How to weld thin sheet metal with arc welder.

The stitch welder has a solenoid that pulsates the rod and also a diode that can be engaged to convert the buzz box output to dc. Just grab a piece of sheet metal to get the heat set correctly and go to town. Metal inert gas is then used to protect the weld from contaminants. Mig welding is one of the simplest to use for welding.

While welding work back and forth over the seam or opening and cover each area twice in order to properly join 2 surfaces together. For instance when producing a 3 ft. Years ago i bought the stitch welder accessory from them and with the 1 16 electrodes it works well on thin sheet. You ll also need to use an arc welder since a mig welder won t properly join the galvanized steel together.

Weld in the vertical down position weld 6 in. You are basically burning the rods down on top of the metal in straight lines. A good heat setting for 1 8 6011 rods on thin material is about 80 90 amps. If all you ve got is a stick welder and you need to weld some 1 6 mm square hollow section it can be done.

For 3 32 7018 s it s about the same. Mig welding for thin metal. Welding in a sequence that limits the amount of heat can help minimize distortion in thin material. It is an arc welding process that where you feed a solid wire electrode through a welding gun.

Everyone is different but those settings will get you in the right ballpark to weld sheet metal. In order to avoid the usual problems that come with welding thin metal you should carefully consider the process you are using. On larger thin gauge material spread out several smaller welds over the joint. Mig is one of the best ways to weld 20 gauge sheet metal.
