I have a Northern Industrial Mig/Stick 200 in my service truck, and a late 90's Miller Bobcat 250.

For the most part I do stick welding at work (Field service tech for a concrete paving company), but there are more times than I care to think about that I have to weld in confined areas where you can't get a stick in the hole, get the angle and movement that you need, or flat lack of skills stick welding metal less than 1/8" without burning through (my welder is bitchy and does not like to stick weld at low amps with the 3/32 rods).

Since I am in the field, gas welding is out, it always seems to be windy when I choose to weld, so flux core for me.

I take the NI MIG ground clamp, connect it to the stick torch port and clamp that to my Miller torch. The Miller ground to the work, and get a guesstimate setting on the welder (welding selector ~ Low wire/Hi wire and dial the amperage in) and go at it. 35 feet from my truck and all I have control over is the wire speed, but I have a good feel for the settings now after a little practice.

Kind of a drag running 3 cables, but the end result is worth it. No more hitting the duty cycle with only another minute of welding to go.

Double bonus, I can now MIG up to 3/4" thick now rather than the 5/16" it's rated for at a pale 30% duty cycle.

I've done a couple of fabrication projects off my bumper and I am real pleased with the results.

On a whim, using Lincoln .035 wire, and the Miller maxed out, my wire feed can not feed fast enough. Really wide spray pattern, but good penetration. I'll try to post some pics of some sample welds this weekend.

FWIW - Everlast and other import companies really need to get on board with suitcase MIG welders for these applications. I still can't grasp why the name brand suitcase units are $1700 plus. If you are running an older gas welder, you still don't have control over the amperage, only wire speed.
