Longevity WeldMax LC-416D Review and Comments
I ordered the above machine from Simon at Longevity over the phone while working a boiler outage. I decided to order the machine from Longevity after trying out a similar machine from another company. The other companies machine I tried worked fine however I chose to purchase from Longevity. I will document some of my experiences with the machine.
4/23/09 The machine came in well packaged. No Manual.
6/13/09 I haven't had much time to use the machine but had to throw together a jig to do some guided bend tests. I used the Plasma Cutter to cut some 1/2" plate. With the amperage all the way up the 1/2" cut was difficult. I cut about 30" altogether and it took two ends of one electrode. Didn't have time to figure out the problem and the cuts were pretty rough. The digital readout on the dial showed 33. The amperage knob did not go all the way to the maximum reading on the dial. After the cutting was done I welded 2 pcs of 1 1/2" round stock to the plates. I left the machine turned all the way up (150 amps) to see if I was getting full amperage. It did not appear I was as 150 amps should have seemed a bit high for a 1/8" 7018. Below are some of the welds made. The machine welded VERY well. The arc was stable and never cut out. Slag peeled off by itself on the horizontal fillets. I Welded flat, overhead, and vertical welds and the machine performed well.
6/18/09 I had a little project I wanted to make for my daughter. The plasma cutter worked fine on the 1/8" flat bar I used to cut the notes from. I did notice quite a few times in which the arc would not strike. Spoke to Simon and he gave me some things to look for but I haven't opened it up yet to look. Below is a picture of what I did.
19 October 09 It has been a slow summer and I haven't had much opportunity to review the machine. I used the machine for a few short cutting jobs and had some issues with getting an arc started. This seems to have been caused by air pressure too high. I was told to reduce the pressure to 65 PSI. I have done that and arc starting seems better but 1/2" capacity as done by the Everlast machine seems hard to obtain. I have to do some more testing. 27 January 2010 I recently loaned my machine to one of my students to practice for a welding test. He has absolutely no prejudice to any company brand. He indicated that he liked the way the 416 stick welded as compared to the Miller XMT 350 he used during school. I thought that was interesting. HGe said the arc was smoother. The machine is being used for GTAW root passes and 3/32" fill and cap on 6G tube coupons similar to the Boilermakers Commonarc test.
