Iv just bought an arc welder. What can i weld with it? And whats she difference between arc and mig welding?
Its second hand and was cheap so i bought it, but dont have any instructions. Looks pretty simple though.
Actually MIG welders (Gas Metal Arch Welding GMAW) are a form of arc welders. The GMAW welder is an electric arch welder that replaces the standard rod with a wire as the filler material. The wire is fed from a spool in the welding machine through the torch and becomes the electrode through which the weld current flows to the base metal. A shield gas also flows through the torch to protect the filler and the base metal weld during the weld process.
I'll guess machine you purchased is a Shielded Metal Arc Welding (SMAW) welder commonly known as a stick welder. The welder inserts a welding rod into the electrode holder and "strikes" the arc to the base metal depositing the filler rod on to the base metal. Most stick welds are on steel or cast iron.
Welding is a knack and takes practice. I would not say it is simple. You must select the correct rod/current/polarity combinations for the base material type and thickness. I started by salvaging 1/8" and 3/16" carbon steel waste from a construction site and practicing. IMPORTANT safeties to remember: 1. The weld flash can blind you -- use a helmet with the correct lens, 2. the weld can burn -- use proper clothing and gloves, have a fire extinguisher and keep combustibles far away from the splatter. 3 weld gases can be hazardous -- weld in a well ventilated area. You might look around for a local trade school - most have 8-12 week night classes for beginning welding. Below are a few web sites that might help.
I hope you have as much fun welding as I do
