20) Reliable connection: The connection between the welding machine and the power supply, between the
welding machine and the welding torch, between the welding machine and the electrode holder, between
the welding machine and the wire feeder and between the welding machine and the earth cable should
be reliable, and the connection of all kinds of control cables should be reliable as well. Improper
connection would cause poor contact, which would lead to malfunction, resulting in abnormity and
burnout, etc.
21) Connection with the workpiece: If someone uses steel plate or steel bar instead of the cable
connecting the workpiece, the resistance would be greater, and the welding current would be unstable.
Besides, overheating would lead to fire hazard. Therefore, please connect the base metal reliably
with normal insulated cable.
22) Take protective measures when welding in windy environment. Otherwise, the shield gas would be
blown away and air holes would be caused.
23) Clean the base metal before welding if there is any oil, rust, paint, moisture or other matters
on the surface of it. Otherwise, air holes or cracks would be caused, and good welding effect could
not be obtained.
24) Special tractor is available for integrated machine, and users can fix the machine and cylinder
on the tractor. However, for separate machine, no fixed location is available for the cylinder,
and users should ensure that the cylinder is securely fixed by themselves.
