GUIDE TO MIG/MAG WELDING
Before starng any welding acvity ensure that you have suitable eye protecon and
protecve clothing. Also take the necessary steps to protect any persons within the welding
area.
Burn back control
In the event that the welder was to stop welding and all funcons of the machine stopped simultaneously
then the consumable ller wire would in all likelihood freeze in the weld pool. In order to avoid this
happening the burn back feature is present on this machine.
This facility is an adjustable control within these Jasic compact MIG machines and it will allow the power
and gas shield to be maintained on the consumable ller wire when it has stopped feeding thereby
burning clear of the weld.
Some quick reference handy ps for the MIG/MAG welding process are:
 When welding, try to use an electrode sck out (the distance between the weld and the contact p)
of around 6-8mm.
 When welding thin materials try and use smaller MIG wire diameters and for thicker materials use
thicker wires.
 Make sure you select the correct MIG wire type for the material to be welded.
 Ensure the MIG welding gun has the correct sized contact p and type of liner.
 Always ensure you have the correct size drive rolls and torch liner for the wire size selected.
 Select the correct gas to achieve the correct weld characteriscs and nish.
 For opmum control of the weld keep the wire at the leading edge of the weld pool.
 Before commencing welding, ensure a comfortable and stable posion.
 Try to keep the welding torch as straight as possible when welding to ensure the best feed.
 Carry out daily housekeeping on the condion of the welding torch and drive rolls.
 Keep any consumables clean and dry to avoid contaminaon such as oxidaon and damp.
