have been feverishly consuming the welding videos while awaiting delivery of my first welding unit, and a string of field projects for it. I've splurged for Lincoln Power MIG 210 trying to buy enough machine to cover all my basic work requirements. The specs by the way limit you to 175 amps in stick mode, but you have 220a available in MIG. This said, I'm starting to have doubts if my seller is going to deliver, so I might be ordering elsewhere....with option of choosing a different machine.
I'll get right to it:
Following mucho practice and some instruction, my first projects will be repairs and a custom upgrade on my steel dumpsters. 1/8" patches via mig....and will use this for some stick practice also to get a feel for the machine. But the upgrade...that will involve 1/4" tube and 3/8" plate, and must be strong!! ***So I want to know if I'm buying enough machine to do this - is the short version of the question.*** The extended version and details of this question to follow.
The chart of settings I've also attached from the manual only goes up to 3/8" plate - does not suggest mig for this, leaving their only recommended setting 1/8 stick "E6011 / 56013 (DC+)" 160-175 amps - again 175a being the max the unit does in stick mode.Please see the attached photo
These are 10-12 yard dumpsters - not monster 20 or 30s - BUT, this upgrade is so my larger 33,000gvw truck can pick them up when they are too heavy with e.g. fine rubble and the smaller Isuzu can not lift. So I want it to be plenty strong.
So the questions please:
1) Do I have enough power in this machine to weld the 3/8" plate to the 1/4" tubes? Is 2 passes a sound plan for this - and mig or stick? I really do like the ease of use of this machine with its interface, and that it's not an import with questionable specs/customer service as with some, but perhaps not all of the import companies.
2) I'm concerned about not being able to use 7018 (manual says max 5/16" with that electrode) for that 3/8" to 1/4" weld, by the specs - but wouldn't 7018 ideally be a better choice than 6011 for strength? Or should I try say first pass with 6011, then two more passes with 7018?
3) Should I be considering an additional and/or more powerful machine? Thoughts include:
a) One machine: Everlast Power Mts 250S http://www.everlastgenerators.com/produ ... ermts-250s - not as easy to set, and an import, though perhaps one of the better ones. Max 200a stick 250 mig. More money than the Lincoln by about $400. The Tweco FABRICATOR 211i attractively priced about $950 and goes up to 200a stick, 210a mig.
b) One more expensive machine: Tweco 250i http://store.cyberweld.com/tharcfa25miw.html More impressive specs with 230a stick output. Again less enthused about the interface/import. And at about $600 more....hell I think I've talked myself out of that one given option C.
c) Two machines: Keep with the Lincoln, but order a more powerful stick only machine such as a 300amp Everlast or other 250a import - only to pull out for 3/8"-1/2" type work.
Would a 200a DC stick only unit do the trick for 3/8-1/2"? It's 25 amps more than what I'd already have in Stick mode with the Lincoln (not sure how much real world difference that makes especially comparing Lincoln spec to an import spec)....though for $350 I really like the sound of the portable 120/240 Everlast stick only welder 200a with dedicated 6010 port. The 300a version is just under $600.
I don't want to go the buzz box or AC route...want to stick to DC only so that eliminated the Lincoln or the Hobart Stickmate.
Thanks in advance - I know there's allot of detail in there!
