The possible hazards are shown in the adjoining symbols or explained in the text. Wear safety glasses with side shields. Arc rays can burn eyes and skin wear a welding helmet with correct filter, and cover exposed skin with nonflammable clothing. NOTICE Indicates statements not related to personal injury. Indicates special instructions. eware of electric shock from welding electrode or wiring. Touching the electrode while in contact with the work or ground can cause electric shock. Always wear dry gloves. Keep all panels and covers closed. Welding sparks can cause fire or explosion. Move flammables away. Do not weld on closed tanks or barrels they can explode. Clean tanks or barrels properly. reathing welding fumes and gases can harm your health. Welding requires good ventilation. If ventilation is impossible, such as when welding in a confined space, use an air-supplied respirator. CALIFORNIA PROPOSITION 65 WARNINGS Welding or cutting equipment produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code Section et seq.) This product contains chemicals, including lead, known to the state of California to cause cancer, birth defects, or other reproductive harm. Wash hands after use. 2. Specifications and Location This unit is an interface control designed for use with a DIALARC HF welding power source. This interface control provides a connection point for a remote contactor and amperage control device (not supplied) such as an FTC-23, RFCS-23, or equivalent. The necessary interconnecting cords are supplied with this unit to connect it to the welding power source. This control is equipped with two 6 ft. (1.8 m) cords for making connections to the welding power source control circuitry. Lead lengths must be considered when locating the control. The control can be placed on top of the welding power source or at a nearby location. The service life and efficiency of the control are reduced when it is subjected to high levels of dust, dirt, moisture, corrosive vapors, and extreme heat. C A C 7-1/2 in. (191 mm) 9-1/2 in.

Connections Amperage Control Plug Route and connect 3-prong plug from control to welding power source Remote Amperage Receptacle. 2 Contactor Control Plug Route and connect 2-prong plug from control to welding power source Remote Contactor Receptacle. 3 Remote Control Receptacle The remote control device is not supplied with this unit. Obtain the desired control (an FTC-23, RFCS-23, or equivalent), and route and connect plug to this receptacle. See instructions supplied with the remote device for proper operation. Using the supplied adapter cord: Allows remote controls with 14-pin plugs to connect to the 5-pin remote receptacle on MIC-4. For proper operation of this control and the remote control device, rotate the Amperage Adjustment Control on the welding power source to the 100 (maximum) position. ST C 4. Routine Maintenance! Turn Off all power before maintaining. Disconnect unit from power source before repairing or replacing cords. 3 Months Cord(s) Replace Cracked Parts Replace Unreadable Labels 5. Troubleshooting Trouble Remedy No remote amperage control. Set switches and controls on welding power source to proper positions.* Check weld output on welding power source. Secure cord connections or replace cords, if necessary. No remote output (contactor) control. Remote Hand Control switch in wrong position, control not so equipped, or poor connections. Check switch settings, cord connections, and weld output on welding power source. Secure cord connections or replace cords, if necessary. *See welding power source Owner s Manual. OM-874 Page 2
