Solar welding !
With SAXO 3.0 supplied with solar photovoltaic electricity

SAF experimented with "le Club des Utilisateurs de Photopiles" (Mr Alain RINGNET, 14, rue des Champs 53250 MADRE) a use of a SAXO range welding set  (coated electrodes applications, for maintenance and repair works) with solar photovoltaic electricity.

 

 

Here is the Mr Alain RINGNET's  testimony:

Experiment situation:

"The house, located in the South of Spain, is far from the local electric network 

The electricity is coming from photovoltaic solar panels which are connected to a 48 volts - 400 A/h storage battery. This direct current electricity is transformed into 230V alternative current as the EDF one in France or the SEVILLANA one in Spain, thanks to an inverter of 3.5 kVA power."

Testing types and works:

"Tests of welding works were done with 2.5 mm diameter rutile and stainless steel electrodes.Then, building works of the garage doors were done with SAXO 3.0 set"

Measurement equipment used:

"A numerical  voltmeter and an ampere meteric clamp"

Observations:

"All the people who tested the welding set SAXO 3.0 were well-surprised by the excellent quality of the welding. Spanish masons who were on the worksite were particularly astonished by the lightness of the equipment and the easyness of the welding sticks striking. They would have bought this kind of equipment... I gave them SAF France contact information. They informed me that they haven't seen yet this kind of power set in Spain.

With a 2.5 mm diameter stick, the maximum of direct current power measured and used was of 2.6 kW  that is to say 50 A under 52 Volts (battery voltage); with an 0.9 output inverter, the consumption in alternative current was 2.3 kVA. 

What is new, is that you can weld with a SAXO 3.0 even in an isolated place from the electric network even without power generating unit group. With power generating unit of the lower range (3 kVA power), the welding set works too but I noted that striking was more difficult."
