ROUTINE OPERATION
Once the procedures and parameters are properly set at the controller the operator should be able to make production welds without changing those settings. A typical weld sequence is as follows:
1. Before starting, make sure that:
a. There is enough wire on the reel(s) to finish the weld.
b. The flux hopper is filled with new or proper- ly screened flux.
2. Energize the power source and wait for it to stabi- lize (all Status LEDʼs Green).
3. Position the Wire Feed Head at the start of the weld. Be sure the
4. Set the travel switch for “Automatic Travel” if the “Hand Travel” position was used to position the feed head in Step 3.
STARTING TECHNIQUES
1.- refers to starting the weld with the WireHot StartingDrive head stationary and the wire not touch- ing the workpiece.
a. Always cut the end of the wire to a sharp point.
b. Press Feed Forward until the wire touches the work piece and the flux hopper acti- vates to put flux around the starting point.
c. Press Feed Reverse to retract the wire 1/8” to 1/4”
d. Use the
e. Press the START button to initiate the weld. f. Press the STOP button to begin the stop-
ping sequence.
h. If necessary, press the Feed Reverse to move the electrode out of the way.
2.- refers to starting the weld
a. Use the
b. Follow the Hot Starting procedure.
- refers to starting the weld with the WireColdDriveStartingHead stationary and the electrode touching the work.
a. This procedure is not recommended for the Power Wave® AC/DC 1000 / MAXsa™ 22 & 29 WIRE DRIVES combinations but may work OK with smaller diameter wires and proper setting of the Start parameters.
b. Follow Hot Starting procedure but omit “step c”.
HEAD POSITION ADJUSTMENTS
The MAXsa™ 22 & 29 WIRE DRIVES can be easily adjusted to any weld position. The most often used adjustments are available on both the MAXsa™ 22 and the MAXsa™ 29 Wire drives. See Figure B.1 Turn the Cross Seam Adjuster (MAXsa™ 29) to keep the arc in the joint as necessary. With a MAXsa™ 22, a K96 or some other means of horizontal adjustment is recommended. See Figure B.2
The entire Wire Drive can be moved into or out of the Mounting Bracket (M6789). If using a K29 Vertical Lift Adjuster it can be locked in either the horizontal or vertical position once the vertical position is set. See Figure B.3.
If the Wire Drive is rotated to a position where the faceplate is upside down, the contact nozzle and the wire straightner and guide tubes will need to be reversed. The polarity of the motor will also need to be changed so the wire feeds in the proper direction. See the Installation Section,
