MAKING A WELD

1)Use only a network compatible power source.

2)Properly connect the electrode and work leads for the correct electrode polarity.

3)Set all desired parameters such as trigger logic, Run-in Speed, Acceleration, Electrode polarity, etc. per “DIP SWITCH SETUP” in the INSTALLATION section.

4)Set 2-step, 4-step switch on wire drive to desired mode of operation. (Refer to “2-step/4-step switch operation” in this section.)

5)Select Weld Mode. (Refer to Control Box Operation in this section).

6)Use Control Select switches, increment/decrement switches, and encoder knobs to set desired para- meters for weld depending on what options are installed. (Refer to Control Box Operation in this section).

7)Feed the electrode through the gun and cable and then cut the electrode within approximately .38" (9.5 mm) of the end of the contact tip for solid wire and within approximately .75" (19mm) of the exten- sion guide for cored wire.

8)Connect work cable to metal to be welded. Work cable must make good electrical contact to the work. The work must also be grounded as stated in "Arc Welding Safety Precautions".

WARNING

When using an Open Arc process, it is necessary to use correct eye, head, and body protection.

____________________________________

9)If used, be sure shielding gas valve is turned on.

10)Position electrode over joint. End of electrode may be lightly touching the work.

11)Lower welding helmet, close gun trigger, and start welding. Hold the gun so the contact tip to work distance gives the correct electrical stickout as required for the procedure being used.

12)To stop welding, release the gun trigger and then pull the gun away from the work after the arc goes

out and Postflow time, if used, is over.

13)If required, starting can be optimized by adjusting the acceleration and/or run-in speed. (Refer to Control Box Operation in this section).

WIRE REEL CHANGING

At the end of a coil, remove the last of the old elec- trode coil from the conductor cable by either pulling it out at the nozzle end of the gun or by using the follow- ing procedure:

1)Cut the end of the electrode off at the gun end. Do not break it off by hand because this puts a slight bend in the wire making it difficult to pull it back through the nozzle.

2)Disconnect the gun cable from the gun connector on the Power Feed 10 Dual wire drive unit and lay the gun and cable out straight.

3)Using pliers to grip the wire, pull it out of the cable from the connector end.

4)After the electrode has been removed, reconnect the gun cable to the drive. Load a new reel of elec- trode per the instructions in “Wire Reel Loading” in this section.

WIRE FEED OVERLOAD PROTECTION

The wire drive has solid-state overload protection of the wire drive motor. If the wire drive motor becomes overloaded for an extended period of time the wire drive will issue a shutdown command to the Control Box and force itʼs status light to blink between green and red. The Control Box turns off the power source, wire feed and gas solenoid. The status light on the wire drive will continue to blink between green and red for about 30 seconds before the wire drive will auto- matically reset. At that time, the wire drive will issue a shutdown over command to the Control Box that will return the system to normal operation. The wire drive will force itʼs status light to solid green.

Overloads can result from improper tip size, liner, drive rolls, or guide tubes, obstructions or bends in the gun cable, feeding wire that is larger than the rated capacity of the feeder or any other factors that would impede normal wire feeding. (See “Avoiding Wire Feeding Problems” in the MAINTENANCE section).
