The 185STW arrived the other day. Most impressive, but with comments/problems. The machine, and package was impressive. Well built, and accessory's are great. Comes with everything you will need including the power plug. Really great.
Poked arround and figured out how to set up for stick, and tried to run
6013. No go. Turns out the "VRD" deal that reduces terminal voltage makes this thing pretty much unusable on stick. And thats a bummer. Fumble farted around tring to get the darn arc started, and finally got it go, and it runs really really smooth on DC, and thats wonderfull. Set it up for AC, and the square wave (at 60 Hz), is not "quite" the same as 60 Hz sine wave of the Miller Thunderbolt, but not to objectionable. But again, next to impossible to start the arc. I finally gave up, and had another seasoned stcik welder try, and he finally gave up, threw down the stinger and said forget it, this would never work out for any kind of reasonable production/repair work. The only way I could get the stick mode to work was to set the thing to TIG mode, and start the arc with HF (using the foot pedal). So if anyone knows what the deal is here, or how to defeat this VRD thing, let me know.The manual is good and bad. Obviously written by engineers. No where in there does it show labels on any of the front panel buttons which is strange. They show the front panel, with lines, but they don't identify all of the LED's and buttions, and on one page, the picture of the front panel doesn't even match the unit itself. Low marks on the manual :(
The TIG side of the house seems great. The HF starting works great, and although I don't know what I'm doing on TIG, the pre/post flow etc all seems somewhat explainable. Having never TIG'd before, I was TIG welding 1/8" mild steel plate in no time.
Only oher question/issue is that I'm getting metal deposits on the edge of my gas lens which seems to build up fairly quick. I was at about 10-15 CFH of 75/25% Ar/Co2, and playing with anywhere between 50-100 Amps with the 1/16", and 3/32" electrode on clean mild steel plate. I think the lens that came with the torch was a "Aluma cup" (?) that had the reduced diameter tip on the lens. Anyone know what I am doing wrong? Played with .040 filler, and 1/6" filler.
The machine seems great, but that stick mode deal is just not working, and I'm hoping there is something that I'm doing wrong. If I can get past that, I think this is a high value deal (overlooking the very weak manual)
Thanks in advance !
