More welder info
One thing no one has mentioned is duty cycle. How long can you weld at a particular amp setting before you overload or damage the welders internal parts, to weld a car frame at higher amp settings a 110 V welder is probably at only 30 % . My lincoln 255 square wave does Tig, ac and Dc and arc and can weld at 200 amps all day long..at a 30 % duty, The manufacturere recommends that you only weld for 3 minutes out of every 10 without damaging the machine. sooner or later you probably want one of every kind. A stick welder with 6011 AC (farmer rod) works when repairing painted or rusty farm machinery. You can soak 6011 AC rod in water then turn up the amps and "cut" burn metal with the heat and poke method. Tig welding requires more skill and manual dexterity, contaminate the tig electroda and you have to resharpen and mabe grind out part of your weld. If you use a 110 V mig you will want to be sure to bevel and Gap your weld joints to get proper penetration. I keep a box of horse shoe nails in the drawer, they are miniture wedges, make a tack , check alignment and if needed a nail to widen the gap before the next tack , as mentioned earler with a 110 V with a gas torch, make multiple passes for thicker material. Flux core leaves a coating of slag that should be removed before another pass to get a good strong weld. .
