Mig welders got a question.
Mig welders got a question. At work we have a Miller 210 mig welder. My question is what is the best way to weld side to side or in a straight dragging motion? Thanks I'm a newbie at this mig welding?
I am thinking about picking up a welder at work and learning(Assistant Manager at Harbor Freight). I could get a 110v Mig welder with a roll of wire, mask, pliers, etc, for less than a hundred bucks. The haynes welding manual is freakin awesome. They seem to think that a 110v mig welder is okay for a seldom/beginner welder. What do yall think?

There has been a lot of discussion about pushing vs. pulling the weld pool.
There are several schools of thought:
1st: If you're using flux core, the shielded field comes right off the wire, so direction is only important in depth of penetration.
2nd: You should always pull the pool. It's the only right way to do it, if you're ever in a weld shop everyone there only pulls, unless you are going vertically.
3rd: You should always push the pool. This way the gas field goes ahead of the wire and you are welding in the shielded area.
I'm not calling anybody out. Most people know more about welding than I do. I'm just looking for a little more discussion.

Personally, I normally push when mig welding. You are "pushing" the heat and the gas into the base metal. I actually do a little circle motion with the gun to get a nice looking bead.
When migging aluminum, you pretty much always push to optimize the shielding gases effect.

I have a HF welder. Its a gasless MIG 90. Welds like crap. Arc wont stay lit on it.
I now have a Lincoln Pro MIG 140. I have not bought the gas for it yet but it welds nice as heck with the flux wire. Its rated to weld up tp 5/16" material. Thats thicker than anything I will ever weld.

I have:
Lincoln 110 mig [135]
Lincoln 250 mig
Lincoln tig 250
Of all the machines, I use the 110 for 90+% of my projects.
The tig is used for "trik welds", such as fuel tanks, rollbars, small brkts, etc.

Had a Century 90 amp for years. It worked for most everything I did. I mostly used it for small fabbing and repair projects. Found out real quick that it was not enough for a mild steel roll bar so I bought a Hobart 140 (110 V) Weld tenique for me is the same though. Always looking good penatration on a structural piece, so I'll push the weld in this case. I'm a bit lazy when it comes to reaching over and changing settings, so when I come to a thinner material I will pull the weld at a bit faster pace so I wont blow through the material. It works for me.

well theres a lot of discussion on this, but "most" on the welding forums agree that pulling will yield more penetration. if you lay the gun back too much with the "push and circle", on your backstroke youre just heating the filler that you just put there. but, when you pull, your essentially heating the metal under the filler you just laid and pushing it under.
some will argue that you preheat with a push, but i would rather continue to push the metal into an already cherry area like with the pull.
