My wife bought me a HH175 as a surprise. I am new to welding and my technique needs improving so I need to use a grinder "A LOT" to clean up my welds. They aren't pretty but they hold up to the hammer test. I use a 4.5 inch 8amp Dewalt grinder to clean up now and it does a good job but it lacks power. Do any of you use a 7 inch grinder to grind off the metal or make cuts through steel? Or are those 7 inch monsters too unwieldy? Thanks in advance for any comments.

I have a 7 inch I use when I have ALOT of material to remove. Its's a cheapy from Menards. I believe it was less than 45 dollars. I also have a 4.5 Hitachi and a 4 inch older one I have retired to a wire brush. The 7 inch is heavy and powerfull enough to remove large amounts of metal in a hurry. But its to large and heavy to use for the general light stuff you will do.

Green,
I have both , but almost never use the 7" for the home shop as a disc grinder. Mainly use the 7" machine with a cup wire brush for cleaning.
The 4.5" grinder seems to be much more less tiring to use and safer in that it is lighter and easier to control.
I have worked in heavy industry for many years and the large disc grinders are used for mainly heavy work.
An electric die grinder also works well for removing bad welds.
As far as power goes for the 4.5" , my Milwaukee also pulls 4.5amp and seems plenty powerful.
Good Luck and don't forget that face shield when grinding. ( I speak from experience ! )

I have three; 7" Milwaukee, 5" DeWalt and 4" Makita. If you default to the 4-1/2", get a tough one. My choice for 1 grinder would be a 5", either barrel grip or handle style. This is mine:Comment

Welcome to the forum Green. I see you are from Wacousta...I am in Grand Ledge...about 5 miles away. I also have a HH175. Fire off an email if you need any help getting started with the new welder.

Welcome,
I tried the Metabo's at the welding show, excellent grinders. You may want to consider their excaliber 6" unit. light weight and very smooth. It had a great feature of a soft (slow) start and then maintained a proper speed depending on pressure applied. It seemed to me that you could use it all day and not get fatigued from the vibration. Price is about $210
Good Luck

Grinders
I have a 4 1/2" for my wire and a 4" air grinder for steel. I love my air grinder. It is hard to load it down, and it has been going strong for 2 years now. When I have to get another one I am going to go air. Just my 2 cents worth, SandmanComment

I have a mess of grinders, Hilti 7", two Hilti 5", and at home I have a B&D 4 1/2" (with bearings making more noise than the grinding) and a deWalt similar to the B&D, noise and all and a powerful 5" Milwaukee, which is impressive. I spent all morning looking at Metabo grinders. I like the W14-125 ergo model. 169 here in the States, and some 394 in Austrailia...quite a jump!
I'll look up the address where I saw it.....
Here it is:

Rocky,
When I went to the site you stated I found the W14-125 to have variable speed, but when I went to www.metabo.com the W14-125 was listed as a constant 10,000 rpm. I don't know if you were interested in the variable speed or not, but there does seem to be a difference between the two sites. I'm looking at a grinder update, and found that milwaukee has a nice 12amp, 5" model, with variable speed, constant under load--but I don't like the paddle switch. Makita has something similar, but has a side mounted thumb switch--which I like better. But the W14-125 has similar features to the above (if we believe the website which shows variable speed)--yet has the best switch position of them all....in the rear. I guess I'll have to look into this further to see which of the websites is telling the truth.
