CuSi3 brazing places special demands on the welding machine, wire feed, and adjustment options.
Even though the process is carried out using the MIG process, not every MIG/MAG welding machine is suitable for it.
Below you will find out why the RED MIG 210 SYN is not recommended for the CuSi3 brazing process.
Classification of the RED MIG 210 SYN
The RED by Lorch MIG 210 SYN can perform MIG/MAG welding and also has a mode for FLUX, TIG, and MMA. It is therefore highly versatile. However, it is clearly focused on MIG/MAG welding.
The processes, programmes, and components have been specifically tailored to this method to enable the best possible welding results with the simplest operation.
If you want to achieve high-quality, clean welds using the MIG/MAG process, the RED MIG 210 SYN is a very good choice.
Brazing or CuSi3 brazing is a process that differs significantly from classic MIG welding.
As such, there are also different requirements for the welding machine welding machine, accessories, and settings
Due to the focus on MIG/MAG welding of steel, there are several limitations for CuSi3 brazing:
Why CuSi3 brazing is not recommended with the RED MIG 210 SYN
Wire feed and torch equipment
CuSi3 wire is significantly softer than steel wire and places high demands on wire guidance and feed.
The RED MIG 210 SYN is equipped as standard with a steel wire liner and suitable wire feed rollers (type W) for soft wires are not available for this device. In practice, this can lead to increased wire abrasion and an unsteady wire feed.
Adjustable current range
CuSi3 brazing often requires very low, finely adjustable currents, especially for thin sheet metal.
The welding current of the RED MIG 210 SYN can be set in the MIG/MAG process between 50 and 200 A. Manual adjustment below 50 A is not possible, but is required for many CuSi3 brazing applications.
CONCLUSION
Even though from a technical perspective CuSi3 brazing is possible with the RED MIG 210 SYN, it is not designed for the CuSi3 brazing process and is not recommended for it.
As a pure MIG/MAG welding machine for steel, however, it impresses with stable processes and easy operation.
