Hey Guys; A few days ago I asked you about the B 300Q and appreciate your responses. One other question about it, is fixed neck or rotatable. All I've ever used is fixed,and some say that's best.Is rotatable as reliable or necessary? Again your expertise will help.
Reply:I have a flex neck gun, and it's OK. If I was buying again, I wouldn't bother with it. I use rotatable neck Binzels at work and like the feature. I haven't used the Bernards, but I will comment on what I like and dislike about the Binzels I'm used to.I like he ability to put the gun in a more comfortable position relative to my wrist. I'm right handed, and I typically rotate the neck about 30° to the left for most welding. With my natural wrist position relative to the weld joint, this gives me a slight drag angle on the puddle (most of what I burn is gas shielded flux core). If I am having to switch between right and left handed operation, I leave the neck inline with the trigger. Occasionally I find myself welding something where I am most comfortable with the trigger on the back of the gun, operated by my thumb. We have two styles of guns, tooless (Alpha models), and those requiring tools (Omega models). I prefer the Omega models which require a 4mm allen wrench because I feel they are more durable. On the toolless models, the base of the neck has a large screw collar that locks the neck into position. This screw collar is metal with hard plastic molded over top to grip it by and to insulate it. With time the plastic cracks, becomes loose on the metal collar, and eventually breaks off entirely. The bad part about this is that the metal collar is in direct contact with the brass mating surfaces where the neck meets the rest of the gun, and is therefore electrically hot. Like I said, this downfall pertains to Binzel guns, and just the toolless rotatable ones. I am unfamiliar with Bernards, and do not know how their rotatable necks work. If I was in the market for a new gun, I would choose a rotatable neck. My thoughts are pass on the flex neck. What little extra versatility they offer is offset by the fact that you have to be more gentle with them.
Reply:You can get the Bernard QGun with either the fixed or rotatable neck and both cost the same when you order the gun new from Bernard, as far as I know. All the Ebay Q300's I have seen have had the rotatable necks as far as I could tell from the pics.I have 4 QGuns and they're all rotatable neck models. The rotatable neck is well worth it, I use it alot on the guns on the Passport and Suitcase migs on the truck as I can get to awkward joint positions easier with the adjustable neck. I don't use the adjustable feature nearly as much on the shop machines. It is very easy to use and requires no tools, just loosen the collar by hand, rotate the neck to desired position, tighten up the collar, takes only 5, or maybe 10 seconds, to accomplish, if you do it slowly. You can get different length and angle of necks for the QGuns too. I like the short and medium 45 degree bends for general use and the 60 degree bend for going around pipe. The longer neck lengths are good for running hot as they keep the hand further away from the arc.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op |
