Cold welding cold welding cold welding factory price of cold welding preferred Jie Lite JLT-5188TL Precision Cast Iron repair cold welder introduction: JLT-5188KH Precision Cast Iron repair cold welding and JLT-5188K Compare: power, efficiency high, using 220v industrial power, long uninterrupted work for large enterprises. JLT-5188KH Precision Cast Iron repair cold welding, is to develop in JLT-5188K Precision Cast fill welding and on the basis of a principle by pulse jet technology and digital control, improve process performance arc welding waveform and comprehensive solution cast iron products poor welding performance issues, such as often after welding pores, easy to break, easy to produce white and weld cracks. JLT-5188KT Precision Cast Iron repair cold welding for iron castings, gray iron castings, malleable iron products, all kinds of cast iron welding, welding. With high efficiency, good quality, low cost, convenient operation, high welding and small heat affected zone, no deformation of the workpiece after welding can be machined (including pad drilling, tapping, etc.), weld aesthetic advantages. JLT-5188KH use cast iron cold welding repair method used. The welder uses ≤φ2.5 -5.0 welding. 2. The welding current is 10A-400A. 3. When used in part to be welded cast out of the groove, the groove surface gloss, easy to burn anywhere welding arc groove. 4. When welding cast iron bath formed in ensuring the premise of the duty cycle of the smaller the better, welding pulse frequencies below 5Hz. 5. Linked closely to ensure no broken tracks, we should ensure that each pad must take the community. 6. Long-term work in the oil environment is welders, should go to the oil after cold welding. 7. If the moisture before welding rod should first deal with re-use. 8. pads required machining the workpiece, drilling, tapping pulse should have, and high frequencies.
