Page 11: Installation
Installation Unpacking MMA welding Check the packaging for any signs of damage. Insert the cable plug with electrode holder into the “+” socket on the front panel of the welding machine, Carefully remove the machine and retain the packaging until and tighten it clockwise. - Page 12 Insert the multi pin plug of the interconnection cable set into the control cable socket of the welding machine and connect the other connection into the rear of the wire feed unit Ensuring that the groove size in the feeding position on the drive roll matches the contact tip size of the welding torch and the wire size being used.
- Page 13 Operation wire feeder. When pushing the torch trigger again, the Before starting any welding activity ensure that you have machine enters into crater welding, and at this time. Crate suitable eye protection and protective clothing. Also take parameters should be set by adjusting the crater/welding the necessary steps to protect any persons within the current control knob and crater voltage control knob on area.
