1G—500等离子体切割机是利用电弧使气体电离,并在“热收缩效应”及“磁性—流体动力效应”的作用下产生等离子弧来切割钨、钼、不锈钢、紫铜、铝及铝合金等耐高温、导热性好而易氧化的金属材料。LH—500等离子焊接机是利用等离子焊接薄钢板、钢管、铝、镁及其合金、不锈钢、耐热合金钢、钛等稀有金属及其合金。因等离子体切 1G-500 plasma cutting machine is the use of arc ionization of gases, and in the “heat shrinkage effect” and “magnetic - hydrodynamic effect” under the effect of plasma arc to cut tungsten, molybdenum, stainless steel, copper, aluminum and aluminum alloy, etc. High temperature, good thermal conductivity and easy oxidation of metal materials. LH-500 plasma welding machine is the use of plasma welding thin steel plate, steel, aluminum, magnesium and its alloys, stainless steel, heat-resistant alloy steel, titanium and other rare metals and their alloys. Due to plasma cutting
