INTRA 2100/1400 07.2021 / EN Rev.: A
1.2 Device description
The INTRA 2100/1400 is a robust, high-performance welding control device and
together with the NS 40 B or NS 40 SL welding gun forms a reliable stud welding
system.
When properly used, this device will always provide good, reliable work results.
Welding Process
– Drawn arc process
- Short cycle weld process
High weld performance
INTRA 2100: 2100 A, up to 22 mm weld diameter
INTRA 1400: 1400 A, up to 16 mm weld diameter
High weld safety
This device’s premium characteristics ensure consistently reliable operation and
outstanding work results.
Welding is automatically prevented if there is overheating, a phase failure or an
electrical fault in the welding gun current circuit.
The 35% power reserve ensures automatically ensures safe welding even under
maximum loads and in continuous operation.
High-quality weld results are even achieved with very long connections and under
unfavourable conditions.
Weld current and weld time settings
Continuous adjustment of these two important weld parameters is crucial to
safe, reproducible welding.
Constant current automation
The built-in constant current automation reliably evens out primary system voltage
fluctuations (max. ± 10%) within wide limits up to maximum weld current. Modern
micro-electronics ensure consistent quality of your work results.
Re-release lock
The re-release lock prevents unintentional double welding if the welded stud is still
in the placed welding gun.
