DN-16.25.35.50.75.100.160
Pneumatic resistance Welding Machine
Brand: RENHAN
1 Adopt integrated pressure cylinder, ensure stability, mobility of pressurizing and the welding speed.
2 Microcomputer controller: with functions of automatic constant current, preheated current setting, welding current, temper current, failure diagnosis, automatic protection, ten welding criterion storage.
3 Main transformer adopts low resistant designing, secondary conduction adopts upper insulation manner to avoid short circuit.
4 Adoption of multi-accesses coercive water cooling system, cool and protect the main transformer, controllable silicon and electrode water, ensure long-term credible running.
