LEAD FREE RETROFIT KIT
The Lead-Free Retrofit Kit is a cost effective solution to upgrade an existing machine for lead-free operation without the need to purchase a new wave solder machine or replacing the entire solder pot.
RETROFIT KIT DETAILS
Made of all titanium construction, the Lead-Free Retrofit Kit is highly resistant to the corrosive effects of lead-free solders and affords significantly improved longevity compared to surface coated alternatives. Winner of the coveted 2005 SMT Vision Award, the innovative Lead-Free Retrofit Kit is compatible with all major brands of wave solder machines and can be easily installed in all popular models.
