Will other consumables from other manufacturers work?The cost through Home Depot is like $89 for a set of ten. This seems just a bit expensive. I have seen other makes cost a lot less for the same cost.Note, Home Depot offers a three year warranty for $80 .Anyway this appears to bethe avenue that I am headed. Thanks, Ken 06-23-2018 \\#2 Check amazon. 40 piece consumable set for $60 CAD shipped. I’m sure even less in USD Sent from my iPhone using Tapatalk 06-24-2018 \\#3 Check Ebay 40 pcs set $26 .95 free shipping. 06-24-2018 \\#4 Stay away from the Lotos LTP5000D. Buy a Harbor Freight 62204, Northern tools Klutch 375 or 400dv, Razorcut 45, Everlast 50S, Primeweld cut 60, AHP cut 60, etc. you will be better of","cbCaiuUZ4r9JHpgH","https://ap.wps.com/l/cbCaiuUZ4r9JHpgH","pdf",91201,"English","# Troubleshooting Guide\n## Fault symptoms\n## Possible causes and solutions\n## Consumables and compatibility discussion","[{\"question\":\"What safety steps should be taken before inspecting or reconnecting the Lotos LTP5000D?\",\"answer\":\"Turn off electrical power and air supply before performing inspection and reconnection.
