3.The 208/230 volt 50/60 Hz model POWER MIG is shipped with a 7 ft. input cable and plug connected to the welder.

4.Using the instructions in Figure A.3, have a quali- fied electrician connect a receptacle (Customer Supplied) or cable to the input power lines and the system ground per the U.S. National Electrical Code and any applicable local codes. See “Technical Specifications” at the beginning of this chapter for proper wire sizes. For long runs over 100 feet, larger copper wires should be used. Fuse the two hot lines with super lag type fuses as shown in the following diagram. The center contact in the receptacle is for the grounding connection. A green wire in the input cable connects this contact to the frame of the welder. This ensures proper grounding of the welder frame when the welder plug is inserted into a grounded receptacle.

OUTPUT POLARITY CONNECTIONS

The welder, as shipped from the factory, is connected for electrode positive (+) polarity. This is the normal polarity for GMA welding.

If negative (–) polarity is required, interchange the connection of the two cables located in the wire drive compartment near the front panel. The electrode cable, which is attached to the wire drive, is to be con- nected to the negative (–) labeled terminal and the work lead, which is attached to the work clamp, is to be connected to the positive (+) labeled terminal.

IM693 specifications

Lincoln Electric IM693 is a cutting-edge multiprocess welding machine designed to cater to the needs of both industrial and commercial applications. Renowned for its versatility, this machine can perform MIG, TIG, and stick welding, making it an ideal choice for fabricators and manufacturers looking for a single solution for varied welding processes.

One of the standout features of the IM693 is its advanced inverter technology. This technology significantly enhances the efficiency of the welding process by reducing energy consumption while maximizing output. The inverter design allows for a more compact and lightweight unit compared to traditional transformers, making it easier to transport and maneuver in work environments.

The machine’s user-friendly interface is another compelling characteristic. It is equipped with a large, intuitive digital display that allows operators to quickly adjust settings for specific applications. The system is designed to provide real-time feedback on welding parameters, ensuring consistent and high-quality welds. This feature is particularly beneficial for both novice and experienced welders, facilitating a smoother workflow.

Additionally, Lincoln Electric IM693 incorporates advanced arc control technologies such as Soft Start and Auto Set features. Soft Start allows for a gradual ramp-up of the welding current, which minimizes spatter and leads to cleaner welds. The Auto Set feature intelligently adjusts the welder's settings based on the material type and thickness, taking the guesswork out of the welding process and improving overall efficiency.

The IM693 supports a wide range of input voltages, allowing for operation in various regions without the need for additional equipment. This flexibility makes it suitable for numerous applications, ranging from automotive repair to heavy machinery fabrication.

Safety is paramount in industrial settings, and the Lincoln Electric IM693 does not compromise on this front. It is equipped with several safety features such as thermal overload protection, which prevents machine damage from overheating, and a sturdy casing that protects vital components from dust and debris.

In summary, Lincoln Electric IM693 is a robust, versatile, and technologically advanced welding machine that meets the demands of modern welding applications. Its combination of inverter technology, user-friendly features, and safety measures makes it an excellent choice for professionals looking to achieve high-quality results with maximum efficiency.
