Other inspections of welding equipment, appliances and working environment
2. Carefully checking whether welding is allowed in the surrounding working environment before work. Only when it is confirmed to be normal can the work start. The flammable and explosive materials must be inspected before operation. If necessary, it must be removed before work can be done.
3. Electric welding machine of the input and output must be firmly connected, which should be reliable grounding wire. The insulation device of electrode holder should be well arranged. Electric welding machine working temperature is not more than 60 ℃ ~ 70 ℃.
4. Paying attention to check the welder and regulator. More than 60 °C temperature should be cool. The secondary voltage during welding should not deviate from 60-80v (v). Finding fault, broken wire, fuse burned again and again should be shut down for maintenance or replacement.
