1.The ASK industrial heavy-duty welder with the unique features of
interference-resistance and protection technique ensures excellent
performance in severe condition environment, such as high
temperature, dust, vibration, and big current long-time working.
2.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. KR-500 can output current 570A.
Welding current output for extended 50M integrative cable can still
remain above 460A.
3.This welder offers CO2/MIG/MAG welding with various range of welding wire within 0.8-2.0.
4.Suitable to all position welding, including horizontal, vertical,
vertical, overhead welding on steel plate above 1mm.
5.Applicable to welding on mild steel and alloy. Also to aluminum
when using argon as shielded gas, as well as SS when using mixed
gas as shielded gas. This system is designed to meet the wide range
of welding application, including: boat building, steel structure,
machinery, and hardware.
ASK-KR Advantages Presentation:
1.Employing SMT circuit board in KR series leadingly inside of China
offers guarantee to improve performance, reliability, and
consistency of welding of KR series products. ASK company owns auto
testing & diagnostic device of circuit board and can test all
control parameters on PCBA rapidly. Fully assembled machine has
premium consistency and part interchange ability.
2.Adopting USA DOPUNT NOMEX wire as conducting material of main
transformer and this material is reliable for long time working
under 200℃. All insulation material is rated as H grade therefore ensuring
fully assembled machine can work for high current and long time
under 180℃ maximum.
3.ASK Company employs superior devices and components wholly.
Wholly-sealed dust-proof alternative current contactor with
external cover is used, SCR control module from SanRex, Mitsubishi
(Japan), current sensor from LEM(Sweden) and Tamura(Japan),
electric current and voltage meter from TOKOGAWA(Japan),
temperature sensor from Airpax(USA) are integrated into our system
as well to ensure welding-ability and durability under severe
4.GEORG (Germany) silicon steel sheet automatic cutting lines,
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 assembled machine.
5.This system is equipped with high-class of wire feeder, welding
torch, gas regulator, control cable and working cable. Reliability
of performance is ensured to show the advantage of the fully
6.The lower limit welding current of each KR-500 welder is stable
between 70A and 85A on 1.2mm steel plate under the condition of
using wire in 1.2 and CO2 shielded gas. The welding process is stable, formation good and
suitable for vertical positions welding.
