電焊機殼、氣焊工均為特種作業，應身體檢查合格，并經 技術學習、訓練和考試合格，領取《工種操作證》后，方能獨立操作。工作前檢查焊接場地，氧氣瓶與乙炔氣瓶相距不小于5m，距施焊點不小于10m。并在l0m以內禁止堆放其它易燃易爆物品，(包括有易燃易爆氣體產生的器皿管線)，并備有消防器材，足夠照明和良好通風。
作時(包括打渣)所有工作人員穿戴好工作服，防護眼鏡或面罩。不準赤身操作，仰面焊按應扣緊衣領、扎緊袖口、戴好帽、電焊作業時不得戴潮濕手套。
受壓容器、密閉容器、各種油桶，管道、沾有可燃氣體和溶液用的工件進行操作時，事行檢查，并經過沖除掉有毒、、易燃、易爆物質，解除容器及管道壓力，容器密閉狀態(敞開口，旋開蓋)，再進行工作。
焊機外殼的結構及性能和幾種分類
1、焊機外殼品質分析。包括：多維分析、功能分析、效益分析、用途分析、檢查表、品質擴展、模擬產品試驗、系統分析、性能分析、等級設計、弱點分析等等。這類方法的依據是：機柜機箱新的設想可以通過分析已有的產品而獲得。
2、焊機外殼需求分析。包括：綜合列表法、問題分析、缺口分析、市場細分化、相關歸類等等。這類方法的注意力集中在機柜機箱需求上，可以通過研究長期使用某類產品的企業或個人獲得啟示。
3、機柜機箱關聯分析。包括：兩維矩陣、形態學矩陣、強制關聯、類推、自由聯想等等。這類方法是強迫或刺激我們驅動大腦用新的或不尋常的方式去看待事務，尋找事物之間新的聯系，而不是常規聯系。
4、機柜機箱發展趨勢分析。包括：自由遐想、起因趨向、趨勢預測法、趨勢區域、熱門產品、報紙、假設方案等等。這類方法主張應從對付未來工作和生活環境的預測來刺激新產品的設想。
5、機柜機箱群體創造力。包括：頭腦風暴法、多學科小組法、集思廣益法、德爾菲法、思考機柜機箱、集體筆記本法等等。
