1/4" Penetration Test- HH140 vs Oxy Acetylene

admin

Here's an un-scientific test of penetration between oxy acetone and a 115v hobart handler 140 running 5v/50wire speed with .30 wire 75/25 mix @ 20cfm.Not really trying to make a point here rather just testing my new HH140 capabilities vs my old torch.It's all 1/4" hot rolled steel butt joints.From left to right:Oxy Acetylene beveled at jointHH140 non-beveled non-preheatHH140 beveled and preheatedThe 140 had trouble with the 1/4" stuff until I beveled and pre-heated the joint.Sent from my iPhone using Tapatalk

Reply:Looks like you only beveled ~25% of total steel thickness from each side on the OA test, is that correct?
