Its a Hobart Handler 140, seems to be pretty easy to use, i have only welded a few times and im picking up on it pretty quick, i thought it would be something i could use for a long time and a nice skill to have, if u guys have any tips feel free, im always up for learning from the best thanks guys!

 

What about welding without the gas? i just ran a bead and noticed that it pops alot more and i get alot of splatter, is this from not using gas?

Running the fluxcore wire (no gas wire) will cause splatter....but it really isn't that bad when you start to get a hang of it and use enough heat but yes there will be splatter.

You should practice on thick pieces of steel then you can learn how to go slow and build up a puddle in the metal. The start up of the puddle is the most important as if you don't have enough heat you won't have a good puddle.

The poping can sometimes be cause when your heat range and wire speed isn't set right. If the heat range is too low and your wire speed is to fast then you are trying to feed the wire into a puddle that is cooling off too fast the result is the wire is bouncing off the cooing puddle instead of melting into it. This will usually cause the "pop pop pop pop" sound as the wire arcs on and off the cooling puddle.

If everything is set right it will sound like you are frying bacon....sizzzzzzzz...alot of bacon

It's called spatter.

cool man that was really helpfull, now i just need to find out what to put my senttings on, im just welding like exhaust pipe (well enything steel that i can find layin around) together and just running beads on it, my welder is the hobart handler 140 wire speed set at 40 and heat on setting 2, it goes from purge,1,2,3,4. Oh and i put it on purge just to try a bead and it wouldn't do anything i need help haha im such a n00b to this ****...

 

Yeah sorry I'm not familiar with that model, they all basically operate the same but even the same machine will end up with diff settings sometimes.

Yeah Exhaust pipe is pretty tricky to learn to weld on with the gasless or when you are starting out (you're using no gas right?).

Purge sounds like it is for when you have gas hooked up....but I dunno

 

oh ok man, thanks! yea it is setup for gas but i havent bought the tank yet. So im just using flux core right now.

The purge is exactly what u said it doesnt feed any wire it just purges the gas through the line as does nitrous, to make sure u are gettin gas into it, haha i friend told me all that so now i understand it alot better.

But thanks again for all your help.

 

hey, talking from expercence, when you migging some exhaust piping leave a very small gap between the 2 pipes then do a zig-zag pattern kinda like /\/\/\/\/\/\/\/ and that way you will get good penatration with a pritty flat weld and it looks good too our autobody teacher taught me that becasue that the way they weld 16ga steel

 

yea a few buddies around here told me the same thing, i appreciate all the help, thanks guys!
