HOT INCH

Hot inch occurs when the trigger is pulled and an arc is not established. After a 1.5 second period, the Sequencer will jump to the Weld state and the wire feeder will run at the preset wire feed speed on the dis- play. The wire is hot (output is on) at this point. Start, Upslope, Downslope, Crater, Burnback, Postflow, etc are all skipped when Hot Inch is activated.

FOOT AMPTROL

A Foot Amptrol Kit can be installed in order to operate the output of the machine using a pedal. Located on the Control Box, the Right encoder turns output on/off if desired. The left encoder sets the max work point limit. When the pedal is pressed OCV will be present and gas will not flow. As soon as the tungsten touches the work and there is current flow, the gas solenoid will turn on. If the arc breaks the machine will enter the postflow state. When the postflow timer expires, the machine will return to OCV mode and no gas will flow until the arc is established. If the pedal is released it turns the machine off, postflow will be entered until time out. When the postflow timer expires the machine will return to idle state and wait for trigger. Preflow will be presettable for external triggers if desired. Triggering machine with encoder will skip preflow.

WIRE DRIVE -- PC BOARD ADJUSTMENTS

ELECTRODE POLARITY:

The system needs to be aware of the electrode polari- ty. A DIP switch setting on the Wire Drive PC boards is used for this purpose. See INSTALLATION Section “Setting DIP Switches in the Wire Drive”.

GEAR BOX RATIO:

The systems needs to know which gear has been installed on the Wire Drive, low or high speed. A DIP switch setting on the Wire Drive PC boards is used for this purpose. See INSTALLATION section“Wire Drive Ratio” for information on how to set the DIP Switch.

WIRE REEL LOADING - READI-REELS, SPOOLS OR COILS

To Mount a 30 Lb. (14 kg) Readi-Reel Package (Using the Molded Plastic K363-P Readi-Reel Adapter:)

The Spindle should be located in the LOWER mounting hole.

1)Depress the Release Bar on the Retaining Collar and remove it from the spindle. See Figure BB.4.

2)Place the Adapter on the spindle.

3)Re-install the Retaining Collar. Make sure that the Release Bar “pops up” and that the collar retainers fully engage the retaining groove on the spindle.

4)Rotate the spindle and adapter so the retaining spring is at the 12 o'clock position.

5)Position the Readi-Reel so that it will rotate in a direction when feeding so as to be de-reeled from bottom of the coil.

6)Set one of the Readi-Reel inside cage wires on the slot in the retaining spring tab.

7)Lower the Readi-Reel to depress the retaining spring and align the other inside cage wires with the grooves in the molded adapter.

8)Slide cage all the way onto the adapter until the retaining spring "pops up" fully.

CAUTION

Check to be sure the Retaining Spring has fully returned to the locking position and has SECURELY locked the Readi-Reel Cage in place. Retaining Spring must rest on the cage, not the welding electrode.

9)To remove Readi-Reel from Adapter, depress retaining spring tab with thumb while pulling the Readi-Reel cage from the molded adapter with both hands. Do not remove adapter from spindle.
