Product Made in Japan

Manufacturer : Matsumoto Kikai

Model : BH-8DPa

Features

●Various workpieces can be handled
It is also possible to handle various joints and special-shaped workpieces, expanding the fields of application. (workpieces with narrow pipe gaps, workpieces with short pipe sections, etc.)

● 100 items can be stored in memory
Welding conditions are stored as digital values, and welding can be performed stably simply by recalling and setting the conditions on the touch panel. Standard welding conditions (62 conditions *1 ) have been entered.
*1 Shield gas: Ar gas + H2 gas ( 5 %) mixed gas used

-USB memory function
Welding conditions (100 items) can be saved in USB memory by file, and welding conditions can be easily transferred to another control power supply (8DP).

● Standard printer function
Welding conditions can be printed out and retained as back data for welded workpieces, increasing reliability.

● Easy to carry
It is a compact and lightweight power supply, and can be carried easily by holding the handle, making it easy to move.

●Compatible with various fittings
