Here is a TIG practice weld that I did on some 1/4 inch mild steel. Not a complete weld, but it demonstrates the quality of the contstant HF. This machine starts an arc with the hand activation on the torch. I did this weld without the foot pedal that came with the machine. I am able to set the current directly on the machine. When I plug in the foot pedal, It takes over the amperage control of the machine. The amperage can be limited with a control knob on the foot pedal.

I have a Longevity WeldAll LS-200PI multi-purpose plasma cutter and welder. Im wondering how I would be able adapt this machine to a cnc machine. The specs say that it is compatible because it is a pilot arc plasma cutter. I would like to know what process I will have to go through to make this happen. How would I set up the relay for the trigger? If possible, can I create and would it be cheaper to create the table setup from scratch and just buy the software to install for the system? here are the specs of my machine off of Longevity's website: Specifications: General Specifications: Genuine Infineon IGBT based electronics Operating Voltage: 220/230/240 VAC 50/60Hz Input Open Circuit Voltage: 60-80V 60% Duty Cycle @ Rated Amperages Weight: 68 lbs Thermal Overload Protection with Large Size Cooling Fan Size: 17L x 8W x 11.5H inches 20-50AMP Plasma Cutting Specifications @ 75psi: 3" Per minute @ 3/4 " Steel (Severance Cut ) 7" Per minute @ 3/4" Thick Steel 17" Per minute @ 1/2 Thick Steel Minimum requirement for air compressor: (4.0 CFM) Aluminum Cut Up to 1/2" on AC plasma cutting! 5-200AMP AC/DC TIG Features: Up Slope, Down Slop Control: 0-10 Seconds Post Flow Control: 0-25 Seconds Base Current Control: 5-250 Amps Peak Pulse Current Control: 5- 250 Amps Pulse Frequency Control: .5-25 Hz Pulse Width Control: 10%-90% AC Frequency Control: 20-100 Hz AC Balance Control: 30-70% (for Aluminum) Aluminum Weld Up to 1/2" 20-160AMP Stick Features: Arc Force Controls the amperage from 20-160AMP Pilot Arc and Contact Start: Pilot Arc plasma cutter starting technology allows you to start and maintain an ARC as long as the trigger is pressed. This ARC is a similar to the ARC you will see from an oxy fuel cutting torch. In addition, you are able to hook these torches up to CNC machines because contact with the workpiece and the tip of the torch is not required. Also because there the starting technology is not High Frequency, your plasma cutter does not interfere with CNC Computers. Pilot Arc torches also have longer consumable life because you can maintain a distance when starting an arc. Let me know if creating the table from scratch is a feasible path and the steps that I will need to take to make this happen. Thanks again.

I certainly agree with you Ken.

Here is a cut that I made with the plasma torch for a friend of mine: 1/4 square tubing. Machine was set to 25 amps.

Pictures coming soon. so far the machine is coming along just fine. The machine is made in china, but so far, the machine is shown me nothing but quality welds and cuts. It seems to be a pretty solid unit all in all. Ive made a **** load of practice welds and cuts with it so far, and it has not hesitated. Ill post some of the welds that I have completed with it so far as soon as I can fine that darn camera! Keep you guys posted. Thanks Ed

here is the correct image for this machine. posted the wrong image before.

I just made a purchase of this machine through a Longevity sales rep over the phone. I checked out Ebay and found some similar machines Like there's but none Identical to the this machine. Also, most of the ebay sellers offered only a 1 year warranty. Longevity offered me a 5 year warranty + a 30 day satisfaction guarantee on the machine. The rep over the phone was able to discount the machine for me + give me a discount on consumables and tungsten rods for the tig torch. I will try the machine through the 30 day trial and post a review.

Hi, Just hoping to hear some feedback about a welding company called Longevity. My old Lincoln TIG welder just quit on me, and I was surfing the net looking for a good buy on a new welder. I came across a company called Longevity. They seem to have pricing and warranty that is unsurpassed for there equipment, but I have never heard of them. Here is there Link: Plasma/Metal Cutters welding equipment. Here is the Link to the specific machine that Caught my eye: WeldAll 200PI Let me know what you guys think and know. Thanks.

My name is Ed Hensley, I am currently taking a black smith class at my local community college. I am here to hopefully further my eduction and knowledge with the use and help of the members of this forum. I hope that eventually, I will be able to answer some questions here myself, but for now, I will probably be just asking the questions. thanks for the future support. Ed.
