Lincoln Electric 125HD WeldPak Area: Hot Metals

!!! CAUTION !!! Our welders are 20% duty cycle which means we can only be welding 2 minutes out of every 10 minutes at maximum settings or the welding unit may be ruined, if you weld for 2 minutes wait 8 minutes for the welder to cool.


Flux core or gas shielded welding of steel. Welding of aluminum with the use of the spool gun.


For use of the spool gun RTFM. aluminum requires use of argon as the shielding gas. The spool gun is in the black case on top of the grinder bench shelf (manual is inside case), it is set up to work once you RTFM.

For regular Mig welding the knurled drive roller is intended for flux core only and seems to grind some material off the wire. This will be a maintenance issue for the gun liner and I recommend we use the knurled drive only when necessary. The 125HD is configured for use with mild steel.


Additional wire drive wheels and the large spool adapter are inside the case.
