Daihen MRN-2500III,GS-203II Stud Welding Equipment
Made in Japan
Manufacturer: Daihen
Model: MRN-2500III,GS-203II
Full-fledged large-capacity thyristor-controlled machine and arc stud gun
Feature:
MRN-2500III
Main features:
●Equipped with the industry’s first microcomputer control
Large-capacity thyristor power supplies are equipped with the industry’s first microcomputer, realizing precise waveform control through digital control.
●Improved arc start and arc stability for small to large diameter studs!
●Significantly improved durability
By changing the on/off of the gun coil from a relay to an electromagnetic contactor, the durability has been greatly improved (long life of about 5 million times).
Useful function:
●Equipped with various protection circuits
・Temperature abnormalities, missing abnormalities, overcurrent, overcurrent, etc.
・Gun current overload protection cuts off the gun current electronically instead of using a fuse breaker.
●Easy setting of minute time Setting of minute time is easy by
using double scale for welding time setting.
Improved safety:
●Avoids the risk of electric shock due to no-load voltage
. Cuts off the output within 0.3 seconds during blank firing.
●Safety design considering drip-proof
GS-203II:
●Increased lifting capacity
●The ergonomic design achieves a good weight balance for workability.
●Reduction of handle temperature rise (expansion of current-carrying area and adoption of heat radiation fin shape)
●Ensures compatibility (consumables and connection compatibility) with the conventional GS-201 and GS-202
