DESCRIPTION
FEATURES
Arc sensitivity is selectable by changing the tap of a reactor.
3 kinds of applicable wire diameters are available.
Secondary short circuit protection is the standard function.
Crater voltage and crater current control are possible.
Fresh tip treatment and burn back time control are realized.
- KR2 series uses a special control circuit to achieve low spatter welding in short circuit and spray transfer in C02/MAG welding.
- The arc starting circuit allows virtually 100% arc start success in any operating mode which makes it possible to use this model in both semi-automatic or automatic welding equipment.
- In simplified unitary mode, the welding current setting on the remote controller automatically determines the corresponding
welding voltage.
