Page 6: Typical Operating Sequence
5.17 An additional sizing operation, swaging, may be required should weld zone exceed tolerances on subsequent processing operations. Micro Products has a special swage tool with exchangeable tooling available to assist with this sizing operation. 5.18 The above operation applies to either auto or manual. When the auto manual switch is in auto, the weld time will be limited to that selected on the timer. -
Page 7: Special Adjustment
SPECIAL ADJUSTMENT HEADPIECE CLOSED SPACE ADJUSTMENT Closed space between dies should be 7/32” when the space- adjusting cam is set at zero. To make this adjustment first move the space-adjusting cam to zero, then check the spacing between the dies. If the space between the dies is not 7/32”... -
Page 8: Preventive Maintenance
PREVENTIVE MAINTENANCE AS REQUIRED: Flashings must be removed from between welding dies and clamp fingers with a brush. If flashings are attached so that they cannot be removed by brushing with a soft wire brush, they may be broken loose with a scraper made of fiber or wood. - Page 9 ANNUALLY: 7.5.1 Remove the movable headpiece and check condition of slide shafts. Wash slide shafts with low residue cleaner, lightly oil and replace headpiece. 7.5.2 Check condition of headpiece castings. If worn or broken, replace with new headpiece. If welder is used in an area where there are corrosive fumes, clean off all oxides and paint where possible.
