Wire Feed Welding Choices: How Wire-feed Welders Work, Cost, Function, And More!
Gas metal arc welding (GMAW), also known as MIG (metal inert gas) welding, MAG (metal active gas) welding or wire feed welding, is either an automatic or semi-automatic arc welding process. This process uses a continual and consumable wire electrode and a shielding gas. Both of which are fed through a welding gun. With this type of welding a constant voltage, DC (direct current) power source is the most commonly used power source. However, constant current systems, along with AC (alternating current) can be used. The Northern Industrial MIG welder is a 115 volt, 22-135 amp unit available from Northern Tool. The model number for this product is MIG 135 and its cost $349.99, making it an affordable unit to purchase. This welder is ready to go, right of the box, with the included flux core wire or with shielding gas. This MIG welder has a three year limited warranty and is able to handle mild steel, aluminum and stainless steel. This welder has a duty cycle of twenty percent at 88 amps and is MIG ready with a ten foot long clamp cable. The regulator and gas hose are both included, although shielding gas is not required. The Northern Industrial MIG welder has an eight foot long power cord and has wire feed speed control. The ten foot removable MIG gun uses Tweco style replacement parts. This is a great welder since it is portable and can be used if you do not have access to 220 volts. The Hobart Handler 140 MIG welder (Model number 500500) from Northern Tools is a 115 volt, 140 amp wire feed welder. This unit is box ready and can weld either with or without shielding gas, there is no need for the purchase of additional kits. Made in the U.S.A., the Handler 140 has an amperage output range of 25-140 and it can handle a selection of solid mild steel or stainless steel, flux cored and aluminum wires. Duty cycle is twenty percent at 90 amps, 19 volts and it has a wire feed speed control of 40-700 IPM. The weld thickness for this $479.99 unit is 24 gauge up to 1/4 inch steel and welding wire diameter is 0.023-0.035. While shielding gas is optional, the regulator and gas hose are included. Additional specs for this model include ten foot work lead with clamp, eight inch wire spool adapter, extra .030 inch contact tips and one pound of 0.030 inch self-shielded flux cored wire. This welder is a great alternative to a 220v unit since it is smaller and more portable. Great for large or small jobs, this unit is easy to use for professionals and home welders alike.

Lincoln Welding School Motorsports Program and Hobart Welding School
By Jody Collier
Why am I discussing the Lincoln Welding School and Hobart welding school in the same sentence? Because the 2 schools offer courses that complement each other, are very affordable, and deal with metals you won't study in conventional community college welding programs.

Welder Safety Equipment - Got Long Sleeve Welding Gloves?
By Faye Herl
If you have ever lost a part off of your muffler or had your kid's wagon break, and it was apparent the no bolt will fix the problem, welding has probably come to mind. The system of joining two types of material by add certain types of filler material that in turn can form a mega strength bond, is an excellent trade and awe inspiring process. Safety should always be the first point of concern when beginning a welding project. Safety applications such as welding fire blankets and long sleeve welding gloves, may vary project to project. This depends on the type of welding to be accomplished and the environment where the welding will actually take place.
