EQUIPMENT SERIES
Automatic busbar welding
Suzhou SC-Solar Equipment Co., Ltd. ↗This station solders the bus ribbons that connect laid strings into a module circuit. SC-Solar quotes 15 seconds or less per module and adds false-weld detection, flux monitoring and automatic nozzle backflush.
Busbar punching and black-paint removal are optional on this machine, so price them separately. The glass-size line in the catalogue reads as two sizes with no label for length or width; ask SC-Solar for a dimensioned drawing.

START WITH YOUR PRODUCTION TASK
Pick it when you want bussing automated with built-in weld checks. Send your ribbon, flux and string layout, choose the options, get the size range drawn, and accept the machine on measured joints and cell condition over full monitored cycles. If you would rather combine layup and bussing in one frame, compare it with SC-Solar's integrated layup and bussing machine.
SOURCE-LINKED DATA
Published specifications
Values below are published by the manufacturer, each with the date its source was checked. Ask for the figures that apply to your configuration and material in the quotation.
The manufacturer has not published a complete specification table for this entry. Request the exact offered drawing and operating limits.
01 · Manufacturer information
What the weld monitoring covers
SC-Solar describes cell correction followed by busbar welding, with false-weld detection, flux monitoring and backflush cleaning of the nozzle. It also stresses continuous feeding and easy service access. The page does not say how detection works, how often it raises false alarms, what flux window it holds, or what joint strength and resistance it achieves. Ask for those figures and the solder recipe with your quotation.
Punching and black-paint removal add process steps and materials, so ask for each as its own line in the offer. The glass row lists 1640×2650 mm and 900×1500 mm without saying which is a minimum, a maximum, a length or a width. Read it as SC-Solar printed it and get the real envelope on a drawing. The small insulating pieces between busbars and cells come from SC-Solar's insulation sheet placement machine, so check both drawings together.

What to put in a bussing enquiry
Materials and layout
Ribbon and busbar coating, solder and flux, the string and module drawing, and whether you need punching or paint removal.
Joint quality
Resistance, pull strength, appearance and cell-crack limits, with test positions and sample sizes.
Weld and flux checks
What the detection covers, its thresholds, what happens on a false alarm or reject, and which records it keeps.
Upkeep
Nozzle and backflush care, consumables, fume extraction, cleaning and continuous feeding, with SC-Solar's procedures.

Trial plan for joints and monitoring
Settle the build
Sign off the size range, materials, options and weld recipe.
Test the joints
Measure electrical and mechanical results and check cells at every specified weld position.
Try to fool the detector
Feed agreed faulty welds and poor flux conditions and see whether they are flagged and logged.
Run like production
Include feeding, backflush cleaning, pattern changes and stop recovery in the counted output and consumable use.

Buyer questions on auto bussing
What glass sizes does it take?
The catalogue line is ambiguous. Ask SC-Solar for a drawing with the limits marked.
Will false-weld detection catch every bad joint?
SC-Solar gives no detection rate. Test it with known bad joints during acceptance.
Are punching and paint removal standard?
They are listed as options; have them named in the order if you need them.
