Ersa ECOSELECT Nozzle Setup Guide: Available Sizes and Configurations

The Ersa ECOSELECT series provides compact, efficient selective soldering for medium-volume production lines. Setting up nozzles correctly on ECOSELECT machines is essential for achieving consistent solder quality and minimizing cycle time. This guide covers available nozzle sizes, common configurations, and setup best practices.

Key Takeaways

**ECOSELECT machines primarily use B14.1/B22 base type** — the same base as most VERSAFLOW models

**H=47 is the standard nozzle height** — matching the compact ECOSELECT solder pot design

**Start with 3-5 core nozzle sizes** — then expand based on your specific PCB requirements

**ECOSELECT 2 and ECOSELECT 4 have specific pot configurations** — verify your model before ordering

**All replacement nozzles are aftermarket compatible** — brand names used only to indicate machine compatibility

Setting Up Nozzles on ECOSELECT

Nozzle Installation Procedure

1. **Prepare the solder pot** — Ensure the pot surface is clean and dross-free before nozzle installation

2. **Verify the base type** — Confirm B14.1/B22 (or B16.1/B36 for specific models) matches your nozzle

3. **Insert the nozzle** — Thread the nozzle into the solder pot, ensuring it seats firmly without cross-threading

4. **Start the pump** — Begin the solder pump and observe the wave formation

5. **Check wave quality** — Verify the wave is symmetrical, consistent, and reaches the target height

6. **Test on sample PCB** — Run a test solder cycle on a sample board before starting production

ECOSELECT Dual Pot Configuration (ECOSELECT 4)

On ECOSELECT 4 machines with dual solder pots, each pot operates independently:

**Left pot** — Typically configured for smaller nozzles (3.0/6.0 or 4.0/8.0)

**Right pot** — Typically configured for larger nozzles (6.0/10.0 or 8.0/12.0)

Each pot can use different solder alloys if needed

Each nozzle must match its respective pot base type

ECOSELECT Nozzle Maintenance

ECOSELECT machines run continuously in medium-volume production, making nozzle maintenance critical:

FrequencyActionEstimated Time

|---|---|---|

DailyWipe nozzle tips, skim dross3-5 min per pot WeeklyFull cleaning with IF930 paste10-15 min per nozzle MonthlyDimension check, replacement planning15-20 min per nozzle

Use IF930 cleaning paste (179904 or 179905) and matching brushes (258787 for small ID, 247811 for medium ID) for weekly maintenance.

Common ECOSELECT Setup Mistakes

1. **Wrong base type** — Installing B14.1/B22 nozzle on a B16.1/B36 pot (or vice versa) causes seating failure

2. **Insufficient height** — Using H=47 when the fixture requires H=57, resulting in inadequate wave contact

3. **Too wide ID** — Using 8.0/12.0 when 4.0/8.0 is needed, causing solder to contact adjacent components

4. **No daily maintenance** — Skipping wipe-down leads to oxide buildup and inconsistent wave quality
