1.The heavy-duty welder ,adopt SMT circuit board,with unique features of
interference-resistance and protection technique ensures excellent performance in
severe condition environment,such as hight temperature,dust,vibration,and big current long-time working.
2.Small current performance :KR-500 work stably under current of 70A and is suitable for
vertical position welding,overhead position welding and thin material welding.With Φ1.2 welding wire.,
KR-500 are stably stable to weld on 1.2mm steel plate in 70-85A.
3.Extended working cable and unique extra-standard current output are designed to satisfy the
need of long working cable for remote distance and long-time work.
Such as,KR-500 can output current 570A.Welding current output for extended 50M integrative
cable can still remain above 460A.
4.GEORG (Germany) silicon steel sheet automatic cutting line, imported hi-speed punch equipped with hard
alloy machining module are adopted.Burr of single silicon sheet is controlled within 0.03mm.Output
current without load of main transformer is controlled within 2.0A.Thus loss of transformer is low,and
lifetime long,heat radiation low,current attenuation less after long working time.
5.The welder sale all around the world,such as:TAIWAN,TAILAND,,VIENTNAM,HUNGARY,RUSIA,SOUTH KOREA ect.
6.The enhanced products, With high-quality and low-price, can be made competitive bid with the international brands.
