So I have a Lincoln hd 3200 mig that hasn't been used in a year or so.. I went and got a bottle filled last week argon co2 mix using solid .025 wire with the correct brand new tip welded on brand new steel tried the l/min from very low to very high always welds the same. I can here gas exiting the gun ground is clean here is a photo of what im working with.. The welds are very black be a wire brush on a die grinder makes a pass over them..
The top weld is c 5 settting what it recommends bottom is b5 (IMG:http://www.914world.com/bbs2/uploads_offsite/img.photobucket.com-9738-1387250279.1.jpg) |

Start at beginning. Did the welder work fine when last used? Did you last use it with gas or flux core? If gas it should still be set right with + to gun & - to ground/work clamp. Did anyone borrow it? Whether you have a flow meter or regulator shouldn't matter as long as it is in good working order. It does look like a gas issue. Did you try to weld on another pc. of steel with the same results? When you turn on the bottle it shows the tank has pressure & the low side gauge should be set at about 15-20 cfh. Gotta run I'll check back with more help.
