    Question Milermatic 135 question

    I am begining to build an enclosed ATV trailer and I have a Milermatic 135 and use with flux core wire (too windy and no garage). Some people are telling me the 135 is not strong enough to weld 3/16 channel and angle. Any thoughts? I am having the tongue welded at a trailer shop that has a monster mig welder so I am not worried about that part.

    The 135 should be fine for 3/16 with flux-core. Ive welded up to 1/4 with it. Now that i have a 251 i can see how limited the 135 was though. And for the coupler, just bolt it on.

    3/16 i think would be pushing the limits of that machine my opionion!!!! you could tapper the edges and making two passes

    I welded some racks that were 1/4'' mild steel with a 75/25 mix with my 135 (single pass) and the racks are holding 3 tonnes each. I did taper the channel though before i welded it.

    Thanks for the response! The heavy welds will be done at the trailer shop.

    3/16 with flux core is definitely within the limits of that machine. With proper care, 1/4 may be possible. I have done a lot of 3/16 with mine. Now anything over 1/8 with solid wire is definitely pushing it. It will give a cold 1/8" weld at best, but it will barely do it. If you have good single pass 1/4's, then you got very lucky since the recommended range (according to the Miller calculator) for 1/4" steel starts at 180 amps....way more than the 135 can put out.


    One key to getting good output with the 135's is the power input. They need to be on a dedicated circuit. If you must use an extension cord, use a heavy one and keep it as short as possible.

    I have a 30 amp circuit just for my 135. Before when i ran it off a 15 amp circuit i was always tripping the breaker. It was spattering all the time and the welds seemed cold.

    as the picture states, you can go a little more than 1/8" , with flux core wire, and, maybe a few multiple passes , for the thicker you might wanna stick weld it,
