  • Lincoln IdealArc Tig-300/300 Question

    For tig welding:

    Guys, I've got the above welder and have a question regarding the two cables on the machine and exactly how to bolt them on. One is larger diameter than the other and goes to a large spring clamp that is attached to my welding table, Does that cable bolt on to bolt labeled "ELECTRODE" or to the bolt labeled "TO WORK". The other cable is narrower in diameter and goes to the torch "stinger", does it bolt to the bolt labeled "ELECTRODE" or to the bolt labeled "TO WORK"?

    Electrode to the torch. Work to the work or in this case your table.

      I Agree....

      The "Work" terminal is sometimes called the "Ground" connection....

      You may want to download the manual....here

      http://www.lincolnelectric.com/en-us...r-manuals.aspx

      it should answer most of your hookup and operations questions...

      There should be a "Code or Stock Number" on the welder data plate that will correspond to the correct manual

        Thanks for response Guys, I do have the original manual, however someone told me the exact opposite and I just wanted to make sure, I'm having a heck of a time with my welder and have it all set up as the manual says just can't get it to weld. It just burns up the electrodes (tungsten) and I can't get a puddle. just trying to eliminate things before I haul it somewhere for a look-see, closest place is 85 miles one way not to say having to load it up on my trailer with winter coming on.

          can you post the "Code Number" so we can look at the manual too...??

          BTW...where are you located....??

              The code number is 7723-c
              I am located in Lincoln, Montana on hwy 200 midway between Helena and Missoula
              The machine is one of the grey rectangle shaped ones.

                This would be your manual

                http://www.lincolnelectric.com/asset...oln3/im265.pdf

                Are you sure that you are set DC Electrode Negative for steel...??

                100% ARGON gas..???

                switches set to REMOTE....

                Pedal....???

                FWIW...... IMHO..... Linc's of the "Grey Era" were their best....

                  If you're burning up your electrode, probably have it hooked up EP. Tig welding is EN.

                    Here are my settings:

                    1. The pointer is set at DC- (straight)
                    2. Fine adjustment current control is set at "5"
                    3. Remote control switch is set at (remote Control)
                    4. Afterflow timer is set at (1/8)
                    5. solft start switch is set at (on)
                    6. It is set at (inert Gas welding)
                    7. Spark switch is set at (On)
                    8. Spark intensity knob is set at (5)
                    7. Current range selector is set at (Medium)

                    I have a foot pedal hooked up
                    I have a air cooled torch (stinger) I am not using the water hookups for the torch since it is a air cooled torch.
                    The welder is not grounded.
                    I am using 100% argon gas

                    What is EP and EN

                      EP is Electrode Positive + ................. EN is Electrode Negative ( -)

                        Do not know your experince level

                        might be operator related.............low gas flow rate CFH.... or excessive arc length ....or...???

                        could be worthwhile to review TIG guidelines

                          Setting your machine up for tig welding EP will make you sad....all of those other settings listed notwithstanding.

                            Thanks to all that responded, my experience is not that great. I welded very well years ago in Gunsmith school, but haven't done any in 15 years plus. I'm just starting to get back into it.

                            So I assume I need EN. How do I go about that?

                            I'm welding small parts. Once set correctly and or fixed I plan on practicing, practicing, practicing until I get right and am ready to go. I welded really well years ago, surely it won't take as long to get back to where I was as it did back then..............I'll get it right as soon as I determine whether it is me or the machine. I'm just trying to rule out whether it is the machine first. If I have to I'll haul it down to a Company that can determine that and while they're at it they can go through it and do a service.

                              I'm not familiar with your machine. A lot of machines you just swap the leads around. But since you say yours has "work" and "electrode" labels on your hookups, my guess is you have a polarity selector lever of some sort. My old Helga has that. Makes sure it's set to DCEN, also called DC straight.
