Basic Welding

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before welding.

TO PREVENT SERIOUS INJURY:

Protective gear must be worn when using the Welder; minimum shade number 10 full face shield (or welding mask), ear protection, welding gloves, sleeves and apron, NIOSH-approved respirator, and fire resistant work clothes without pockets should be worn when welding.

Light from the arc can cause permanent damage to the eyes and skin. Do not breathe arc fumes.

Flux-core wire welding is used to weld sheet metal and low carbon steel without shielding gas. MIG welding uses solid-core wire and shielding gas, and is used to weld sheet metal and low carbon steel. MIG welding can also be used to weld thinner workpieces than flux-core welding can.

Good welding takes a degree of skill and experience. Practice a few sample welds on scrap before welding your first project. Additional practice periods are recommended whenever you weld:

•a different thickness of material

•a different type of material

•a different type of connection

•using a different technique (MIG vs. flux)

Make practice welds on pieces of scrap to practice technique before welding anything of value.
