My Test & practice welds.

admin

Ok. Got my Hobart 140 unboxed, new Striker CSV helmet on, flux-core wire in for some warm up practice. WireWelder HelmetFirst weldsThis was an attempt with 18 gauge and flux core. Yeah that's not happening. I'll go get some .023 wire and hook up the tank

Reply:So what did I do wrong or right?And advice with flux-core?  It's nothing like I remember regular MIG. I finally was seeing a puddle. I did better when I was working north-south direction. I couldn't see anything left-right movement, so I tried pulling it towards my body seemed to work better. The voltage was on "2" setting and wire was little under 30Last edited by randomBullets; 09-27-2014 at 11:01 PM.

Reply:How are you liking that striker helmet ? I was debating buying one but I have my heart set on a miller titanium 9400. Are you pushing or pulling the weld bead ? Keep practicing and if you're going to weld a project with flux core make sure to pick up some spatter spray and apply a light coat to the metal so you don't get all that spatter sticking all over your project.
Reply:It's hard to compare a 110v welder to a "traditional" Mig welder. They really don't look too bad for 0.030 Flux core. You're going to get a lot of spatter with that stuff. As far as direction of welding, I try to get people to avoid welding toward or away from your body. So much is muscle memory and rarely will you be able to get a weldment set up straight toward or away. You may need to move your body and your head to peek from the side. Also fcaw should be "pulled" like smaw not "pushed" like Mig.Teach Ag Mech - Mike At Home:Lincoln Electric AC225Miller Challenger 172Gas AxeWork:eclectic bunch of 90's vintage blue boxes

Reply:Is the machine polarity set up for flux core or mig?Your negative lead should be hooked to the gun and the positive to the work lead.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum
Reply:It's set for flux-core. I did manage to remember to check that. Luckily it's set that way from the factory.
Reply:That's an excessively high level of spatter from a Hobart self-shielded fluxcore wire with a Handler 140. I am suspecting you didn't have the unit dialed in very well. Dialed in correctly you should experience a smooth consistent open arc metal transfer that produces a very light spatter level.ESAB Migmaster 250 Hobart Ironman 230Multimatic 215TWECO Fabricator 181i & 211iHH125EZ - nice little fluxcore only unitMaxstar 150 STH - very nice

Reply:O.k.  I'll try it.
Reply:How much stick out are you running? With T-11 wire you can generally get away with murder for stick out. I like 3/8 to 1/2-inch with T-11 wire.

Reply:I'm only running like 1/4" stick out. I'll start with more. And your welds look very nice. It also looks as though I need to make bigger motion while welding

Reply:Looks like you were maybe holding too long of a stick out and your wire speed is incorrect. If I were you I would start with plain wire and gas first. Fewer variable to control for. Also if you bought that welder new, then it comes set up for gas not flux core. I know you said you checked the polarity but I would urge you to check again, since I suspect it is still wrong.Miller Multimatic 255
