a machine can work continuously within 10 minutes when it outputs the rated welding current. -

INSTALLATION AND ADJUSTMENT When the power supply voltage is over the safe work voltage, there are over voltage and under voltage protection inside the welder, the alarm light will on, at the same time, the current output will be cut off. If the power supply voltage continually goes beyond the safe work voltage range, it will shorten the welder life-span. -
