Default Re: Welding newbie need advice

[QUOTE=flybytaco;270201]pull the wire out of the liner and blow it out with an air hose. inside the machine before you send the wire back into the liner stick the wire through an earplug then into the liner this acts as a wiper and kinda keeps the wire clean before it heads through the gun. just an old trick i've used for awhile[/QUOTE

Good idea. Most weld shops sell wipers just for that purpose....kind of a piece of felt inside a metal clip that you slide over the wire. They also have an aerosol liner cleaner....comes in a can with a small tip. Just pump some into the liner, let it sit, and blow it out. You would be surprised at what comes out the end. Helps a lot if the wire gets slight rust. If it is too rusty, toss it. Makes for poor welds and worn liners.
