Mig Flux Core
Saturday, June 12th, 2010Mig Flux Core

The Hobart Trek 180 is a portable battery powered Mig Welder. The only one ever made that has enough sack to weld 3/8" thick steel.
I had a chance to do a review on a Hobart Trek 180 mig machine and I really put it thru the ringer. Most Welding Machine reviews I have read only go so far as running a bead or two. I did that too, but I took it a step further...
I actually welded an AWS standard bend test with it! But did it pass?
The Hobart Trek 180 is capable of running either.024" --.035" bare wire or.030" or.035" flux core Welding Wire.
The bend test I did was with the smaller.024" diameter ER70S-6 bare wire and 75/25 argon/CO2 shielding gas.
The test metal was 3/8" thick and was welded in the vertical position. The root pass was welded downhill and the rest of the welding passes were done uphill.
Halfway thru the last pass the low battery light came on and the machine quit welding. So I plugged in into a 115v 20 amp breaker, let it charge for about 20 minutes and finished the weld.
Then I cut 2 bend straps out of the plate, ground the weld smooth and bend the straps 180 degrees on the weld. One root bend and one face bend were tested.
The results? A little indication on the side of one of the straps indicated a bit of sidewall lack of fusion but other than that...
It passed the bend test.

Which is better, flux Core Wire fed Mig Welders or stick mig welders?
I'm trying to decide between these two types of welders to get. I'm only going to be welding Mild Steel (under 1/4 in.) and maybe Sheet Metal and am looking at two 120V input models.
The wire fed welder is rated at 90 AMPs max while the the Stick Welder is rated at 120 AMPs max.
I've done some Stick Welding in the past and have done very well with it. But is the wire fed welder more versatile?
hope this helps you i have used both there are disadvantages to both of them but as far as i am concerned the Wire Welder is the best for the home owner this is why i think you have to keep the rods dry on stick welder the electrodes burn UP very easily if you do a lot of welding you will probably never need the amps that stick welder has any way we had a stick welder when i was growing up and i cut my teeth on one learning how to weld i was pretty good at the heavy stuff of course heavy on a farm like we had was plow sheer or a pair of post hole diggers that need new point s the wire welder needs a lot less maintains it will do any thing that you will need to do the only thing that i would say is get the one that use argon not flux core it looks like it more expensive but if you get right down to it you will get better welds with it then with flux core with a lot less slag then the flux core and you can a little thicker material if you need to You may not need to a buy a brand mane like Lincon or miller there or some out there that are just as good for people like you and me the one i have is Titian it is not made to be used every day but then i am not not use=ing to make a living either it will weld up to 5/16 if you let take it s time it will do ever thing that you want i think let me know what you think douglassmith1957@yahoo.com put ask in the subject line
