Question Quick welding question on my mustang

Hi everyone,

I plan to purchase a Mig with shielding gas welder this weekend hopefully. I want to weld sheet metal by spot welding but I also need to weld support brackets. I looked on HopeDepot.com at the welders they have and there is a Lincoln Weld Pak 125 HD wire-feed for $419. It says it is 30-125 amps for welding and is 110ac. Will this be strong enough for some things more than basic sheet metal? Like if I need to weld the pillars up front, will this work?

Thanks for your help!!

Warren

I built my car with a Millermatic 135, its a 110 unit and it works fine for sheet stock (and lets face it thats what these cars are) but to be honest I wish it had a bit more grunt.

I would try to get just a bit bigger if I were you, im sure that one would work but what about the next project? Building trailers or making a bumper for a 4x4 project ten years from now it will make all the difference.

This is gonna get expensive so be patient. Buy a 140 rather than the 125. It's the limit for a 110V welder, anything beyond that is 220v and its only a few dollars more. Stick with a brand name, Lincoln or Miller. A bottle of 25/75 argon mix is roughly $100 to $150 in initial cost, but $25-35 to refill. Don't forget the regulator. Spend $60 on a 25 foot 10 ga extension cord. To maximize performance its best to use a dedicated 20amp receptacle. Remember, when welding galvanized metal, grind the coating off both sides before welding (PITA). Always have a good ground. Have fun. My 135 Miller has handled anything I've thrown at it, including 3/16 plate with a single pass. Prep is 90%, welding is 10% of the work.

I actually like the 110V over the 220V because you can weld very delicate work. 220 is great if you do allot of 1/8" and 1/4" stock (.120, .188, or .250 thick). Rarely are you going to see metal beyond 3/16" thick on a car unless you're doing older frame work or chassis and roll cage stuff.

I would also add that you can use CO2 as a gas, it's cheap and actually allows for a hotter weld. I worked in a fab shop that used it with a flux wire for maximum resistance to contamination and the high heat.

I used it myself because we had a bar when I was younger and we always had a spare CO2 tank.

I would go with a Hobart 140 mig handler welder, It will be more then enough that your Mustang will ever need. You can get them for around $500 at Tractor supply or places on line.

Been looking at the Eastwood welders and seem to have good reviews.

Once my old Century welder craps out I'll probably get one of these.

I use a Hobart 140 and have welded up to 3/8 metal. The duty cycle is low for that heavy of a metal but for "small" 3/8 jobs it does great. Key is that all metal is perfectly clean.

Thanks for all of the feedback. I looked at the Lincoln 140 and it seems the way to go! Its about $120 more than the 125 model but sounds like the difference is worth it.

I was in your shoes a few years ago and i bought a 110 welder it was ok for body panels etc but soon realised it was not a very versatile machine so i sold it and bought my miller 180 it can go as low as 30 amp and high as 180 amps

I absolutely love this machine and the auto set is a nice feature ... ya its more $$ but when i take into consideration the cost of the 110 unit i bought and sold for a pretty heavy loss this machine is not that much more
