Hobart 175 vs. MillerMatic 175

That's what I was thinking, with all the comments about having a tapped vs. non-tapped switch. Are the non-tapped controls so inaccurate that you cannot rely on the #'s on the machine as an accurate guide? I hope this isn't the case, on the other hand I understand how non-tapped can be overwheling for a newbie, but now that Dan has pointed this out to me I'll besure to keep the voltage control set on the big numbers and fine tune with wire speed...

Does this sound okay (if I get the MM175 vs HH175)?

Thanks!

The voltage control on the MM 175 just has a 1-10 number systyem on it. The higher the number the higher the output voltage will be for a given wire speed setting. Lincoln use letters A-J on there voltage control. The only way you know the load voltage on these machines is by having some one measure it for you while you are welding. This is also true for the tapped voltage selection machines like the HH 175 or lincolns 175T

I understand, Dan. But what I'm really asking is if the knob on these variable machines can produce consistant results if you put the knob back on the same settings. It sounds like being able to reproduce the correct settings is key to consistent results as you change the setup from one thickness to another.

I stopped by my brother's shop today (auto body tech) and he showed me the welder they used on those fancy mercedes he works on. I was surprised to see it had taps! one for the main voltage settings and one for fine tuning.. the fine tuning knob had 5 settings of it's own, while the main one had 6.

Now I think this is the best of both worlds as it allows some fine tuning, but not enough to drive a novice like myself crazy!

Now I'm leaning back towards the HH175, but the better construction of the wire feed system on the MM175 are calling out to me! Where I am the price delta is only ~$60..

Thanks everyone, I'm learning a lot!

Infinate voltage control is accurate as taped controls when setting to chart. Bigger difference between chart and your settings that should be consistant so you use fudge factor for your settings or for wire not supported by chart. Fudge factor is just up/down a letter or number on speed scale or so.

The voltage and wire speed setting will stay pretty consistent for a material thickness as long as your input voltage to the machine remains close to the same value. For example, if you use the machine at your place and your input voltage is around 240 volts. Then you take the machine to your friends house to use and his input voltage is only 220 volt you will more then likely need to increase your voltage and wire speed settings at the friends house because of his lower input voltage.

Zyvek, I thought it important to mention that tapped machines do have a fine adjustment - wire speed. Say for instance you are running in tap #3. Increasing wire speed will increase heat and vice versa.

Me being a gear head, I went with the MM175.The Blue makes it looks faster. ....Jay

Well I found a HH 175 for $503!! at one local shop and at another shop the MM with a free cart for $599!! So i'm still torn, but with the free cart I'm pretty sure I'll be sitting pretty with a MM by the end of the week!

Thanks everyone!

Rock! Keep up the great work on this message board ! Hey I own some riverfront property in Oconto Falls, WI. How close is that to Hobart?
