I believe that a lot of guys on the forum have used that welder to build their smokers so you shouldn't have any issues. One thing to look at is the duty cycle of any welder that you plan on using, the higher that you turn it up the less amount of time that you can weld before it has to cool down. Most of the time it isn't a problem because you'll be making quick, short welds and the machine doesn't have time to get hot but if you start running long beads then you can plan on taking a little extra time. These aren't a reason to not purchase the unit, just a few things to consider while looking for a welder. I'm sure some of the other guys can probably give you some better input.
Great little machine. Leave a little in the budget for a gas cylinder as it’s worth every cent.
I have the same basic machine and have had absolutely zero issues with it over the past 20 years. Consumables are easy to find and it is quick to set up.
I’ve done 0.25 with no issues tho it is definitely at the upper end of its comfort zone. I am also running it on a dedicated 30 amp service line.
I am considering this same welder. I see @Dirtytires recommends the gas over flux wire. School me a bit on flux wire cons. I have heard little uglier welds, but may work better on dirty or rusty materials? Only experience I have is with crackerbox stick welders, and that was years ago.
I used the same welder to build my smoker. I did buy a new gun liner for larger wire. I used flux core for the firebox (1/4" and 1/2") plate. I then used gas for everything else with small wire. I have a dedicated 50 amp breaker.
Remember that duty cycle is based on a 10 minute period. If the duty cycle chart shows 20% at a given amperage/ voltage , at chart setting then the machine is rated to be able to weld continuously for two minutes, out of ten. Then it needs to sit for 8 minutes. Turning amperage down will increase duty cycle and extend weld time, but the tradeoff will be less penetration and smaller welds

Lincoln is a good machine. Gas basically cleans up the bead, no chipping slag or brushing. Flux core you will brush and have some slag. Depending on how much you weld, a 40 cf tank can last a while. Also flux core doesn't work good on less than 1/8 thick steel. The welder your have will meet all of your needs
