Common Questions
10 totalHow many basic sewing patterns does the He-800A come with?
The He-800A comes with 21 basic sewing patterns as standard. Additionally, up to nine original sewing patterns created with the optional sewing data programming software can be added. Stored sewing patterns made by setting details with basic patterns can be saved up to a limit of 90 patterns. (Page 1)
What is the maximum sewing speed of the He-800A?
The maximum sewing speed of the He-800A is 4,000 stitches per minute. The machine uses a 1-needle lockstitch mechanism. (Page 4)
What type of needle does the He-800A use?
The He-800A uses a Schmetz Nm 134 needle. This specification is listed in the machine's official specifications table. (Page 4)
What is the buttonhole size range supported by the He-800A?
The He-800A supports a cutter length range of 4.0 to 32mm. The maximum sewing width is 6mm and the maximum buttonhole length is 40mm. (Page 4)
What power supply options are available for the He-800A?
The He-800A supports both single-phase and three-phase power supplies. Single-phase options include 110V, 220V, and 230V at 600VA, while three-phase options include 220V, 380V, and 400V. (Page 4)
How does the He-800A prevent poor stitching at the start of sewing?
The He-800A uses a bobbin presser to prevent the bobbin from spinning free when the lower thread is trimmed, making lower thread feeding more stable. Additionally, a lower thread holding device holds the lower thread at the sewing start to ensure that the thread end is sewn into the seam properly. (Page 2)

Electronic lockstitch button holer Providing a wider variety of sewing patterns Sewing patterns made by setting details with basic patterns can be stored up to the limit of 90 patterns. The selection and resizing of the sewing patterns can be made on the operation panel. Furthermore, up to nine original sewing patterns created with the sewing data programming software (optional product) can be added. 21 basic patterns are provided. Original sewing patterns can be added. Electronic operation provides a much greater number of sewing pattern variations and a dramatic improvement in sewing quality.

･ 21 basic patterns are provided. Original sewing patterns can be added. ･ Adjustable presser foot lifter height makes insertion and removal of the material easier ･ Quick and accurate double position cutter operation Rectangle Rectangle-radial Rectangle-round Rectangle-taper tack Rectangle-tack Radial-rectangle Radial Radial-round Radial-taper tack Radial-tack Round-rectangle Round-radial Round Round-taper tack Round-tack Eyelet-rectangle Bar tack Eyelet-radial Eyelet-round Eyelet-taper tack Eyelet-tack Easy operation Easy positioning ･ The presser foot lifter is driven by a pulse motor, so that the height can be adjusted as desired (standard function) for when the pedal is at the neutral position and when it is depressed forward (two stages) and backward. This makes insertion and removal of the material easier and reduces working fatigue. ･ The presser foot rises only by the height necessary, so that the time needed for it to rise and drop can be shortened.
Double position solenoid Purl stitch Whip stitch Easy operation No need for adjustments such as replacing cutter cams when changing number of stitches The cutter vertical movements is driven by a double position solenoid. If not using a cutter, the cutter operation can be deactivated at the press of a key. The cutter operates without slowing down the sewing machine, and the cutter response time is also fast, so that cycle time is reduced and productivity is increased. Sub-table provided as standard It eases the setting of the material and reduces operator fatigue. Gives perfect sewing finishes Wide sewing range The thread take-up, rotary hook and thread path mechanisms provide ideal balance, so that attractive buttonholes can be sewn in a variety of different materials under a variety conditions. Accurate cutter operation The cutter vertical movements is driven by a double position solenoid, so that the material is cut more acurately. Clean finish with no upper thread trailing length Attractive finishes are obtained with no upper thread trailing at the sewing end. This ensures a stable and consistent high-quality sewing finish is always obtained. Better stitches at the sewing start Adoption of a bobbin presser prevents the bobbin from spinning free when the lower thread is trimmed. This makes lower thread feeding more stable and produces better stitches at the sewing start. And the lower thread holding device holds the lower thread at the sewing start to ensure that the thread end is sewn into the seam properly. Quiet operating environment Adoption of a clutchless mechanism ensures quieter operating environment and increased durability. Accurate home position detection The home position sensor incorporates a non- optical proximity sensor, so the sensor is not subject to operating errors from oil or dust, and cleaning oil and dust from the sensor are also unnecessary. Easy threading The needle bar can be moved to the right as a matter of course, and this makes threading much easier. Simple and easy-to-use operation panel There is a program memo pocket provided on the back of the panel. This lets the operator keep necessary information such as a parameter table, program notes and an error code table on hand for easy reference. The operator can select panel position whichever above or below the work table. Purl stitch / Whip stitch The upper thread tension is controlled by a solenoid, so that setting between purl stitches and whip stitches can be done simply by selecting them on the operation panel. Fine adjustments to the upper thread tension are made using a thread tension nut. The same method that operators have become used to allows the optimum thread tension to be easily obtained. Ideal for sewing vertical buttonholes A large arm pocket allows smooth material setting. Buttonhole sewing is also possible with the machine head positioned horizontally to the operator, which fully utilizes the large arm pocket.

Mechanical button holer With under lay Without under lay Gives perfect sewing finishes Stable zigzag seams even at high speed A new needle zigzag mechanism (patent acquired) reduces the effect of vibration from upper shaft rotation on the needle bar, so that stable and accurate needle zigzagging is obtained even at high speeds. When sewing speed has been changed, a knife is not used to trim the thread. The cutter space does not change, further making sure that the finish is attractive. Adjustment of zigzag width balance is possible The left and right stitch width ratio for buttonholes can be set on the operation panel. Under lay Up to four pattern can be combined and sewn together. RectangleSaw shape
Options Needle plate set, RB The elasticity of rubber is used to make cutting more accurate by stopping the cutter from getting stuck in the material and not returning. Tape guard winder For materials which stretch extremely easily, such as all types of knitted materials, stronger buttonholes can be sewn if tape is attached to the underside of the article being sewn. Ruler This makes buttonhole positioning quicker and more accurate. Sewing data programing software This is a software package which lets you create new patterns using a personal computer. It can be used to program any patterns other than those patterns which have been pre- programed. (A P-ROM writer is required.)
