SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Have an electrician install and service this equipment.

•Turn the input power off at the fuse box before working on equipment

•Do not touch electrically hot parts.

GENERAL MAINTENANCE

In extremely dusty locations, dirt may clog the air pas- sages causing the welder to run hot. Blow dirt out of the welder with low-pressure air at regular intervals to eliminate excessive dirt and dust build-up on internal parts.

The fan motors have sealed ball bearings which require no service.

DRIVE ROLLS AND GUIDE PLATES

After every coil of wire, inspect the wire drive mecha- nism. Clean it as necessary by blowing with low pres- sure compressed air. Do not use solvents for cleaning the idle roll because it may wash the lubricant out of the bearing. All drive rolls are stamped with the wire sizes they will feed. If a wire size other than that stamped on the roll is used, the drive roll must be changed.

For instructions on replacing or changing drive roll, see “Wire Drive Rolls” in Operation section.

CONTACT TIP AND GAS NOZZLE INSTALLATION

1.Choose the correct size contact tip for the elec- trode being used (wire size is stenciled on the side of the contact tip) and screw it snugly into the gas diffuser.

2.Screw the appropriate fixed gas nozzle fully onto the diffuser. Either the standard .50" (12.7 mm) flush nozzle or other optional flush or recessed (spray arc) nozzle sizes may be used. (See Table D.2 in this section.)

3.If using optional adjustable slip-on nozzles, see Table D.2 in this section.

•Be sure the nozzle insulator is fully screwed onto the gun tube and does not block the gas holes in the diffuser.

•Slip the appropriate gas nozzle onto the nozzle insulator. Either a standard .50" (12.7 mm) or optional .62" (15.9 mm) I.D. slip-on gas nozzle may be used and should be selected based on the welding application.

*Adjust the gas nozzle as appropriate for the GMAW process to be used. Typically, the con- tact tip end should be flush to .12" (3.2 mm) extended for the short-circuiting transfer process and .12" (3.2 mm) recessed for spray transfer.

GUN TUBES AND NOZZLES

1.Replace worn contact tips as required.

2.Remove spatter from inside of gas nozzle and from tip after each 10 minutes of arc time or as required.

GUN CABLE CLEANING

To help prevent feeding problems, clean cable liner after using approximately 300 pounds (136 kg) of electrode. Remove the cable from the wire feeder and lay it out straight on the floor. Remove the con- tact tip from the gun. Using an air hose and only par- tial pressure, gently blow out the cable liner from the gas diffuser end.

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.
