What is the difference between MIG and gasless
What is the difference between MIG and gasless
(OP)
I want to buy a welder for home use. I only have 110 in the garage. What is the difference between a MIG that uses flux gas and the wire welders that don't need gas?





RE: What is the difference between MIG and gasless
I have never used gass-less mig but a friend of mine, with no welding experience borrowed one from a local hire centre to weld up the frame work of an aviary, he had no problem with it. Min thickness is probably 2mm, but MIG with a 0.8mm wire can be used on car bodies.
Note fume from gassless MIG is excessive, best used outdoors.
You will probaly find more info on Lincoln.com web site and if you visit my site www.gowelding.com you will find links to other sites that may tell you more.
Have fun

Three problems that I commonly see with inexperience operators is that they; try to weld too fast, try to push the weld-puddle along trapping slag, have crater cracks. The first two are fairly simple to solve, just practice. The crater crack problem can be solved by restarting an arc at the end of the weld (the puddle-out) 1 to 2 seconds after stopping the weld, fills puddle.
If you are going to be using the self-shielding flux core most welders/wirefeeders require a simple conversion kit to be installed, changing the nozzle tip, and rollers.
Self-shielding flux core does produce an excessive amount of fumes, good ventilation is require.
My personnel recommendation is the Lincoln SP125+
Have fun with the welder
