I,M looking to purchase this torch and get sometips for it and would like to know if they make a heating tip for it .Mostly be cutting 1/4 '' to 3/4 '' mild carbon but would also like the ability to cut 3 to 4 '' ocasionaly. The 929 needs flash back aressetors right ? I have a victor csrm360a for the acyl. and a rego 1615 for the oxy will they work with that torch?Not shure if a bigger torch needs bigger regulators.Any feed back will be appricated.
