through the wire and tighten,press the gun switch to start.
Try to fine tuning the voltage when the current and voltage do not matched well
2.3 Flux cored wire without gas
Place the wire at the right wire groove according to wire diameter. Release the
nut on the wire pressing wheel and feed the wire to the wire groove through
wire hose. Adjust the wire pressing wheel to press the wire so it doesn't slip. D
on't over-press it. Otherwise the wire would be distorted and can't be feeded n
ormally.
Connect the wire feeder polarity plug to the negative socket;Connect the earth
clamp to the positive fast socket and tighten it clockwise.
MIG torch:Feed the wire out by wire inspection,and choose the contact tip
through the wire and tighten,press the gun switch to start.
Try to fine tuning the voltage when the current and voltage do not matched well

2.4 Lift TIG
Connect the gas pipe of TIG torch to the gas cylinder
Conenct the seperated type TIG torch to negative socket,earth clamp to
positive socket
Scratch the tungsten on the workpiece to start the arc,and then lift the tig torch
There is no control switch for gas flow and current. To avoid waste and safty
problem, please turn off the gas cylinder and keep torch away from the
workpiece.
