NEW MIG Machines?
This is great...
https://weldtalk.hobartwelders.com/f...125-mig-welder
BUT... Would be more interested in stepping up (from HH140), how about a machine along lines as the 210MVP but with inverter technology and infinite voltage/amperage control.....

Good stuff?..... I have used both, can not really tell much difference.........Leave a comment:

MAPP (methylacetylene (propyne) and propadiene) was discontinued in 2008 .... Was replaced with MAP-PRO, which is propylene...

Old school transformer welders with fixed step switch are fixed ratio...IF you are putting in 240 V and seeing 30 volts at tip of MIG gun transformer ratio is 8:1... Only time voltage/amperage changes (ratio) is what transformer tap you select with amperage switch...
Infinite adjust voltage/amperage...Last edited by Dale M.; 05-14-2019, 09:52 PM.Leave a comment:

Not much... Maybe a few dollars to a Craftsman Torch collector, but on open market its more of a paperweight than anything else.....

You can test motor by disconnecting it from circuit board and putting leads across 12 volt battery... If motor runs, good chance problem may be else where.... Motor is 16 volt DC so 12 volt battery will power it for testing...

Processes today have migrated to MIG welds as it introduces less heat and warping into metals.... And one does not run a bead with MIG, one does a tack weld about every 1-2 inched until butt weld is a solid joint....

First time welding and doing stairs....... Not sure if that is advisable... Don't recommend projects that could cause injury if a failure should occur as a beginners welding project....

The standard plug/receptical of welders has pretty much distilled down to the NEMA 6-50 plug/receptical across almost all manufacturers for 240V machines... Wire size and breaker capacity is pretty much dependent on load characteristics of welder, wiring and breaker does not have to be installed to...Leave a comment:

Probably will do just fine .... I weld up to 1/4 inch with my HH140 on step 4 and run C25 with .030 wire... Most high end 115V welders will do same setting for shield gas (GMAW) as flux core (FCAW)..... Door chart is a bit on conservative side (liability reasons) if you understand procedures and have...Leave a comment:

A few things...1. Keep cylinder safety caps on cylinder when not connected up to welder or torches....2. All cylinders need to be secured to wall or post or cart (chained) to prevent tipping hazard....3. Cylinders with flammable gasses (like acetylene or propane) should be stored outside so if...Leave a comment:

Plaque on welder says it draws 20 amp at 230 volts... So probably 30 amp breaker and if distance of 50 ft or less 14 gauge wire will do (absolute minimal), if you want to play it safe you can always go one size larger like 12 gauge (suggested) ....

Not sure on what helmet to buy other than it has to have some really good speeds,... One thing I have determined after suffering battery failure with sealed unit, its almost impossible to "fix" the situation, yes get helmet with replaceable batteries ( mine takes 2 AAA) .. Helmet also has...Last edited by Dale M.; 04-27-2019, 09:01 AM.Leave a comment:

Polarity is DCEN (electrode negative) for fluxcore..
DCEP (electrode positive) for solid wire & shield gas...
If you are using the demo roll of wire that came with welder its most likely fluxcore and machine was setup at factory for fluxcore (DCEN) ..

First thing I noticed it looks like you pattern or weave did not bridge both piece of metal....Also looks like you are trying to bridge to wide a gap.... You probably need to run some practice beads on some throw away stock till you beads are consistent enough to do the real work, ....

Manual for 125 (on line) looks more like 4/30 (chart on page 13) for "stainless" (bottom row on chart) ... The 4/80 is for plain (mild) steel .... Think your wire speed is to fast.... Also manual suggests 20CFH for shield gas (note 7 on page 14), but you can push it up or down a bit as...Leave a comment:

Most manuals recommend 20 CFH but you can push it up or down as long as welds produced are of good quality... What is actual CFH on left hand gauge with trigger pulled.... If substantially less than when static (trigger not pulled) probably low gas volume is part of your problem... Do you actually have...Last edited by Dale M.; 04-26-2019, 09:57 AM.Leave a comment:
