Re: [MW:5243] Use of MIG filler wire as a TIG welding filler wire

Dear Mr. Hitesh,

 

The TIG and MIG filler wires are  manufactured as per same SFA specification only difference is that you get in spool form for MIG welding and cut length form for TIG welding.  You can use the MIG wire for TIG welding with out any deviation in properties.
