點焊機裝置維護

　　點焊機裝置維護

焊機必需妥善接地前方可運用,以保證人身平安。焊機運用前要用500V兆歐表測試焊機高壓側與機殼之間絕緣電阻不低於2.5兆歐方可通電。檢修時要先切斷電源
，方可開箱檢查。焊機先通水後施焊，無水嚴禁工作。冷卻水應保證在0.15--0.2MPa進水壓力下供給5--30℃的工業用水。冬季焊機工作終了後應用緊縮空氣將管路中的水吹淨以免凍裂水管。

焊機引線不宜過細過長，焊接時的電壓降不得大於初始電壓的5%，初始電壓不能偏離電源電壓的±10%。焊機操作時應戴手套、圍裙和防護眼鏡，以免火星飛出燙傷。滑動局部應堅持良好光滑，運用完後應肅清金屬濺沫。新焊機開端運用24小xiao時shi後hou應ying將jiang各ge部bu件jian螺luo絲si緊jin固gu一yi次ci，特te別bie要yao留liu意yi銅tong軟ruan聯lian和he電dian極ji之zhi間jian聯lian接jie螺luo絲si一yi定ding要yao緊jin固gu好hao，用yong完wan後hou應ying經jing常chang肅su清qing電dian極ji杆gan和he電dian極ji臂bi之zhi間jian的de氧yang化hua物wu，以yi保bao證zheng良liang好hao接jie觸chu。
