SAFETY PRECAUTION
WARNING
ELECTRIC SHOCK can kill.
•Only a qualified electrician should connect the POWER FEED™ 10A CONTROLLER. Installation should be made in accordance with the appropriate National Electrical Code, the local codes and the infor- mation in this manual.
•Turn off the input power to the power source at the disconnect switch or fuse box before working on this equipment. Turn off the input power to any other equipment connected to the welding system at the disconnect switch or fuse box before working on this equipment.
•Do not touch electrically hot parts.
WELDING VOLTAGE
Wire feed parts are electrically live while welding and while inching wire (with Touch Sense feature selection). The elec- trically live parts are listed below:
Electrode | Electrode Reel |
Wire Drive Motor | Drive Rolls |
Gear Box | |
Wire Straightener | Welding Nozzle |
Welding Cables | Welding Cable Terminal |
| CAUTION |
• Do not touch electrically live parts or elec- trodes with your skin or wet clothing.
•Insulate yourself from the work and ground.
•Always wear dry insulating gloves.
MECHANICAL HAZARDS
• Welding fixture or wire feeder will move during weld- ing or inching. Keep away from pinch points.
• Electrode reel and drive rolls turn during welding or inching. Keep gloved hands away from areas that may catch the glove.
LOCATION AND MOUNTING
The POWER FEED™ 10A CONTROLLER will operate in harsh environments. Even so, it is important that simple pre- ventative measures are followed in order to assure long life and reliable operation. The POWER FEED™ 10A CON- TROLLER must be located where there is little risk of impacts to the Controller.
HIGH FREQUENCY PROTECTION
Locate the POWER FEED™ 10A CONTROLLER away from radio controlled machinery. The normal operation of the POWER FEED™ 10A CONTROLLER may adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.
AUXILIARY EQUIPMENT INPUT POWER CON- NECTION
The POWER FEED™ 10A CONTROLLER has the ability to control auxiliary equipment such as flux hoppers and travel motors using solid state relays. There are three relays in the POWER FEED™ 10A CONTROLLER, controlled by two independent coil drivers. The coils of CR1 and CR2 are in parallel, therefore, they must turn ON and OFF at the same time. The CR1 and CR2 relays are designated for driving travel motors to control motion. CR3 is driven separately, and is designated to control flux hopper operation.
POWER FEED™ 10A CONTROLLER Relay Ratings: Coil: 12Vdc, resistance = 86 ohms at 25° C
N.C. Contacts: 3A @ 277Vac
N.O. Contacts: 30A @ 277Vac
The POWER FEED™ 10A CONTROLLER does not provide the input power to feed auxiliary equipment, therefore a sep- arate power feed must be provided by the end user. The POWER FEED™ 10A CONTROLLER has been shipped standard with all of the wiring and connectivity to connect to the Lincoln K325
If either of these is to be used with the POWER FEED™ 10A CONTROLLER, the
WARNING
Although input power to POWER FEED™ 10A CON- TROLLER is turned off, the customer installed auxiliary input may be energized! Ensure that all input power to the POWER FEED™ 10A CONTROLLER is turned off before opening the cover.
