The welder has to use both hands — one hand holds the welding gun, while the other hand holds the
welding rod. Certain thermoplastic materials may produce obnoxious odors or even poisonous fumes
when being welded. Precaution notices issued by the material supplier should be followed. If in doubt,
weld in a well-ventilated area and avoid excessive inhaling of any fumes. Common welding goggles or
helmets are not required.
Cutting pliers or a knife must be available to the welder to angle-cut the welding rod. The welding rod
should be cut at an angle of approximately 600F before starting. One of these tools is also necessary for
cutting the rod after welding.
