4.3 installation and connection of MIG Welding
Connection and installation of the wire feeder
• Select suitable wire according to welding technology. The wire diameter must be matched with drive roll, wire guide pipe liner
and contact tip.
• Open the lid of wire reel on the wire feeder put "Wire Coil" into "Wire Reel" on the wire feeder. Attention: Wire end under the
"Wire Reel", opposite wire feeder.
• There is damping screw device in the "Wire Reel" (hex head screw will be seen when open the lid). Pull the wire reel with hand
when adjust. If resistance is over large, may adjust damping bolt: screw clockwise will enlarge the value and vice versa.
• Lead wire into "Wire Guide Pipe" of wire feeder, align wire with roll groove through "Drive Roll", re-lead "Socket Tip" and press
"Drive Roll". (If more welding wire is needed, it will be done after switching on the power).
Connection between Welder and Torch
• Insert the connector of torch into "Torch Access Hole" on the front panel of the welder and rotate the screw cap firmly.
Connection of the Connection Cable
• Connect the copper tip of the clamp which thread through the wire access hole on the panel with "-"of the "connecting tip". The
connecting cable must be reliable, or the connecting tip will burn out.
• In order to reach sound performance when welding with flux-cord wire, it's available that connect the "﹢", "-" in an opposite way,
that's the wire feed motor with "-"and the connecting cable with "﹢".
notice
Do not use steel plate or the materials alike which are ill conductor to connect between welder and work piece.
