MRN-1200S

Operability and visibility are greatly improved
by the touch-type operation panel. Welding conditions can be easily set and checked by adopting the touch-type operation panel.

Equipped with a memory function for
welding conditions By storing the welding conditions in advance and reading out the conditions according to the stud diameter, welding can be performed quickly and easily (20 types of conditions can be stored).

● Compact and lightweight type with casters for easy movement
Large casters are used, and the small size and light weight make it easy to carry out on-site work and move.

Supports a wide range of three-phase 200V/220V/400V input voltages Supports
3 different input voltages by switching the input voltage tap inside the power supply

● Short-cycle arc stud welding is possible for sheet metal Arc stud welding of
sheet metal and cases is facilitated by using small-diameter studs and short-time energization.

GSK-221

Compact and lightweight welding
gun Welding work is easy with a compact welding gun.
