1. As coolant for all liquid-cooled torch systems, we recommend the special BINZEL coolant BTC-15,
which remains liquid down to -15°C.
Features of BINZEL Coolant BTC-15:
• Non-conductive with regard to no-load voltages and operating voltages, in the sense of welding
technology.
• Important for all torches using HF, and/or using two potentials, such as plasma torches and for all
grounded, metallic coolant tanks.
• Prevents electrolytic corrosion when using torches made from different metals and torches with small
diameter cooling channels.
• Increases life of torch, cable assembly, pump and cooler.
• Non-toxic for humans and safe for the environment (see data sheet).
2. Must be used in conjunction with an adequate motor protection device.
3. A water flow cut-off switch (850.0033) is recommended for each torch when MIG welding to protect
the torch from overheating in the event of insufficient liquid flow.
Please note that the pump and motor will not be covered by warranty as variables such as coolant quality,
purity and coolant level, as well as the proper installation according to 2. and 3. are beyond our control.
