I thought welding in a patch would be easy....

More of an art than a science - discuss metalworking and welding here.

What do you mean by a new liner?


most welders have a replaceable liner in the cable that feeds the wire to the gun handle if it gets worn or dirty it will cause problems

The liner is what the wire travels through between the gun and the welder. They can get fouled up, kinked, or just plain worn out and wreak havoc with your welds.

yep that what you should get, you can get the coil steel type or a Teflon one either one will work fine.

bad six nailed it. Argon - CO2 mix and .023 wire and a lot of practice.

Thanks for the link! And thank you everybody who stepped in to give me help.

The welder is like brand new, I used it twice. I don't think I would need a liner. But I'm using the spool it came with from the factory, with .30 wire flux core. I think if I can get a tank setup I would have better luck.

Also I asked this question before, but I was told to use a hammer to fold over the sheet metal over the door frame... Now was it supposed to be pre-bent in some type of tool? I don't see me using a hammer on this to fold it over will look good.....

Changing liners is not necessarily a matter of wear and tear. My Lincoln Weldpak 100 came with 2 liners. The manual said to use one with wire >= .030 (usually flux core) and the other liner with wire <= .025 (usually solid core).

Thats nothing just wait you will go out and buy every thing they say to buy and your welds are still gonna look like that lol!

There is a lot more to welding than just having every thing the teacher has its called EXPERIENCE! You only get that by doing it! Loose your actual project parts go find some same size scrap & start laying beads and learn how to weld first.

Some may say that's mean and insensitive to say but any one who knows how to weld thin sheet metal knows its the truth.

Practicing on scraps of the same thickness. Plan around with the wire speed and power settings. Usually on the welder there is a chart on power and wire speed. Use that as a starting point but don't be afraid to try different settings on your practice panels. You are looking for a flat weld with good penetration with a nice consistent sizzling sound. Make sure metal is shiny and clean on both sides or welds will not work. Metal must be shiny where welding clamp is placed. Metal must be clean and free of oils or other contaminates. Change the welding tip frequently. Make sure the welding ground clamp is kept clean and free of corrosion. Watch welding videos on youtube. Make sure welder feed cord is as straight as possible not all coiled up. Practice practice practice on scrap you will get the hang of it. I use "C25" welding gas and .025" welding wire when I weld sheet metal.

I think I'm going to pick up the tank and gas mixture today. A lot with the tips and wire spool.

If you're supposed to tac weld in a panel I don't see how practing laying a bead will make me tac better but I don't mind playing with the welder.
