Quick Welding Question:
Im about to weld on LCA skids, upper C gussets & a homemade truss,, question is should i un-bolt the lower/upper control arms before i weld the skids on, & will welding on the 30's housing do any damage to the inner seals which are brand new, or the upper ball joints??
((Im using an old Lincoln 250 arc welder & probably 6011 rods at 120amps give or take))

Well the one issue i have with this welder is that its hard to start an arc below 110 & at 125, it can burn thru 1/8th if ur too slow!! I do have 1/8th 6011 rods, but i make my best welds with 3/16th rods on this machine. ((everything is cleaned before i make my welds!!))

Thats funny i just got done welding on my home brew truss and i used a 140 wire feed with flux core wire.But its only capable of welding up to 1/4 in so burning through was not a concern.How ever ive only had my wire feed a couple of months and before that my Lincoln buzz box was my go to machine.I found that smaller 1/8 5/32 at about 90 amps worked better for me on more precise 1/4in and slightly under material.I took some pics as i went along on the truss I will post them as soon as i figure out how to down load them.

I took some pics as well welding a piece of 3/16 to 1/4 with a 3/16 6011 rod. I started at 125 amps for a 3" bead, then down to 115ish, & then about 105ish (its a big crank wheel & numbered 100-125-150 etc, so its best guess when in-between, lol).
The 1st 3 inches u can see the 3/16 was burned thru a bit & was too hot, second pass was better but still a bit hot, 3rd pass was the best but u can see the 1st inch i had trouble maintaining the arc & was inconsistent till i steadied it out for the second 2 inches.
Like i said, once ur around 100 amps, its hard to strike an arc & start a good bead, even using the "lighting a match stick" method thats reccomended!! (there cell phone pics so not so great to post).
