Advantage:

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 KR machine has premium consistency and part interchangeability.

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 working environments.

4.GEORG Germanysilicon 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.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 assembled machine.

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 inφ1.2 and CO₂ shielded gas. The welding process is stable, formation good and suitable for vertical position and all positions welding.

7.Excellent machining process, consummate testing approach, considered particulars with this system. Welding performance, reliability, consistency, durability of batch produced whole system has reached higher level domestically and be comparable with imported products of the same class.

8.Parameters of welding current and voltage are easy to be fit and rapidly to be adjusted. Welding performance of KR fully assembled machine has been reached higher level domestically subject to long time researching, testing, test run by many senior welding operators, analysis with wavelets arc analyzer, and testing analysis of hi-speed photography device.
