Rated 1 out of 5 by from can not increase wire speed manually Bought this with a Syncrowave 210... can not get the wire speed to increase... by looking at these other comments... looks like similar problem.... I teach welding at a college... bought four,,,, have request in for 16 more syncrowave 210.... will revise this and talk to local Miller rep to find a machine and spool gun with wire speed in handle of spool guy.... Welders are not ignorant.... we can still use machines that have manual control knobs on outside of machine,,,, and on the spool gun.... computer menu is not better than manual setting knobs... just my opinion.. :)

Rated 1 out of 5 by from ABSOLUTE GARBAGE!!! I had this for 3 months and struggled to do any nice welds with it. It got too hot too quick and the wire feed could not keep up. I always had the wire feed up quite high which caused the motor to burn out quickly. I ended up buying a spoolmate 150 instead and was very happy with it after 2 years. The 150 is a much better unit. If you need to weld aluminum the 100 gun is not really an option.

Rated 1 out of 5 by from good gun weight wise bought this gun a year age not the best investment it birdnest , burn back's to often , no room feed wire in rollers have to remove a roller to do this and the hold down is to hard to hold and feed wire through both roller and into liner , spend more time fixing gun than welding ,, never again will buy this !!!

Rated 5 out of 5 by from Preheat is a must Great gun and will work even better when you preheat aluminum, Preheat will allow the wire to penetrate deep and produce a pleasing weld bead. I have used the spoolmate for rebuilding damaged power sport engine cases.

Rated 3 out of 5 by from needs a redesighn this was purchased with a 211 autoset to be able to mig aluminum. when first set up we only had 120v generator power.the gun was loaded with .030 alum. wire 100% argon. it welded second time, a little tweaking of the settings and it was making good looking welds. I had now discovered that the Miller 211 is not auto set with the 100 spool gun. ( to be fair miller never actually says the 211 is autoset when the 100 is used, and does say it is not, BUT this is buried deep in the instructions). next I moved to a location that had 220V house current set the machine to recommended settings, pulled the trigger and the wire immediately burned back into the tip and birdsnested. settings were adjusted and two more tips were plugged with resulting birdsnests. now I am learning what a pain it is to change a plugged tip , clear a birdsnest and rethread the gun. getting wire into the drive rollers and fed into the liner is at best a three hand job. the trenched release leaver should have a lock open catch so both hands can guide the wire through the drive rollers and into the liner. a pair of small needle nose pliers and some dental picks should come as needed accessories. The gun welds very well and I have not yet burned another tip. I do wish this spool gun were adaptable to other Miller welders like the trailblazer and suitcase.

Rated 2 out of 5 by from Tensioner needs to be able to get totally loose for the correct amount of pressure on the rollers gets applied I tryed welding with 4043 aluminum and it was a bad idea, the rollers are not adjusting enough to feed the wire without crushing it, many times i got a bird nest because the wire got stuck after the rollers and before the liner, i was able to hear the noise of the liner and of course i had a nightmear with tips. I used .035 wire and tryed all kinds of things to make it work. I changed to 5356 wire and dissasembled the gun to see what the problem was, found out that there is not enough space to correctly guide the wire to the front of the rollers and i know now that this design could have been better if you just stop and think that whomever is going to use has bigger hands and fingers. I hope this helps, really, too pricey, make it better.
