they're rows of separate blobs. I'm practicing MIG welding with my new Lincoln 140-C on 22 ga steel. Specs are as follows: ArCo2 mix @ 20 ft3/hr, ws = 1, Volts = D (as recommended by the table), wire is 0.025", polarity is correct and I cut the wire at 3/8" from the nozzle. I'm getting the sizzling bacon sound, with an intermittent "pop". What might I be doing wrong? Am I holding the nozzle too close/ too far from the puddle? Thanks in advance.
seems like your wire is hanging up. i had a spool that was wound all ****y and it kept hanging up and doing the same thing. and try a little more heat
more heat like stated. it should crown in the middle with a little dimple when tacking pieces together. the edge should be near flush with the metal.
Also looks like you have porosity in the welds either you need to turn up the gas or hold the torch a little closer. Look at your welds and see all the little pin holes that's one way to tell if you have porosity in them. Hope this helps Mike
wire speed at 1? that does not seem right to me. try turning up the wire speed and see if that helps.
aint gettin no gas, hold the nozzle next to your ear and pull the trigger listen/feel if there is gas coming out the tip...if not trace the line back to the tank and find out where the gas is goin
Slow down,watch the puddle, not the wire.. More heat,slow the wire feed a little, slow the process down,for max. penetration.
Learn to weld on thicker metal, about 1/4" or 1/2" metal. its much easier to learn on that then move to thinner stuff. Definitly way to cold. The welds are just balling up on the metal. as for pressure i normally run at about 13 psi. with the tank cracked way open, and use a 75/25 mix of argon/carbon dioxide. If your still having trouble go to your local welding shop. they can normally help you out if you bring in your welds.
a couple things that i have found is that table on the inside doesnt really help,definitly turn up the wire speed,also make sure you incoming power it good and you are not using an extension cord.you can use a cord if need be but make sure its at least #10 not more than 50 foot long.also check to make sure the polarity on the machine is correct most units come set up for flux core wire wich welds with a different polarity(at least on my hobart)22 gauge is definitly a challenge but 025 is a good choice for wire.hope i helped good luck!
well your wire speed = your amps and at w/s 1 your not putting anything into the metal. it also looks like the wire is melting before hitting the metal causing it to just drip on to the metal you want to wels .turn up your w/s turn down your gas to about 12-15 unless your welding out side and you want to be anywhere from about 3/8 to 3/4 from the cup to the metal
Look at your polarity. Most migs are setup to function as a gasless wire welder, and a mig. When converting back and forth you have to switch leads inside the welder, probably next to the wire spool. Also verify you're using MIG wire instead of rosin core for gasless wire-feed. As mentioned, listen for gas flow. Also watch 2 feet of wire run out of the welder and make sure the wire moves evenly and smoothly. Good Luck!
Bingo! When I swapped fluxcore for MIG wire, I didn't fully reseat the weld gun hose and when I squeezed the trigger, gas leaked out at the wire drive. I was too focused on the puddle, wire feed and "sizzling bacon sound" to notice... and only discovered my stupidity when feeling for gas flow at the nozzle as hotrodbrad suggested. After that I spent the evening experimenting with wire speed and voltage to make bigger & smaller beads. Thanks for all your suggestions, everyone!
always remember - the metal can sense your fear dont be scared to "get on the weld" and get good penetration
be sure to notice now how the welds pulled(bent) your panel and keep that in mind when you're working on your project.
On the mig I'm using you really have to bottom the trigger out to get gas... Took me a couple of WTF moments to figure that one out.
I would practice on 16 and 18 guage as that is what old cars consist of. Never run a continuous bead or you will warp the panel. Practice tacks. In and out in a fraction of a second.Hit it with the air hose. Never let that panel get hot or it will warp. Practice **** welds. Soon you will be shaving door handles and doing all kinds of cool **** you never thought you could. Good Luck
