The MIG 100EN is a dual purpose machine that offers the advantages of standard MIG welding but without the need for gas bottles. Although it can easily be converted to use conventional shielding gases, it is supplied with a special flux-coated wire that produces its own gas shroud as it burns. This feature simplifys its use & makes it more suitable for outside use since there is less chance of the breeze blowing away the shrouding effect of the gas.
