IMP equals about .125 thousandths step. The BoreWelder current limit is not to exceed 175 amperes. 2 on the wire Speed dial is approximately 100 amps with . 3 on the Wire Speed dial is approximately 150 amps with .035 wire. Step varies directly with wire speed.
Higher amperage means higher step.
Step varies inversely with rotation speed, faster rotation speed means less step. We are looking for the wire to be pointing at the junction of the previous bead and the bae metal or slightly above. Starting voltage can be 18 volts and trimmed for best run after the welding process is stabilized. The 306-P BoreWelder is designed for safety and ease of use, but as with the operation of any machinery, safety depends on the operator. The BoreWelder requires thoughtful, careful operation to produce both optimum results and safety.
