Or what nob do you adjust ?   Posted: Fri Nov 21, 2008 2:46 am deecaig Member Joined: 22 Aug 2007 Posts: 43 Used to have a cheap repco mig it had wire speed an amp on the front. _________________ logun gladi8tor .22 walther 1250 dominator .177 crosman 1008 .177 crosman 2240 .22 crosman 2260 .22 several old springers   Posted: Sat Nov 22, 2008 2:56 am Jaxom Senior Member Joined: 06 Aug 2008 Posts: 927 Kanyon, Need a few more details then that before I can give a hand. What are you trying to weld? How thick is it? Are you using flux core or solid wire? What size wire? _________________ .22 2300kt Crosman Custom   Posted: Sat Nov 22, 2008 9:40 am AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6908 Location: "Out There" Technically speaking, a MIG welder does not have an "AMP" control as would an ARC welder. A proper MIG welder will have a wire speed control and an arc voltage control. To raise the amperage significantly, the voltage must be turned up, as well as the speed control. Just cranking the voltage up will raise the amperage somewhat, but due to the old V=IR or I=R/V formulae, the speed control affects this. If your MIG is a lower-end unit, it may not have a separate voltage control, I saw one made-in-China special once that had only a combined speed/voltage knob. For resources on MIG welding look here: http://www.expertvillage.com/video-series/787_mig-welding.htm I have to qualify that and say I've never actually watched those clips, so they may or may not be terribly useful.   Posted: Sun Nov 23, 2008 1:19 am kanyon Silver Status Member Joined: 09 Aug 2008 Posts: 1582 Location: New Zealand AirGunEric wrote: Technically speaking, a MIG welder does not have an "AMP" control as would an ARC welder.

IN short....the more wire thats coming out the more amps it can carry before it melts " WIRE SPEED" The welder in question was a Esab 400amp one of the young guys was setting it up with Co2 sheilded flux core "DW100" and trying to adjust the amps with the volt setting _________________ Career Infinity PCP .22 Webley Patriot .25 Hatsan mod 75 .22 Hatsan mod 99 .177 (Quattro & SAS) Kral underlever .177 ............................................. .
