How are yall doing, I have a weld pack 120 with no gas, i started weleing about a year ago when i couldnt get any exhaust work done in time for a race so I just bought a welder, now here is my question to get a nice bead with my unit what would be the best technique? I am enrolled in a welding degree program at my communitie college but we have not gotten to mig yet. I can lay down a nice bead with oxy fuel i mean i would hump it if i could do the same thing with my mig unit. I try to keep moving the gun and keep the puddle rotating but it seems like it just doenst have the same result, Then a guy told me that i could hit then stop the n hit and stop, i tried this method and the weld looks alot better but im scared that im not getting enough penetration with this meathod any suggestioins would be greatlly apprecaited thanks

 

knowone can help me out

 

someone please help me out with this

 

I would have gotten a gas unit.

Why? Im sure that dosent help AT ALL...


Repetead tacks are how i weld in body pannels. Its good for lightgauge sheet metal and where the amount of heat needs to be kept to a minimum. Im not familliar with flux core welders, ill try and do my best though.

Which position are you trying to weld where you need a nice bead? Flat, vertical, horizontal, overhead, or pipe?

If its just flat which i assume, do a backhand technique (where you push the gun instead of drag along) and to set up you wire speed and voltage (if its even adjustable) you want say set your voltage 3/4. Then set your wire speed half. And get some scrap, and just start welding keeping a 1/4" arc gap. Listen to how it sounds, i know you cant really hear me but you want a steady humming sound, not poping, if it starts jumping or poping, your arc gap is too big and/or your wire speed too much for the voltage. Adjust acordingly. If your not getting a bead, kind just bits and pieces of welds here and there your settings are too low for the material and or your moving too quickly.

Threse's so much to explain! Once you start the welding course you will get the hang of it in no time.

People often look at my welds and think there robotic because they are so consistant.

 

dude i weld on 1/8 inch steel and like my teacher says...position it at a 15 degree angle from the top and draw little circles with it from left to right like when you write on paper.

a gas shielded weld is much better than fluxcore junk.

Its more costly. Money dosent grow on tree's around here. For a hobbiest a fluxcore will do perfectly fine.

 

thanks for all of the input guys ill post up some pics of my welding soon

The amount of money you spend having to re-weld crap could have been used to get a gas unit and you would have saved yourself a lot of time.

 

flux core works great and it penetrates better than MIG. It just doesn't look that hot and it's a pain to see your work with all the smoke. It's perfect for welding outside where shielding gas may be blown away. If you have to re-weld stuff don't blame your equipment.
