SAFETY PRECAUTION
WARNING
ELECTRIC SHOCK can kill.
•Only a qualified electrician should connect the MAXsa™ 10 CON- TROLLER. 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 electrically 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 electrodes 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 welding 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 MAXsa™ 10 CONTROLLER will operate in harsh environments and can be used outdoors with an IP 23 rating. Even so, it is important that simple preventative measures are followed in order to assure long life and reliable operation. The MAXsa™ 10 CONTROLLER must be mounted in the vertical(upright) position and located where there is little risk of impacts to the Controller.
HIGH FREQUENCY PROTECTION
Locate the MAXsa™ 10 CONTROLLER away from radio controlled machinery. The normal operation of the MAXsa™ 10 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 CONNECTION
The MAXsa™ 10 CONTROLLER has the ability to control auxiliary equipment such as feeders, flux hoppers and travel motors using solid state relays. There are three relays (CR1,CR2 &CR3) in the MAXsa™ 10 CON- TROLLER, 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.
MAXsa™ 10 CONTROLLER Relay Ratings: Coil: 12Vdc, resistance = 86 ohms at 25° C Normally Closed (N.C.) Contacts: 3A @ 277VAC Normally Open (N.O.) Contacts: 30A @ 277VAC
The MAXsa™ 10 CONTROLLER does not provide the input power to feed any equipment, other than the MAXsa 22 or the MAXsa 29 feeders. Therefore a separate power feed must be provided by the end user. The MAXsa™ 10 CONTROLLER has been shipped standard with all of the wiring and connectivity to operate the Lincoln K325
If either of these is to be used with the MAXsa™ 10 CON- TROLLER, the
WARNING
Although input power to MAXsa™ 10 CONTROLLER is turned off, the customer installed auxiliary input may be energized! Ensure that all input power to the MAXsa™ 10 CONTROLLER is turned off before open- ing the cover
