Smallest, lightest generator for a MM135?

admin

I've done some searching, but haven't found exactly what I'm looking for...Anyone have recommendations for generator that will run a MM135?   I'm interested in taking my MM135 with me on 4-wheeling/backcountry trips for use as an 'emergency' welder (i.e. repairs that will simply get me or a friend off the trail).   I'm not sure if it's economical to buy a small generator.   Obviously, to save space and lifting weight I'd like the smallest and lighest generator possible.   But at the same time I don't wanna spend a lot of $$$.Any suggestions?   Is it a stupid plan?
Reply:Probably not the best idea in the world.  In terms of output power the MM135 isn't all that efficient.  A small motorized stick welder might be a better choice, but you have what you have, so there it is.  Any cheap 4500-5500W (Coleman, Dayton, etc.) generator would probably be the easiest route.  They're loud as hell and not very durable, but should work in a pinch.  The MM135 is a transformer based unit rather than an inverter and as such, I don't think it's prone to suffer from power quality issues.  If you intend to use extension cords of any significant length, then get use 12ga.-Heath
Reply:To answer your question, I have run a MM135 off of a 4kw Dayton Generator, running on propane.  Runs it without breaking a sweat.  Just for sake of argument, my genset is 4.4kw peak, 4kw cont.
Reply:A portable O/A rig might be a better choice for the backwoods
Reply:There are also those welders that are specifically meant to be both compact and portable...readywelder and zena are two that spring to mind.  Just other options to consider.Smithboy...if it ain't broke, you ain't tryin'.
Reply:Thanks for the input guys.  I was in fact looking at that setup from Zena.    I'm tempted there.  I suppose that until I get 'need' for a generator, outside of just using it for offroad wheeling trips, it doesn't make sense to buy one solely for that purpose.   I was just hoping to make use of what I already have.

Reply:Best bet for trail repairs is an on-board welder. They have fluxcore mig, and a stick welder version. Cost from $300-500. Uses batteries. Weld up to 3/16 on mig with 1 battery, up to 5/16-3/8 on 2-3 batteries. Awesome tool for trail work.

I used one on my truck after a  incident my son put my truck through in the desert last year. Mig welded stainless uniball adapter to my forged spindle. I never re-welded it, and ran the Baja 1000 with it last year, as is. It WORKS!!!!!
