Great idea.....especially if you're wanting to grind the welds down flush beveling is a must.
On a side note I see your from Pasco WA. How do you like the area? I worked in moses lake for about 5 months of this year and I thought the locals were rude.
7018 is not "much stronger" then 7014,7013,7024 etc. Do you know what the first 2 numbers in 7018 mean? the same thing they mean in 7014! Also AC is not alternative current it is alternating current. :roflol:
It's up to you. The 10% duty cycle means that you can weld for 1 minute out of every 10. So if you weld for 1 minute straight you have to wait 9 minutes until you can weld again. It only has 2 heat settings so there is no fine tuning. 70 amps max isn't very impressive.
Just depends on what...
Any of the 3 machines should work fine for you.
If you're having trouble with the wire "jamming up" in the drive rollers you need to check the liner,contact tip and insulators for wear and make sure the whip is stretched out on the floor and not kinked. Try to keep it as straight as possible...
I didn't compare 7018 because the comment was that a stick weld is stronger then a mig weld period
I know there are high tensile strength smaw rods out there such as 10018 that would in fact be stronger then a mig weld done with er70. There are also higher tensile strength mig wires out...

Mig is the weakest processes of welding out of the whole bunch. Here a quick list of whats the best to the worst:
1) Submerged Arc
2) TIG
3) Stick/Arc
4) Flux cored
5) Mig
There isn't alot of strength differance between MIG to Stick(50-70MPa depending what electrodes been used) but TIG...
