S-SW450 Nitrogen Wave Soldering Machine by Southern Machinery

Dross waste, cold joints and corroded conveyor fingers raise the real cost of every THT line. The S-SW450 answers all three with a sealed N2 tunnel, titanium double claw and servo spray fluxing.

What is this machine used for?

The S-SW450 is an inline wave soldering system for Through-Hole Technology (THT) boards, sitting between insertion stations and cooling/unloading modules.

• Power supplies, transformers and heavy multi-layer boards needing dual-edge grip
• LED strips from 50 mm up to 450 mm boards
• Lead-free Sn/Ag/Cu alloys needing inert atmosphere
• High-mix EMS and ODM lines where dross and bridging drop

How the product fits into a complete PCB assembly line

1. Loader or insertion line: THT components inserted manually or by auto insertion.
2. Input conveyor feeds the board into the S-SW450.
3. Spray fluxing coats the board bottom.
4. Preheating activates flux, prevents thermal shock.
5. Nitrogen wave soldering over the double claw wave.
6. Cooling and unloading lock the grain structure.

ROI perspective

A sealed N2 environment can cut solder dross by up to 90%, saving thousands monthly on solder and disposal. The titanium conveyor removes recurring finger-replacement cost. Southern Machinery models ROI case-by-case; no generic guarantees.

FAQ

Does the S-SW450 need a nitrogen generator?

Yes, N2 supply is required, from an external tank or a Southern Machinery generator.

Why a double claw conveyor?

Two contact points keep heavy or thin boards flat over the wave, preventing warpage and flooding.

Is the S-SW450 lead-free capable?

Yes, the titanium pot and conveyor handle Sn/Ag/Cu alloys well.

ROI vs. an air wave machine?

Higher CapEx, but dross savings typically pay back within 12-18 months.
